Carp is a highly invasive, bottom-feeding fish which pollutes and dominates lakes by releasing harmful nutrients. Recently, biologists started studying carp behavior by tagging the fish with radio-emitters. The biologists search for and localize the radio-tagged fish manually using a GPS and a directional antenna. We are developing a novel robotic sensor system in which the human effort is repl...

OBJECTIVE Public health messages to reduce Hg exposure for pregnant women have focused exclusively on advice on fish consumption to limit Hg exposure, with little account being taken of the positive contribution of fish to nutritional quality. The aim of the present review was to compare and contrast the content and presentation of national guidelines on fish consumption in pregnancy, and comme...

Fish are highly nutritious food items. In most countries, fish is one of the significant sources of animal protein and essential nutrients for the maintenance of health and protection from different types of diseases, such as blood pressure, cancer and heart stroke [1]. Sea food products reduce vulnerability to hunger by providing a complementary food source when other food sources, such as agr...

A mechanistic understanding of the effects of nutrient enrichment in lotic systems has been advanced over the last two decades such that identification of management thresholds for the prevention of eutrophication is now possible. This study describes relationships among primary nutrients (phosphorus and nitrogen), benthic chlorophyll a concentrations, daily dissolved oxygen (DO) concentrations...

The phosphorus and nitrogen discharge via effluent of intensive trout farming system was quantified through the use of environmental indicators. The nutrient loads, the mass balance, the estimated amount of nutrients in feed and the amount of nutrients converted in fish biomass were calculated based on the concentrations of phosphorus (P) and nitrogen (N) in the feed and in the water. Of the of...

Wild wrasses are used for delousing of farmed salmon but increasing demands have prompted the salmon industry to develop cultures of Ballan wrasse. One of the bottlenecks has been nutrition and feed intake in the juvenile phase, while broodstock nutrition is considered critical for production of viable offspring. The present study was aimed at developing functioning ongrowing and broodstock die...

Fish is a major source of nutrients critical for brain development during early life. The importance of childhood fish consumption is supported by several studies reporting associations of n-3 polyunsaturated fatty acid (n-3 PUFA) supplementation with better behavior and school performance. However, fish may have a different effect than n-3 PUFA alone due to the neurotoxic effects of methylmerc...

Point and nonpoint sources of nutrients, sediments, metals, and organic compounds from industrial, agricultural, and urban land uses are important water-quality issues in the Study Unit. Degradation of streams, including the loss of riparian habitat, reduction in fish populations, loss of habitat for bottom-dwelling organisms, eutrophication, and deterioration of the sanitary quality of streams...
