SEMI-NATURAL REPRODUCTION Semi-natural reproduction can be carried out (Aquarium fish)

admin — Sat, 07 Jun 2008 19:37:41 +0000

SEMI-NATURAL REPRODUCTION Semi-natural reproduction can be carried out with those fish which normally live in groups and do not form stable pairs, such as the Characins. A group of ten can be inserted into a rearing tank adjusted to their requirements and left to reproduce. There are then two possible scenarios: - the adult fish are removed and the aquarist looks after the fry; - the adults and the fry are left together, so hiding places must be provided for the young - plants on the water surface, rocks, etc. The fry are not moved until they measure 5-10 mm, when they are transferred to another tank to grow into adults. The remaining adults can reproduce again as soon as the maturing phase has passed. The advantage of this method is its relative ease: one or several pairs are allowed to form and they can reproduce whenever they want. Leaving them with the eggs and fry allows a type of natural selection to come into play, whereby only the strongest and most agile will be able to escape the predatory instincts of their parents.Fish with adhesive eggs Fish such as the Characins that do not look after their offspring lay them on fine-leaved plants (like Myriophyllum and Cabomba), which you should make available in the aquarium. Alternatively, it is possible to use a web made of Perlon wool, which is commercially available for use in filters. This provides a very good artificial support. The parents must be removed after the eggs are laid. Some species not only look after their eggs, but also sometimes their fry. Some, such as the scalares, lay their eggs on a plant with hard leaves, while others, such as certain American Cichlids, do so on a vertical or horizontal rock face. An artificial laying support can also be provided, by using a PVC tube or plate, for example. Other Cichlids - Africans from Lake Tanganyika or Americans, such as species of the Apistogramma genus - lay their eggs in a cavity or small cave, sometimes even on the ceiling, if this is the only suitable place. In all cases where the eggs are laid on a rigid support, this is generally cleaned by one of the parents before the female deposits the eggs that the male will go on to fertilize. The male will then defend the site against any possible enemies, while the female ventilates the eggs with her fins. There are some occasions when the parents swap roles, and others when one of the two even separates out dead eggs, distinguishable by their opaque white color. The fry are then supervised by their parents until they are independent.

CARING FOR THE PARENTS (Aquarium fish) Successful reproduction depends on

admin — Wed, 04 Jun 2008 01:31:18 +0000

CARING FOR THE PARENTS Successful reproduction depends on the good health of the reproducing fish, and to achieve this they have to remain undisturbed, and therefore isolated, in a rearing tank. Their feeding is especially important, as the quality of the eggs, and above all that of the vitellin, depends on it. Fresh food, particularly live prey, must be provided, with an emphasis on variety. Although artificial food can be used as a substitute, it must never constitute the basic diet.EGG-LAYING One encouragement for egg-laying is light, whether it is the morning sun or the aquarium’s artificial lighting. Also, if you think that your fish are taking a long time to lay, you can change around 10% of the water volume, and this may provide them with the stimulus they need. Fish with free or non-adherent eggs When the eggs fall to the bed, they must be protected from the voracity of other fish - and this can be done in a normal aquarium. There are a couple of ruses that are useful in this situation: - divide the aquarium into two horizontal sections by means of a grille which only lets through the eggs; - cover the bed of the aquarium with glass marbles - the eggs will slide between them and can easily be recovered by siphoning them off. Most fish that produce free eggs do not take care of them, and the parent fish must therefore be removed from the tank to ensure that they do not devour them. There are some species within the Cyprinodontid family whose eggs can survive outside water, provided they are kept within a moist environment.

Aquarium Fish - The Rearing Tank

admin — Sat, 31 May 2008 09:19:12 +0000

This is normally modest in size, as it is used to isolate a pair of reproducing fish and their future offspring. There is no need for a bed, except for some species (the Cichlasomas, for example). A rearing tank must be heated but only moderately filtered. Avoid any systems which may “swallow” the eggs and the fry. Aeration is not obligatory. Fill the tank with water taken from the parents’ aquarium, which can then be gradually modified to obtain the precise characteristics required by the reproducing fish (pH and hardness). A support should be provided for the egg-laying, and this can be either natural (plants, rocks) or artificial (PVC). More detailed information on this subject, family by family, can be found below. REPRODUCTION STRATEGIES Reproduction ensures the survival of a species, and nature has planned several strategies for it. In the case of small eggs produced in large quantities, these are often transparent, in an attempt to hide them from their predators. As for large eggs, if there are only a few their parents protect them most of the time. In both cases, the aim is to reduce the number of losses as far as possible. In an aquarium, the intervention of the fishkeeper considerably increases the chances of success, and the survival and proliferation of a species is normally guaranteed. Reproduction techniques for aquariums These vary according to the different families of fishes, and they will be discussed in greater detail in the “Catalogs of Fishes” (pages 75 and 126). However, it is possible to advance some general precepts on the subject here. Choosing the reproduction site Reproduction can occur spontaneously in a mixed tank, or in a specialized or “regional” aquarium. This often happens with novice aquarists, unaccustomed to spotting the approach of egg-laying in a female. In such cases the future of the fryis a matter of chance. Some of them will serve as prey for the other inhabitants of the tank, and the survivors are sure to have problems in getting enough to eat. since they have to compete with adults. This is why it is advisable to use a tank specially intended for reproduction. Choosing the reproducing fish Although it is sometimes difficult, at the best of times, to distinguish between males and females, it is easy enough to spot a female’s swollen stomach and the attentions bestowed on her by one or several males - signs of the approach of the mating season. It is therefore time to transfer the fish in question into the rearing tank prepared for this purpose.

Fish Classification - General Principles

admin — Wed, 28 May 2008 07:27:23 +0000

Most fish kept by aquarists are oviparous (egg-layers), but there are some exceptions - viviparous fish (or livebearers). A varied and rich diet enables fish to accumulate reserves of proteins and lipids, which help them form eggs and spermatozoa. This is the maturing phase. When the female’s ovary swells, she is ready to lay eggs. This only needs a stimulus to trigger it off, such as, in the natural setting, rain, sunlight, or moonlight (research is presently in progress on the influence of the moon on reproduction). In an aquarium, egg-laying is sometimes sparked off by the early morning sunlight, which beats down on the tank with varying degrees of intensity, or by a partial change of water. The laying of eggs can be preceded by a courting ritual, during which the male seduces the female or, in rare cases, bullies her and violently sees off any rivals. The female then expels her eggs into the water, and these are immediately fertilized by the male. This is obviously only a general description that leaves room for the huge diversity found in aquarium fish, particularly as regards the future fate of the eggs: they can be abandoned, or even sometimes eaten, by their parents, or they can be guarded and defended in the first days of their life, and a similar variety of parental behavior is found in the treatment of the developing fry. The incubation of the eggs, which lasts several days, sees the development of the embryo. When this is completely formed, it moves about until it breaks the egg’s membrane: this is the hatching. A larva emerges, differing from an adult in its form, size, and the proportion of certain organs. The larva has highly developed eyes, for instance, allowing it to spot its prey. It also has a vitellin vesicle, which provides it with food reserves during the first days following its emergence from the egg (except in livebearers of the Poeciliid family). The larva gradually evolves, over the course of a few days or weeks, depending on the species, and modifies its behavior to become more and more like an adult. It turns into fry. 4 -juvenile THE VITELLIN SACK The vitellin sac, or vitellin vesicle, constitutes the fish larva’s food reserves in the first days of its life. It derives from the vitellin of the egg - the equivalent of the yolk in poultry - accumulated by the female over the course of the maturing process. It is sent along the blood vessels, which distribute these reserves around the body of the larva. This allows it to survive until it is able to catch prey itself, i.e. a few days after emerging from the egg.

A hard-boiled egg yolk is added to water in a glass. This forms microparticles which are then sieved. This nutritious liquid is then given to the fry, taking care not to put too much into the tank, as it is always important to minimize pollution. Egg yolk, rich in proteins and lipids, can be used as a complement or as a replacement for other food. REPRODUCTION In the world’s temperate regions, the reproduction of fish generally depends on the season: in other words, it is determined by the temperature. There is only one high season, during which a species usually reproduces only once. In a tropical setting, where variations in temperature are less important, other factors influence on reproduction, especially rain. Fish can lay eggs several times a year, at intervals of sometimes less than a month. THE KEYS TO SUCCESSFUL REPRODUCTION - Have well-fed and healthy parents. - Provide them with the best possible environment: a rearing tank; high-quality water, with characteristics as close as possible to their native setting. - Anticipate how you are going to feed the fry.

Freshwater Fish For Sale - Infusorians

admin — Wed, 21 May 2008 20:01:24 +0000

Infusorians These are microscopic, unicellular animals, easy to produce in fresh water. They are usually present in small numbers in an aquarium. Riccia, a surface plant, gives them a chance to grow, as they find food (organicmatter) on its leaves. They can also be produced by leaving a piece of potato, a lettuce leaf, or some paddy rice (unhusked rice, available in grain stores) to soak in a receptacle containing aquarium water. What if a fish does not eat? Sometimes a fish refuses to eat, or appears to be incapable of doing so. It is therefore a question of finding the cause and eliminating it. A newcomer to a tank rarely eats on the first day. This is normal, as it feels GOLDEN RULES FOR FEEDING - Give fish a varied diet; - give them a little, but often. Two portions a day is ideal. For fry, the feeding can be more frequent. - do not wait until the fish are sated and stop eating. Stop feeding once the ration is complete; - siphon off any food surplus as quickly as possible, as the leftovers are pollutants. In captivity, the fry can be fed with brine shrimp nauplii and then with fine commercial powders. lost in its new environment. Small species and more lethargic fish are often dominated by their bigger and faster cohabitants at feeding time. They must therefore always be fed separately, preferably with mobile, live prey, once the other fish have been distracted by other food. A fish can also refuse to eat if it is sick, and this will be reflected in its behavior, color, and other symptoms which may eventually be seen on its body. In this situation it must be isolated in another aquarium, treated, and given rich food. comprised of live prey or fresh produce. Sometimes fish can systematically refuse to eat artificial food, although this is rare in fresh water, but less so in marine aquariums. There is no point in being stubborn: change to a varied diet based on live prey and homemade fare.

Buy Fish Online - Breeding

admin — Wed, 07 May 2008 23:40:11 +0000

BREEDING BRINE SHRIMPS The dry eggs (known as cysts) are available in aquarium supply stores. They must be kept away from light and moisture. In order to make them hatch, salt water must be prepared with the following characteristics: temperature 25 C, salinity 35%, i.e. a specific gravity of 1.023. The salt water can be natural or reconstituted with special aquarium salts, or even with rough kitchen salt (easier for aquarists who do not keep marine fish). The water can be colder and less salty (up to 20 C and 20%, i.e. a specific gravity of 1.014), but the hatching rate will be lower (50-60% against 80-90%). Any small glass or PVC container can be used - bottles, for example - although specialist equipment is available. The eggs are placed in the still water for a quarter of an hour, the time required for their rehydration. If we estimate that 250,000 eggs weigh around 1 g, a tiny amount (the tip of a knife, for example) will produce sufficient brine shrimps. Aerate the water slightly to produce small bubbles, which will disperse the eggs, but be careful not to stir the water too vigorously, otherwise some of the eggs will crash against the sides of the container and will not hatch. The hatching occurs after 24-36 hours at 25 C, or after up to 48 hours at 20 C. Finally, switch off the aeration: the empty shells will float to the surface, the unhatched eggs will fall to the bottom, and the brine shrimp nauplii will be swimming just under the surface. It is then easy to siphon them off (with an aeration pipe, for example) and strain them through a small filter (available commercially), or, alternatively, through the thin mesh of a piece of old curtain, or even a very fine pantyhose. To make this operation easier, you can group the nauplii together using a flashlight, as they are attracted by light. You can then go on to feed them to the fry. They will only survive for a few minutes outside salted water, and they will not eat on the first day after hatching. If you want to keep them for several days to obtain larger or more mature larvae, special food is commercially available. This makes it possible to keep brine shrimps until they are adults. ADULT BRINE SHRIMPS Adult brine shrimps are sold live in small sealed sachets containing salt water and air. They are passed through a sieve before being given to the fish, which enjoy hunting them down. They survive for a few minutes in unsalted water. Brine shrimps can also be bought frozen.

Tropical fish - Food Distribution

admin — Sun, 04 May 2008 18:05:51 +0000

When they are healthy and well adjusted to captivity, fish eat at a regular time and become accustomed to the spot where the food is given out. It is advisable to divide the daily ration into two parts - one in the morning and one in the evening, for example. The end of the day - 1 or 2 hours before turning the aquarium lighting off - is usually the most practical for the aquarist. In any event, food distribution offers a special opportunity to observe the behavior of your residents and check their state of health. Allowing the fish to come and feed out of your hand is particularly enjoyable, but take care, because some large specimens have impressive teeth! If the water is too agitated, artificial or natural food may be dispersed too quickly and washed to a corner of the aquarium where the fish will not be able to recover it. thereby creating a potential for pollution. The stirring of the water must therefore cease when food is being distributed and eaten. Feeding the fry When they are born, the fry of egg-laying fish feed on the reserves in their vitellin vesicle, as their mouth does not open until a few days later. They will then often accept the fine powders which are available commercially. If this is not the case. give them brine shrimp nauplii for a few days - newly hatched nauplii are most suitable for the first two days. After that, they can be offered nauplii that are 48 hours old. Daily production over a period of several days must therefore be planned for. If brine shrimps are unavailable, another option is the production of infusorians. Live-bearing fish (the Poeciliid family) accept artificial food from birth, and they also thrive on brine shrimp nauplii. As for marine fish, rotifers, discussed above, should be Automatic food distributor for artificial food. Each section corresponds to a daily dose.used, as they easily fit into the small mouths of the fry.

Aquarium Fish - Small Fish

admin — Thu, 01 May 2008 05:28:45 +0000

Either fry or small fish can be used to feed marine fish doubtful about artificial food, or large freshwater fish. With this in mind, some aquarists breed prolific species that reproduce easily (Poeciliids, for example). Other live prey (larger than 1 cm) Keeping and breeding worms or insect larvae is also possible, though it sometimes proves time-consuming. The range of live prey listed above is adequate for the needs of your fish. Planktonic food Freshwater or marine plankton contain a host of organisms barely visible to the naked eye (0.1-1 cm) but valuable for feeding fish, especially the fry. Collecting them in a natural setting is tiresome, and involves a risk of introducing potential microscopic hosts into the aquarium and spreading disease. Some planktonic food is available on the market in frozen form. Brine shrimps This is the “magic” food that every aquarist should breed. This primitive crustacean grows to 1 cm when adult and is called Artemia salina. They live in the heavily saline waters of salt marshes, feeding on the micro-algae that they gather with their filtering legs. Their characteristic most relevant to the aquarist is that their eggs can be stored dry, with their development interrupted, for use later on. Once the eggs are returned to salty water, they hatch rapidly and produce a larva called a nauplius, which measures only 0.3 mm and is particularly suitable for feeding to fry. Feeding brine shrimps to fish is easy, even for an amateur (see box). They are still too big for the fry of some fish, however, especially marine species. In such cases, it is possible to use rotifers, animals halfway between worms and crustaceans, which have a crustacean-like shell and never grow to more than 0.2 mm. Rotifers These are more complicated to breed than brine shrimps, as they must be fed planktonic micro-algae which also need to be cultivated. It is therefore best to obtain them from a laboratory specializing in oceanography or marine biology, and to get advice on the essential steps required to look after them for a few days - the time within which the fry for which they are intended will be big enough and sufficiently developed to move on to a diet of brine shrimp nauplii.

Aquarium Plants For Sale - Bloodworms

admin — Sun, 27 Apr 2008 21:04:33 +0000

In fact, these are not worms but the aquatic larvae of various species of nonbiting mosquitoes. They are also commonly used as bait in fishing. Although it is sometimes thought that they live in mud, they are actually found in the water of areas that are well endowed with organic matter. It is useless trying to collect them yourself, but they are sold in the aquarium trade. They keep for a few days in the refrigerator, wrapped in moist newspaper. They are a good source of nutrition, as they are rich in protein. Tubifex worms These are worms that are gathered from the mud in environments rich in organic matter. Some people think that they represent a risk when they are introduced into an aquarium, as they may carry undesirable bacteria. This risk is very slight, however, and there have been no reports of any serious incidents. The specimens which are commercially available can be kept for a few days in the refrigerator, in domestic water, but it is Rich in proteins, bloodworms are a prey much appreciated by carnivorous fish. essential that this water is changed every day. Shrimps Flowing and welloxygenated fresh water are home to small river shrimps of up 2 cm that swim along the banks. These are rarely sold live, but they can be found in a freeze-dried form. You will find that your fish will definitely enjoy them. The small marine shrimps found on some coasts are also highly prized, especially by marine fish. These are often sold in fishing stores along the coast. If you are lucky enough to live in such an area, you can also collect them yourself and keep them in an well oxygenated seawater aquarium. Both types of shrimps can be frozen after being cooked and rinsed under the faucet, or they can also be ground and turned into a homemade dish.
