Pages 2 (502 words)
The research of R. C. Vrijenhoek entitled Conservation Genetics of Freshwater Fish focus on the utilization of putatively neutral molecular markers in the study of conservation genetics. Admitting that the use of this particular method is still highly debated among scientists, he stresses its indispensability and efficiency: "Molecular markers have proven their usefulness in solving many difficult taxonomic problems with endangered species, in designing and monitoring captive breeding programmes and understanding breeding systems, in detecting geographical structure of genetic diversity, in managing gene flow, and in understanding factors which contributed to fitness" (15).

Extract of sample

Thus, the conservation genetics of freshwater fish becomes important as it allows the resolution of problems among taxonomically difficult groups, design of captive breeding programs, detection of diversity within and among geographical population, management of gene flow, and understanding factors which are essential in the maintenance of the species' fitness (2).
The research also expounded on the importance of captive breeding for: "conservation and rescue; stocking and supplementation of sport and commercial fishing; domestication and selective breeding of food and ornamental varieties; experimental research organisms; and exhibition and education" (3). ...

An environment is made up of resources. Resources refer to existing means of supplying what is needed or a stock that can be drawn on. Renewable resources are those that can be regenerated at a constant level. This is because they recycle rapidly, is alive or has the capacity to reproduce and grow. Examples are water which can be recycled, organisms because they can reproduce and many others.…

Freshwater fishing is more difficult than saltwater fishing.
This body constitutes just three percent of the earth's water while the rest ninety seven percent constitutes saltwater and includes water in the oceans. Only about one-fifth of the world's total fish catch comes from fresh-water fisheries, while the rest comes from saltwater. Going by simple arithmetic, freshwater fishing has a lower input to the fishing industry than saltwater fishing.…

The essay provides us with an honest…
