Abstract Lakes, rivers and oceans provide unique resources support fisheries aquaculture worldwide. The sector of Kenya contributes approximately 0.8% to the country’s GDP. Marine production is about 9 000 tonnes per year. finfish form bulk marine production, while shellfish (e.g. prawns, lobsters crabs), molluscs octopi squids) are underexploited. Fishery has potential USD 5 billion for Blue E...

Title of Document: THE EFFECTS OF WATER QUALITY IMPROVEMENTS ON A COMMERCIAL FISHERY: EVIDENCE FROMTHEMARYLAND BLUE CRAB FISHERY Sarah Ball, Ph.D., 2014 Directed By: Associate Professor Doug Lipton, Department of Agricultural and Resource Economics Developing and implementing total maximum daily loads (TMDLs) is a costly and controversial process. However, there are many potential benefits, suc...

A coastwide bloom of the toxigenic diatom Pseudo-nitzschia in spring 2015 resulted in the largest recorded outbreak of the neurotoxin, domoic acid, along the North American west coast. Elevated toxins were measured in numerous stranded marine mammals and resulted in geographically extensive and prolonged closures of razor clam, rock crab, and Dungeness crab fisheries. We demonstrate that this o...

Sperm depletion in males can occur when polygynous species are intensively exploited under a male-biased management strategy. In fisheries involving crabs species, the effects of this type of management on the reproductive potential is far from being understood. This study tests whether male-biased management of the principal Chilean crab fishery is able to affect the potential capacity of Meta...

As recreational fishers act relatively autonomously, management relies heavily on voluntary compliance. Therefore, understanding fishers’ views options can be beneficial. This study used a two-phase approach of face-to-face interviews and subsequent online questionnaires to evaluate salient issues affecting the Blue Swimmer Crab (Portunus armatus) Black Bream (Acanthopagrus butcheri) fisheries ...

During the past 12 years fishery managers responsible for federal fisheries off Alaska have developed and implemented three new fishery management limited access/quota share programs in place of traditional open access management. The three limited access programs are unique but each provides for the allocation of quota shares to individual participants in the halibut and sablefish longline fis...

Given the economic and social importance of fisheries in the Gulf of Mexico large marine ecosystem (LME), it is imperative to quantify the potential impacts of the Deepwater Horizon oil spill. To provide a preliminary perspective of the consequences of this disaster, spatial databases of annual reported commercial catch and landed value prior to the spill were investigated relative to the locat...

Mangroves are disappearing rapidly worldwide despite their well documented biodiversity and the ecosystem services they provide. Failure to link ecological processes and their societal benefits has favored highly destructive aquaculture and tourism developments that threaten mangroves and result in costly "externalities." Specifically, the potentially irreparable damage to fisheries because of ...

Small-scale fisheries along the Swedish west coast are often operated by using small vessels, targeting multiple species means of pots and gillnets. Fisheries shellfish such as European lobster ( Homarus gammarus) , edible crab Cancer pagurus ) have a relatively high economic value. However, gillnet demersal fish currently diminishing primarily due to depleted stocks increased seal depredation....
