List of Fish Species -- Fish Photos - Phillip Colla

To avoid the possible harmful effects that introduced fish species can cause, there are a few simple rules you can follow: don't stock waters with live fish unless you have a permit by DEC; don't release baitfish into a water body at the end of a day's fishing even if you doubt they will survive; and don't use live baitfish in waters expressly forbidding this.

Those most in jeopardy were the smaller fishes with specialised eating and sheltering habits. []

Parrotfish are a fairly large family of at least 10 genera, found in reef environments in the Indo-Pacific region and also the Caribbean region. They are of critical importance to the reef environment, because they clean the coral of algae and sponges on both the sea side and the land side. Only a few species are fished commercially.

Scientists believe that there are more than 24,000 different species of fish in the world. Leather fish has elongated body, plump and large, flat head. The color is dark gray on the back, clearing towards the belly, and whitish below lateral line. Large species, reaching over 1.30 meters in total length and just over 20 kg of weight.

Spawning:
As with most ancestral species, alligator gars are long living, and sexually late maturing. Most females do not reach sexual maturity until after their first decade of life while males reach sexual maturity in half that time. The conditions must be precise for a successful spawning to occur. Preparation for spawning begins in the spring with the extended photoperiod and rising water temperatures, but flooding is also necessary to trigger the event. When rivers rise and spread over the floodplain, they create oxbow lakes and sloughs, and inundate terrestrial vegetation which in turn provides protection and a nutrient rich habitat for larval fishes, and fry.

Apart from these similarities, however, many of the species in this group differ markedly from one another. Fin fish like salmon have gills, are covered in scales, and reproduce by laying eggs. Eels, by contrast, have worm-like bodies and exceedingly slimy skin. Lungfish gulp air. Whale sharks, the largest fish, give birth to live young and eat only tiny fish, squid, and plankton. Some species, such as the weedy sea dragon, are so bizarre they seem almost unreal.One reason fish are so diverse is that 70 percent of the planet is covered in water. The animals in this group live in a variety of habitats ranging from coral reefs and kelp forests to rivers, streams, and the open ocean. Another is that fish are very old on the evolutionary scale. According to fossil records, they have been on Earth for more than 500 million years! The total number of living fish species—about 32,000— is greater than the total of all other vertebrate species (amphibians, reptiles, birds, and mammals) combined.Fish have developed special senses, too. Because water transmits sounds, disperses chemicals, and conducts electricity better than air, fish rely less on their vision and more on their hearing, taste, and smell. Many can detect motion in the water using a special row of scales with sensors known as the lateral line. Others can find their prey and even navigate by detecting electrical charges.There are more than 120 species of pufferfish worldwide. Most are found in tropical and subtropical ocean waters, but some species live in brackish and even fresh water. They have long, tapered bodies with bulbous heads. Some wear wild markings and colors to advertise their toxicity, while others have more muted or cryptic coloring to blend in with their environment.
