During these last 20 years, many studies have focussed on the development of the digestive tract in marine fish larvae. Most of the studies aimed at acquiring knowledge on the optimal form of dietary supply for different nutrients, in order to formulate a compound diet able to totally replace live preys in the fish larvae feeding sequence. Consequently, most of the studies aimed at describing t...

aim : in this retrospective survey women with and without self-reported postpartum depression (ppd) were compared in regards to consumption-frequency of foods and supplements rich in nutrients beneficial to nervous system (ns) health, in regards to consumption-frequency of compounds which may counteract the effect of the above and in regards to nutritional support provided to them during a preg...

A field study in a boreal lake using a remotely operated vehicle equipped with a camera established that falling fish carcasses did not tend to be buried in sediments after deposition. Decomposition rates of fish carcasses in three boreal lakes were experimentally assessed at different depths. In shallow waters (between 0 and 4 m), decomposition was fast (half lives, t, ranging from 40 to 230 h...

Parasites depend on host-derived energy for growth and development, and so are potentially affected by the host's ability to acquire nutrients under competitive foraging scenarios. Although parasites might be expected to grow faster in hosts that are better at acquiring nutrients from natural ecosystems, it is also possible that the most competitive hosts are better at countering infections, if...

Enrichment of live foods by essential nutrients such as highly unsaturated fatty acids is an important tool for improvement of larval fish quality. In this study, nutritional effects of Artemia urmiana enriched by fish and plant oils on growth, survival rate, body compositions and resistance against thermal, salinity and hypoxic stresses in rainbow trout, Oncorhynchus mykiss were examined. Six ...

Omega-3 fatty acids contain high amounts of polyunsaturated fatty acids such as alpha-linoleic acid and the nutrients EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid), which have been shown to have a positive influence on human health by contributing to a reduced risk of heart disease and being essential for normal growth and development in adults. The problem we are facing is that th...

INTRODUCTION People worldwide depend upon daily fish consumption as a major source of protein and other nutrients. Fish are high in nutrients essential for normal brain development, but they also contain methylmercury (MeHg), a neurotoxicant. Our studies in a population consuming fish daily have indicated no consistent pattern of adverse associations between prenatal MeHg and children's develop...

An experiment was conducted in nine 200-m2 fertilized earthen ponds at the Asian Institute of Technology, Thailand, from January to September 2000. This experiment was designed to assess the recovery of pond mud nutrient by lotus (Nelumbo nucifera), to assess pond mud characteristics after lotus-fish co-culture, and to compare fish growth with and without lotus integration. There were three tre...

OBJECTIVE To investigate the gap between consumer perception and scientific evidence related to health benefits and safety risks from fish consumption. DESIGN Consumer perceptions from a cross-sectional survey in March 2003 in Belgium were compared with scientific evidence based on a literature review. METHOD A quota sampling procedure was used with age as quota control variable. Subjects c...

Low-trophic-level fish are a crucial source of long-chain (LC) omega-3 fatty acids for farmed fish and humans. Many farm-raised fish species have a clear need for these nutrients. Farmed fish deposit the LC omega-3s in their flesh and transfer them up the food chain. However, the content of LC omega-3s in farm-raised seafood continues to decline, while the content of shorter-chain plant-sourced...
