FISH TIDBITS 
Largest collection of Fish
The largest collection of fish in the world is in the National Museum of Natural History located in the National Mall, Washington DC, USA. The Museum has 540,000 lots of fish (a lot is described as a set of similar specimens collected at one time and at one place). These fish include about 4 million species. The first fish to enter the catalog ledger of the Museum was a Suckerfish, Catastomus hudsonius on the 15th of December 1856 collected by S.F.Baird at Lake George, New York in 1850.
An important Sport Fish
White Bass (Morone chrysops) is a silvery grey fish that grows to a total length of 18 inches. It is found in large streams, lakes, and reservoirs from across Winnipeg, Mississippi river systems up to New Mexico. The fish swims in schools in open waters feeding on aquatic invertebrates and small fishes. Minnows are used as excellent baits to catch this Sport Fish.
Reef fishes
Coral reefs are massive structures of limestone formed from millions of tiny colonies of animal polyps (Coelenterates). When the polyps die, they leave behind hard stony branching structures. Coral reefs are excellent habitats in warm clear oceans, teeming with life. Fishes that live in the corals are called reef fishes. They have two stages in their life history, the pelagic (open sea) and the benthic (bottom). The pelagic larval stage swims freely and settles at a new place in the coral reef. The stage is important for dispersal of reef fishes.
Lateral Line Sense Organs
Many fishes have receptors that are sense organs of taste and smell. Their sense of hearing is feeble. But fish can detect vibrations and movements of other aquatic organisms by a special system of cells and nerves located beneath the skin on either side of their body called the lateral line sense organs. Fishes detect their prey and predators by this sensory system apart from using their vision and smell.
Viviparous fishes
About 3 percent of fishes are viviparous. The mother fish retains the eggs and the developing embryos derive nutrition from the mother until they are delivered free.
Surfperches, Split fins and Lemmon sharks have a structure that connects the mother’s blood supply to the embryo similar to placenta in mammals.
