Ž . The use of a co-extruded soybean poultry by-product meal CEPM and flashed dried poultry Ž . by-product meal FD-PBM was evaluated as replacements for fish meal in a practical diet formulated to contain 32% crude protein and 8% lipid. Each meal was substituted for menhaden Ž fish meal on an iso-nitrogenous basis and offered to juvenile Litopenaeus Õannamei mean initial . Ž wt."S.D., 0.37"0.01...

Mixed rearing of tilapia (GIFT; Genetically Improved Farmed Tilapia) with shrimp (Penaeus monodon) in brackishwater rice-shrimp system was assessed for its impact on dry season's shrimp production. The experiment was conducted in pre-selected farmer's field located at Paikgacha Upazila of Khulna district and designed with three different densities (treatment) of GIFT, viz, 0.3, 0.4 and 0.5/m2 w...

The co-culture of juvenile sea cucumber Holothuria scabra (Jaeger), or 'sandfish', with juvenile blue shrimp Litopenaeus stylirostris (Stimpson) was tested by growing groups in co-culture and monoculture for 3 weeks in tanks with enriched sand substratum. Feed was supplied on trays, accessible only to shrimp. Survival of shrimp and sandfish was high in all treatments (73–100%). Growth of shrimp...

The paper explores the trade competitiveness of seven major shrimp exporting countries, namely Vietnam, China, Thailand, Ecuador, India, Indonesia and Mexico, to the USA. Specifically, we investigate whether the United States (US) antidumping petitions impact upon the bilateral revealed comparative advantage (RCA) indexes for each of the seven shrimp exporting countries with the USA. Monthly da...

The potential use of polychaete worms are as a dietary source protein, lipid, amino acids, and vitamins for aquaculture species also used alternative feeds fish meal oils. Many recent studies have been documented the nutritional benefits polychaetes species, their satisfactory food intake reproductive performance in brood stock.Most were hatcheries wild caught. commercial harvesting may leads t...

the aim of the current study was to evaluate the replacement effect of soybean meal (sbm) at different levels (0 as d1, 33 as d2, 67 as d3 and 100% as d4 based on crude protein (cp) content) by guar meal (gm) on ruminal gas production kinetics, ruminal digestibility and fermentation characteristics of a fattening diet for lambs. three experiments were conducted. the first experiment of 144-h in...

Within the past decade, viral diseases have emerged as serious economic impediments to successful shrimp farming in many of the shrimp-farming countries of the world. In the western hemisphere, the viral agents of Taura syndrome (TS) and infectious hypodermal and haematopoietic necrosis have caused serious disease epizootics throughout the shrimp-growing regions of the Americas and Hawaii, whil...

The total haemocyte count (THC), phenoloxidase activity, respiratory burst, superoxide dismutase (SOD) activity, phagocytic activity and clearance efficiency in response to pathogen Vibrio alginolyticus were measured when the white shrimp Litopenaeus vannamei (20.0+/-1.5 g) were injected individually with dopamine at 10(-8), 10(-7) and 10(-6)mol shrimp(-1), respectively. For the shrimp that rec...

Marine by-products can compose up to 70% of the total weight products from fisheries, most which are discarded. However, these rich in highly unsaturated fatty acids that not synthetized by marine animals produced aquaculture. Here, we used three (shrimp head, Catarina scallop viscera, and Pen shell viscera) produce lipid-rich (72.9–144.6 g/kg) meals were partially substitute commercial fishmea...

A study was conducted on culture practices of shrimp at farmers’ level in Bagerhat District. Investigation was based on a sample of 123 shrimp farmers from the seven Thanas (Fakirhat, Mollahat, Sadar, Rampal, Mongla, Chitalmari and Kachua) of the District, 73.17% farmers produced shrimp with white fishes. Farmers (54.47%) started to culture during 2000-2004 in this area. The culture period was ...
