The article dwells on conservation-based management of aquatic species. In particular, exploited fish types in various ocean waters have been highlighted in the article. There are a number of unprecedented requirements that have been imposed by the various fish species especially when it comes to the need undertake real-time management of assorted fisheries. For instance, the Pacific salmon is known for its complex adaptive nature.

The management process entails several steps one of which is identification of different fish species found in both fishers and sea waters. In order to make informed management decisions, incorporating abundant information is vital. In addition, population-specific timing of the available fish species comes in handy in conservation-based management.

The researchers achieved an extremely accurate approximation of stock make-up for salmons that reside in River sockeye. Attaining such a high degree of accuracy would not have been possible without utilizing qualitative methods such as complex genetic variation which is also a major histocompatibility complex.

The researchers in the article carried out an analysis entailing a total sum of 9300 salmon fish species. The survey was undertaken in Fraser River sockeye within a period of 2 months. In order to obtain an unbiased sample, salmon fish were extracted from mixed stock fisheries. The experiment was instrumental in finding out stock-specific exploitation objectives controlled by conservation needs.

The Fraiser River drainage was the most important sample ground for the salmon fish. Data on geographical locations and key tributaries of the river were used by the researching team. This meant that gathering known samples was a crucial and initial procedure. From the article, 140 operculum punches were obtained in 1999. The latter was followed by mixed stock samples in the lower region of Fraser River and test fisheries. Either fin clips or operculum punches were used to extract DNA samples. After DNA samples had been collected, the process of laboratory analysis followed. It was necessary to analyze the different samples so as to come up with the right evaluation.

The results indicated that timely and accurate information is fundamental in effective fishery management. From the analysis, accurate results were obtained from GSI data.
