A preliminary study on the protein requirement of Chanos chanos (Forskal) fry in a controlled environment

Growth rate of fish appeared to be related to the levels of the protein in the diet up to 40%. Fish fed diets containing 50 and 60% grew slower than those fed 40%, and the optimum level appears to be 40% when fed to fry at a rate of 10% of body weight. Best feed conversion of 1.96 was also obtained from the 40% protein diet. Mean survival rates were low in all treatments, but highest for the 40% protein diet. The competition of 5 isocaloric experimental diets containing various levels of protein are tabulated, as are weight gains, diet conversions and survival rates for milkfish fry fed various dietary levels of protein. Growth curves for milkfish fry are shown, and the relationship between weight gains of milkfish fry and the dietary levels of protein are illustrated.

Fisheries, marine environment, and integrated coastal management policy processes, content and implementation in the BOBLME countries: regional synthesis and country questionnaires

This paper examines policy processes, policy trends and policy implementation with regards to capture fisheries, the marine environment and Integrated Coastal Management (ICM) in BOBLME countries. Individual country information was analyzed to generate a regional synthesis.

Shrimp culture and the environment

The paper discusses the impacts of shrimp culture to the environment in some countries in Asia. Specifically, it highlights the land requirements suitable for shrimp farming and the impacts of shrimp culture on mangroves. The positive effects of mangroves such as its filtering capacity and as a protective buffer are also discussed.

Go for environment friendly aquaculture

The article presents environment friendly aquaculture practices such as semi-intensive aquaculture, the culture of native species, the selection of proper sites for aquaculture facilities, the conduct of thorough, honest socioeconomic and ecological impact assessment before proceeding with the implementation, and the practice and promotion of proper pond/cage/tank preparation and management among others.

Enriched environment experience overcomes the memory deficits and depressive-like behavior induced by early life stress

Stress in early life is believed to cause cognitive and affective disorders, and to disrupt hippocampal synaptic plasticity in adolescence into adult, but it is unclear whether exposure to enriched environment (EE) can overcome these effects. Here, we rep

Enriched environment treatment restores impaired hippocampal synaptic plasticity and cognitive deficits induced by prenatal chronic stress

Prenatal stress can cause long-term effects on cognitive functions in offspring. Hippocampal synaptic plasticity, believed to be the mechanism underlying certain types of learning and memory, and known to be sensitive to behavioral stress, can be changed
