Discus fish farm - Fish body
The lateral line Running symmetrically along each side of the fish’s body, the lateral line is more or less visible, according to the species. It consists of a succession of pores that communicate with a canal situated under the skin. This important organ does not exist in any other vertebrates. While the senses of taste and smell, highly developed in fish, allow them to recognize a greater number of smells than humans, at very low concentrations, the lateral line, with its special cells, detects and analyzes the vibrations of the water and sends this information to the brain. In this way a fish can be aware of the proximity of an enemy, of a prey… or of the approach of the aquarist (see box, p. 47). The importance of the lateral line is apparent in the blind tetra (Anoptichthys jordani), which never bumps into an obstacle even though it has no eyes. INTERNAL ANATOMY The sum of the internal organs accounts for roughly 50 to 60% of the body weight in a classically shaped fish. The brain This is fairly simple in fish, when compared to other more evolved animals. The parts corresponding to sight and smell are particularly well developed, demonstrating the importance of these two senses. The skeleton Obviously, this supports the fish’s body, but it is less sturdy than that of a land animal, as a fish, partially freed from gravity, is “carried” by the water. Nevertheless, the relative fragility of the skeleton is a handicap and it is not uncommon to find fry that emerge from their egg “twisted”.
