Stomach content analysis provides important insight into fish feeding patterns. Feeding of fish represents an integration of many important ecological components that included behaviour, condition, habitat use, energy intake and inter/intra specific interactions, etc. Accurate description of fish diets and feeding habits also provides the basis for understanding trophic interactions in aquatic food webs. Conceptually, trophic relations of fishes begin with foods and feeding behaviour of…

In this case study, scientists researched Lepomis microlophus (redear sunfish), Lepomis macrochirus (bluegill sunfish), and Microterpus salmoides (largemouth bass) that were collected from control ponds, natural lakes, and stormwater ponds in Orlando Florida. The fish were analyzed heavy metals such as zinc, lead, copper, cadmium, and nickel. The purpose of the study was to determine if the fish from the stormwater ponds had higher concentrations of these metals, and if there was a difference…

This week the central theme of the text is to follow the shifts in the main food source and the dependence on tools, weapons and etc. For example, The Lummi were dependent on salmon for thousand of years for an important resource the Lummi built logjams in salmon breeding areas due to eroded lands to keep their main resource. With the Northwestern Indians strong cultural, economic and political ties to salmon reaching beyond the borders decreasing challenges to their main food supply was…

Have you seen parasites in the mouths of striped bass you have caught on Lake Lanier? What you are seeing is most likely a parasitic copepod of the genus Achtheres. Achtheres is a parasitic copepod that infects the gills of freshwater fish and is most easily visible once they mature and move into the fish’s mouth. For those that haven’t seen them, mature adults resemble a small white dot (less than 1/8”) with what look like legs. Those ‘legs’ are actually the egg sacs of the female parasite…

Aquaponics in America could feed the world. The reason I'm researching aquaponics is that I am interested in providing food to the world. I don't believe anyone should go to bed hungry especially children. With the poor diet of today's culture, many adults and children are suffering from metabolic syndrome or prediabetes. This is the first time in recorded history that a population is dying from over eating. The environmental factors of our industrial culture, our traditional agriculture…

AquaBounty are greatly advantaged for its cheap production cost of GMO salmon. Its position in the first quadrant stipulates that the cost-effectiveness is an added value to the technology and the fish industry. This will be an important success factor for AquAdvantage Salmon to emerge in the market with a strong selling point. Cost has a high importance input, as seen in Figure 1, as AquaBounty performs best in this area in comparison to its competitors. AquaBounty are able to lower their…

On a global scale, fish has increasingly become an important food source. Today, our demands far exceed the sustainable yield of fish in our oceans. Our responses towards this issue have included the industrialization of fishing and fish farming. But fish, one of our most important sources of high-quality protein, provides some 16% of the animal protein consumed by the world’s population, (Food & Agriculture Organization, FAO, of the United Nations, 1997). For this reason, fish stocks are being…

mainly fish. A fishery can refer to the fishing vessel, equipment and crew involved in the harvesting; the area that the fishing activity occurs in; and/or the species of interest. These can be wild captured seafood or seafood harvested through aquaculture. Commercial fisheries can also refer to the whole process of catching, processing and marketing the seafood for sale and involves the entire business of harvesting seafood. (Blackhart, Stanton & Shimada, 2006). It applies to both recreational,…

With this into account, it is not a understatement to proclaim that the aquaculture industry is essential for the security and growth of Canada, Mexico, and the United States economies. The ocean and fishing industry are major contributors in the promotion of local commercial cultivation and food supply. With growth on a local level for aquaculture, the ripple of economic prosperity is felt across the continent. Unfortunately, there has been a gradual decline…
