Predicting food consumption of fish populations as functions of mortality, food type, morphometrics, temperature and salinity
(1998)Type: Journal ArticleA large data set of relative food-consumption estimates (Q/B) of marine and freshwater fish populations (n = 108 populations, 38 species) is documented and used to derive a predictive model for Q/B, using asymptotic weight, ... -
Transgene expressions in seabass (Lates calcarifer) following muscular injection of plasmid DNA: a strategy for vaccine development?
(1998)Type: Journal ArticleMuscular injection has become one of the direct methods for transferring foreign DNA into organisms. The technique has been recently introduced in the development of vaccines and gene therapy. Vaccine development, in ... -
Molecular probes and polymerase chain reaction (PCR) -based kits for diagnosis of shrimp diseases
(1998)Type: Journal ArticleTechnology for effective and fast diagnosis of animal diseases is essential for developing aquaculture management strategies. This paper reviews the conventional techniques for shrimp disease diagnosis and discusses the ... -
Length-weight relationship of some marine fish species in Reunion Island, Indian Ocean
(1998)Type: Journal ArticleThe length-weight relationship of 29 marine fish species form Reunion Island (SW Indian Ocean) belonging to 14 families were computed. Data from 5,340 individuals were used for this purpose. Fish were sampled using different ... -
Observations on gillnet catches of Kariba tilapia, Oreochromis mortimeri from Bumi Basin of Lake Kariba, Zimbabwe
(1998)Type: Journal ArticleGillnet catches of Oreochromis mortimeri (Trewavas) were studied in the Bumi Basin of Lake Kariba in 1988 and 1989. Total length (TL) was positively correlated with standard length (SL). The linear relationship between TL ... -
Aquaculture: the last frontier for sustainable food security?
(1998)Type: Conference PaperFish has become a political commodity, thanks to its increasing scarcity and its high value. Aquaculture offers opportunities as the last frontier for sustaining the contribution of fish to food security. Asia is at the ... -
Effect of fishpond input on pond mud nutrient levels in integrated crop-fish culture resource recycling
(1998)Type: ReportThe success of aquaculture among small holder farmers in Malawi, depends on the use of the available on-farm resources. Commercial fish feeds are currently not available. Fish ponds open possibility for recycling of waste ... -
Integrated poultry-fish farming: a way to increase productivity benefits
(1998)Type: Book ChapterThe integration of aquaculture with poultry results in a more efficient use of resources than is possible with aquacul-ture farming alone. Other benefits of diversification include a reduction in the risk of total crop ... -
Efforts to save the marine environment in Tanzania
(1998)Type: Journal ArticleThe Tanzanian marine environment has been under threat for quite a long time now due to human activities. With the establishment of the Marine Parks and Reserve Act in 1994, several areas have been earmarked as marine ... -
Promotion of substrate based microbial biofilm in ponds: a low cost technology to boost fish production
(1998)Type: Journal ArticleMicrobial biofilms have been found to increase fish production in ponds by increasing heterotrophic production through periphyton proliferation on available substrates. In this paper, the role of substrate based microbial ... -
Growth and survival of the giant clams, Tridacna derasa, T. maxima and T. crocea, at village farms in the Solomon Islands
(1998)Type: Journal ArticleIn this study, the authors report the results of large-scale grow-out trials for T. crocea, T. maxima and T. derasa at 11 sites in the Solomon Islands over 2 years. During these experiments, we evaluated the influence of ... -
Farming experiments and transfer of technology of bivalve culture along the southwest coast of India
(1998)Type: Journal ArticleThe Central Marine Fisheries Research Institute (CMFRI) in India developed bivalve farming technologies in the 1970s, but these were not widely adopted at the time. In 1993, CMFRI undertook an action research program to ... -
Genetic improvement of farmed tilapias: growth performance in a complete diallel cross experiment with eight strains of Oreochromis niloticus
(1998)Type: Journal ArticleA complete diallel cross experiment was carried out with eight strains of Nile tilapia (Oreochromis niloticus). The strains represented four wild populations collected from various locations in Africa and four populations ... -
Growth and length-weight parameters of Pacific mackerel (Scomber japonicus) in the Gulf of Guayaquil, Ecuador
(1999)Type: Journal ArticleThe seasonally oscillating growth parameters and length-weight relationships for Scomber japonicus caught in the Gulf of Guayaquil, Ecuador, were determined based on length-frequency data from 1989 to 1996, using the FiSAT ... -
Integration of aquaculture into the farming systems of the floodprone ecosystems of Bangladesh: an evaluation of adoption and impact
(1999)Type: ReportThis report presents the results of studies undertaken for incorporating low-external input aquaculture practices into the farming systems of a complex floodprone ecosystem in Bangladesh and the impacts of integration on ... -
