The role of brackishwater shrimp aquaculture as an export industry has risen rapidly in the last ten years as the Government of Indonesia (GOI) has become concerned about increasing export earnings from non-oil exports. Limited GOI investment funds, because of drastic reduction …

The feeding of plant proteins to fish results in generation of a high amount of phytate because fish cannot effectively digest it. The hydrolysis of phytate by microbes in the environment release P which can stimulate eutrophication. This study was conducted to express phytase g…
This dissertation investigates the tradeoffs between floodplain agriculture and fisheries production in the Brahmaputra river basin of Bangladesh, where both sectors are simultaneously affected by floodplain development policies. Our goal is to study the impact of development po…
This study developed a robust technique for the assessment of morphometric differences among overwintering northern fish populations. Arctic charr were sampled soon before the freeze-up and just after ice break-up at two subarctic Quebec lakes. A homogenous sample of 397 fish wa…
One of the major limitations of aquaculture has been the inefficient digestion of phytate-bound phosphorus in plant-based diets. The enzyme phytase has been found to degrade phytate into a form that can be utilized by non-ruminant animals. The goal of this research was to produc…
Channel catfish (CCF), Ictalurus punctatus, gut cells associated with innate or acquired immunity were characterized based on their reaction to monoclonal antibodies (mAb) using flow cytometry, histochemistry, immunohistochemistry, and enzyme staining techniques. Isolation of gu…
Photobacterium damsela subsp. piscicida, formerly Pasteurella piscicida, is an important new pathogen of hybrid striped bass cultured in brackish water on Louisiana mariculture farms. Louisiana isolates compared with strains of P. damsela subsp. piscicida from Greece, Japan, Isr…
Performance by stocked brook trout (Salvelinus fontinalis) differs with respect to the native species present in the community into which the trout are placed. Understanding the dietary and habitat requirements of the native species, and how the brook trout alter the ecosystem, …
This study analyzed the productivity, production technology, and technical efficiency of cultured shrimp production in Asia using data from Network of Aquaculture Centres in Asia-Pacific. Based on the farm-level information, partial productivity ratios and dual cost total factor…
Worldwide declines in fish stocks in the twentieth century have led some governments and international conservation organizations to embrace local marine resource management systems which are often based on environmentally-friendly fishing techniques, sacred sites, and local eld…
Since 1998, episodes of mass mortality have occurred in populations of common carp Cyprinus carpio carpio and koi Cyprinus carpio koi. A herpesvirus, termed koi herpesvirus (KHV) isolated from infected fish has been shown to be the cause of the disease which has now been detecte…
The major aims of this study are to: (1) Assess the relative degree of heavy metal and chlorinated hydrocarbons contamination of fish products collected from several different locations and times from the Mediterranean Sea and Atlantic Ocean; (2) Conduct health risk analysis of …
Condition indices are widely used to generate biological insight. However, purported relationships to indices are imprecise or inconsistent in the wild. I investigated factors influencing relative weight (Wr), a condition index commonly applied to fish. I first examined the rela…
This thesis studies the optimal management of the Indonesian Wild Shrimp fisheries in conjunction with shrimp farm production. Recruitment of mature wild shrimp is related to the size and fecundity of the spawning population, and the environmental carrying capacity. Captured wil…
The research problem of the study was to determine if two low-cost “home-mix” duck feeds developed by the Development Service Center could produce equivalent egg production in Khaki Campbell ducks compared to a high-cost “commercial” duck feed. Results from this study could be u…
At least ten fish stocks migrate in the Gulf of Thailand and are shared by Cambodia, Malaysia, Thailand, and Vietnam. This biological phenomenon became important in fishery management after these four littoral states extended their national jurisdiction and claimed the 200-mile …
Channel catfish leukocytes demonstrated cytoplasmic staining patterns very similar to mammalian leukocytes when stained for acid phosphatase, a-napthyl butyrate esterase, b-glucuronidase and Sudan Black B. Monocytes, macrophages, neutrophils and possibly immature lymphocytes wer…
This is the first characterization of paddlefish (Polyodon spathula ) leukocytes and lymphoid tissues by enzyme cytochemistry, and the first study of lymphoid tissue ontogeny. Paddlefish monocytes/macrophages, T and B lymphocytes and granulocytes were positive for acid phosphata…
The discharge of untreated domestic wastewater results in well-documented environmental health hazards. In many poor areas of the world the costs of constructing, operating, and maintaining mechanized wastewater treatment facilities is prohibitive. Given limited resources and co…
