He is constantly moving, but the largest concentration of this fish still falls on the coastal areas and surrounding Islands. Apparently, this is due to forage base Marlin.
Marlene is a thermophilic fish and to meet him outside of tropical latitudes is almost impossible. Although scientists observing the migration of Marlin, revealed an interesting fact: a few fish had rounded the Cape of Good Hope and were thus in the Atlantic ocean. And some instances during migrations cover great distances, from Brazil to the lesser Antilles. However, scientists are inclined to believe that this is the exception rather than the rule and usually Black Marlin does not make such long distance travel. Continue reading

The species of fish.

Since the fish bred in aquariums generations, there was a clear tendency to choose the most colorful animals for breeding. So many of the most popular tropical aquarium fish kept today, have more vivid coloration than their wild forms. Modern methods helped to selekcioniruut varieties from original wild forms taken from natural habitat, to new forms, genetically-modified breed, and available for every aquarist.

The science of genetics, explores the possibility that species characteristics pass from one generation to the next. The characteristics of all living organisms, including fish, are contained in genes, which are rod-shaped structures called chromosomes, present in the nucleus of every living cell in the body. Mutations, or sudden changes in genetic structure can occur, and sometimes result in a change in the appearance of fish, such as coloration, body shape and fins. When there is a mutation in certain cells eggs or milk, the change is transmitted to the next generation. Most mutations are only carried out minor changes that can be improved by selective breeding over many generations. Continue reading
