A Study on the Management Strategies for Biotech Pets: Taking the Glowing Ornamental Fish Marketed by Company A as an Example

LIN, YU-HO 15 July 2008 (has links)
Abstract The genetic engineering industry for ornamental fish refers to the industry that applies biotechnology to ornamental fish to develop new species of ornamental fish. This research has determined that the features of such industry include: high added values, long time for development, long earning period, R&D-oriented, under numerous restrictions and with less energy dependency. According to a literature review and profile of the company, the research found that Taiwan has achieved significant results in terms of genetic transformation and cloning. Taiwan is one of the best countries when it comes to research and development abilities. Glowing fish play an important role in the upgrading of the ornamental fish industry. Also, the government encourages investment in biotechnology industries. In all biotechnology industries, agricultural biotechnology has lower risks and faster output than other medical biotechnology products, and hence agricultural biotechnology has greater development potential. The research suggests that the ornamental fish dealers enhance the participation to industry ¡Vacademy cooperation, cooperating with Academia Sinica, Fisheries Research institute, and the technological platform of ornamental fish genetic engineering industry, to accelerate the schedule of the research and the development of new species. In addition, facing the doubts related to Living Modified Organisms (LMO) in the international community, ornamental fish producers need to develop new technologies to sterilize genetically modified ornamental fish and create a safety evaluation and certification system for genetic-transformation of aqua-cultural animals to avoid or minimize any possible damage of LMO to the environment.

Assessment of an environmentally-friendly method of ornamental fishing associated with revenues of fishers in Tejakula sub-district, Buleleng region, Bali, Indonesia

Pasaribu-Guzina, Stella Sherley Miryam 17 September 2013 (has links)
This study examined the impact of reformed fishing and reef management practices in a community-based marine ornamental fishery in Tejakula sub-district, Bali, Indonesia, on the development of effective community-based natural resource management. With the absence of cyanide fishing for one decade, the coral reef condition has improved from 26% of area coverage to 53%. T-test result shows that there is no significant difference in individual fishing revenue and a considerable decrease in total fishery revenue. The fishers have benefited in resource conservation and a 73% decrease in fishing costs. The overall number of ornamental fishers has declined, due to social pressure, a smaller overall fishing space because of No Take Zones (NTZ), and fewer orders for ornamental fish.Environmental education for local community members is critical to maintain adherence to the reformed method of fishing. Clear definition of the NTZS policy should be acknowledged to avoid recurring conflict among stakeholders.

Accleration of fish sauce fermentation using proteolytic enzymes

Chaveesuk, Ravipim January 1991 (has links)
First grade and second grade Nampla, commercially produced Thai fish sauces, were analyzed for their chemical and microbiological composition. First grade commercially produced Nampla contained higher amounts of total nitrogen, formol nitrogen, free and total amino acids compared to second grade sauce. Most of the essential amino acids were present in both grades of sauces. Low microbial counts of halotolerant microorganisms were observed in both sauces. The use of trypsin and chymotrypsin to accelerate the rate of fish sauce fermentation produced from herring, one of the underutilized fish species in Quebec, was investigated. Results showed that supplementation with trypsin and chymotrypsin increased significantly the rate of proteolysis, the amounts of total nitrogen, formol nitrogen and free amino acids in the final fish sauces (p 0.05).

Population trends of major near-shore fish species in Indiana waters of Lake Michigan

Sapp, Shawn A. January 1999 (has links)
The purpose of this research was to determine population trends of major nearshore fish species in Indiana waters of Lake Michigan from 1984 to 1998 to gain insight into species dynamics. Index trawl samples were collected twice monthly from June through August at three locations. Trends of catch-per-unit-effort (CPUE) were investigated for the most abundant species: yellow perch (Perca flavescens), alewife (Alosa pseudoharengus), spottail shiner (Notropis hudsonius), rainbow smelt (Osmerus mord iz), and bloater (Coregonus hoyi). Trawl catch of yellow perch, alewife, and spottail shiners at sites M, K, and G were strongly correlated suggesting similar fluctuations. Young-of-the-year trawl catch revealed that insight to population dynamics of species was not always reliable. Trawl CPUE of > age 1 fish provided insight to dynamics of the major species at all sample locations with strong trend similarities between sites. No strong major species interactions were found using simple linear correlations. / Department of Biology
