BACKGROUND Fish processing is a common economic activity in Southern Africa. The aim of this study was to determine the prevalence and host determinants of allergic symptoms, allergic sensitization, bronchial hyper-responsiveness and asthma among workers processing saltwater fish. METHODS A cross-sectional study was conducted on 594 currently employed workers in two processing plants involved...

Plant proteins are plausible fishmeal substitutes but are deficient in some essential amino acids (EAA) like lysine and methionine. Combination of different plant proteins with complimentary EAA could be useful alternative. Bambaranut (Voandzeia subterranea) contains high amount of lysine while methionine is in sesame seed (Sesamum indicum). This experiment tested effects of combining sesame se...

Dietary supplementation with hydrolysates has been suggested to influence muscle protein synthesis and fish growth. This study assessed the impact of including 3% swine blood (BH) in a plant-based diet on cellularity expression molecular markers related fibre proliferation hypertrophic growth European seabass. Three BH fractions were obtained by two different processes, autohydrolysis (AH-H) en...

An eight-week feeding trial was performed to evaluate the effects of yeast hydrolysate (YH) supplementation in a low-fishmeal diet on growth, immune responses, intestinal histology and disease resistance whiteleg shrimp (Litopenaeus vannamei). Five experimental diets were produced by supplementing YH at 0 (CON), 0.5 (YH0.5), 1 (YH1), 2 (YH2) 4 (YH4) % basal containing 10% fishmeal compared with...

A trial was conducted to investigate the potential of the progeny of feral goats x selected, cashmere producing, bucks to utilize high levels of supplementary protein in order to increase cashmere yield. A basal diet (approx. 10 per cent crude protein (CP) and 12 MJ metabolisable energy (ME)) was fed on its own or supplemented in the following ways: urea (1.5 per cent), fishmeal (5, 10 and 15 p...

At present, small pelagic forage fish species (includes anchovies, herring, mackerel, sardines, etc.) represent the largest landed species group in capture fisheries (27.3 million t or 29.7% of total capture fisheries landings in 2006). They also currently constitute the major species group actively fished and targeted for nonfood uses, including reduction into fishmeal and fish oil for use wit...

Most of world’s fish and seafood are produced by aquaculture, which is one the biggest contributors to food security. The substantial increase in prices conventional feed ingredients over-exploitation natural resources some constraints aquaculture production. To overcome this stress, different approaches techniques used, among use non-conventional sector most recent approach. Different such as ...
