Ahstracr.-This study evaluated the effects of dietary protein concentration (26, 28, and 32%) on growth. feed efficiency, processing yield, and body composition of USDA 103 and Mississippi “normal” (MN) strains of channel catfish raised in ponds. Fingerling channel catfish (average weight = 32.5 and 47.3 g/fish for USDA103 and MN strains, respectively) were stocked into 24 0.04-ha ponds (12 pon...

Today, fishing is the major source of mortality in many harvested fish stocks. The new high fishing mortality regime may induce evolutionary change in the harvested population, because the currently observed life-history patterns in fish stocks presumably reflect adaptation to past mortality regimes. Changes in these life-history patterns are likely to have an influence on, for example, the sus...

—Fisheries models often assume that discarded undersized fish and target species will survive and contribute to future recruitment and yield. If smaller fish are more susceptible to capture stressors than larger fish, then the assumption that smaller discards would contribute to recruitment may not be true. We tested the hypothesis that small sablefish Anoplopoma fimbria show more behavioral im...

Rice and fish are common staple foods in many parts of Asia, Africa, and Latin America. The cultivation of fish in paddy fields has proven to be highly productive. Simultaneous rice and fish cultures can be accomplished with l i t t l e extra effort and is economically feasible and practical. Fish enhance rice yield through predation of insect pests, reduce aquatic vascular plant and algal grow...

Gelatin isolated from limed split wastes can be a high value product due to its special characteristics and has many potential future applications in Food, functional additives, Food and pharmaceutical industries. Concentrations of sodium hydroxide, sulfuric and acetic acids used in processing gelatin from Narrow barred, Carcharhinus Leucas, Siganus Sutor and Indo Pacific king mackerel skins af...

Fish species are diverse. For example, some exhibit early maturation while others delay maturation, some adopt semelparous reproductive strategies while others are iteroparous, and some are long-lived and others short-lived. The diversity is likely to have profound effects on fish population dynamics, which in turn has implications for fisheries management. In this study, a simple density-depen...

estimation of fillet biochemical composition and processing yield is primary needs for fish processing. present study was aimed to investigate for determining fillet biochemical composition and processing yield of bighead (hypophthalmichthys nobilis) for nutritional labeling and economical estimation of its products by regression equations. for this purpose 55 specimen of bighead were applied i...

background and objectives: mortality is highly variable within population of cultured fish due to virulent bacteria causing fish septicemia. the use of nano-silver marine fungal chitosan as antibiotic synergisers could be an alternative in the treatment of sepsis fish pathogens. materials and methods: different bulk chitosan solutions were prepared from the mycelia of four marine fungi ( asperg...
