Fishery can mean either the enterprise of raising or harvesting fish and other aquatic life [1] or, more commonly, the site where such enterprise takes place ( a.k.a., fishing grounds ). [2] Commercial fisheries include wild fisheries and fish farms, both in freshwater waterbodies (about 10% of all catch) and the oceans (about 90%).The popularity of shellfish has been increasing worldwide, with a consequent increase in adverse reactions that can be allergic or toxic. The approximate prevalence of shellfish allergy is estimated at 0.5-2.5% of the general population, depending on degree of consumption by age and geographic regions. The manifestations of shellfish allergy vary widely, but it tends to be more severe than ...Shrimp are America's most valuable and most popular seafood.

the resource is the common goal of all shellfish management programs. Genetic factors affect this goal because shellfish are the products of their genes, the environment and interactions between the two. The genetics of shellfish, in connection with the environment, determine the quality and persistence of a shellfish resource (Gaffney, 2006).Density (range, 100-3,500 clams/m 2) and mean clam length (range, 17.4-31.6 mm) did not correlate with salinity, sediment trace metal concentration, silt content, nutrient concentration, or anthropogenic land use.
