introduction high-producing dairy cows require large amounts of concentrates that are rich in energy and crude protein to meet their nutrient requirements. cereal grains and oil supplements are commonly used for increasing energy density of diets fed to high-producing dairy cows. dietary grain source (barley vs. corn) and oil supplement (soybean- vs. fish oil) resulted in varied dry matter inta...

Aquaponics is a promising cultivation technique for combined production of crops and fish, on the condition tackling certain nutrients deficiencies. The aim present study was to examine limitations imposed by system spinach (Spinacia oleracea) growth functional performance identify minimum nutrient supplementation their optimization. Spinach co-cultivated with red tilapia under three treatments...

The estuarine genus Pfiesteria has received considerable attention since it was first identified and proposed to be the causative agent of fish kills along the mid-Atlantic coast in 1992. The presumption has been that the mechanism of fish death is by release of one or more toxins by the dinoflagellate. In this report, we challenge the notion that Pfiesteria species produce ichthyotoxins. Speci...

Title of Document: A NOVEL APPROACH TO PRODUCE ORGANIC FERTILIZER FROM FISH SCRAPS Armin Norouzi, Master of Science, 2013 Directed By: Y. Martin Lo, Ph.D., Department of Nutrition and Food Science A process was developed using an acidic system to hydrolyze fish protein, followed by a membrane-based separation process to purify and separate the desired liquid portion from the remaining solid pri...

Natural zeolite was used as a bed medium for plantation of lettuce seedlings and its effects on growth and chemical composition of red tilapia and lettuce were investigated in a pisciponic system. The place of study was the Aquatic Resources Technology Laboratory, Faculty of Agriculture, at the University Putra Malaysia, in 2002. The mean individual weight and biomass of fish in the treatment w...

The Fish Barcode of Life Initiative (FISH-BOL) is a concerted global research project launched in 2005, with the goal to collect and assemble standardized DNA barcode sequences and associated voucher provenance data in a curated reference sequence library to aid the molecular identification of all fish species. This article is a detailed progress report (July 2010) on the number of fish species...

The antimicrobial triclocarban (TCC) is frequently found in personal care products and commonly observed in surface waters and sediments. Due to its long environmental persistence TCC accumulates in sewage sludge. It also shows a high unintended biological activity as a potent inhibitor of the soluble epoxide hydrolase (sEH) and may be an endocrine disruptor. In this study, we investigated bioc...

Fish is the primary dietary source of omega-3 long-chain polyunsaturated fatty acids, which are necessary for healthy prenatal development and linked to reducing cardiovascular disease risk. The type and quantity of seafood that individuals choose to eat can impact both their health and the long-term sustainability of the world’s fisheries. An interdisciplinary team of researchers wants consume...

Over the last decades, views on fisheries management have oscillated between alarm and trust in management progress. The predominant policy for remedying the world fishing crisis aims at maximum sustainable yield (MSY) by adjusting gear selectivity and fishing effort. Here we report a case study on how striving for higher yields from the Eastern Baltic cod stock by increasing selectivity has be...
