Feed the future aquaculture project: October 2011-Sept 2012

The Feed the Future Aquaculture project is a five year transformative investment in aquaculture focused on 20 southern districts in Barisal, Khulna and Dhaka divisions, Bangladesh. This report describes the achievements of FtF-Aquaculture project activities implemented during FY12. Some of the targets for production and associated income have not been achieved yet as a large share of the fish will be harvested after closing of the reporting period. However, on the basis of growth monitoring, indications are that production is on track to achieve the targets.

Feed the future aquaculture project: Draft quarterly progress report. Jan-March 2013

The Feed the Future Aquaculture project is a five year transformative investment in aquaculture focused on 20 southern districts in Barisal, Khulna and Dhaka divisions, Bangladesh, which started in October 2011. This report describes the achievements of FtF-Aquaculture project activities implemented during the 6th quarter (January to March 2013) along with cumulative progress on FtF indicators. Due to the seasonality of fish and shrimp production, which is out of sync with the project year, final harvesting of aquaculture production was completed in this quarter.

The Current status of aquaculture and aquafeed production in Bangladesh

Over the last decade, dramatic increases in the production of a variety of species from commercial aquaculture systems and sharp increases in per capita fish consumption have occurred in Bangladesh. This transition has been made possible by widespread adoption of semi-intensive and intensive production practices, accompanied by growth in the production and use of aquafeeds. Findings relating to the current status of aquaculture in Bangladesh have been reported in greater detail elsewhere.

Heterotrophic marine bacteria as supplementary feed for larval Penaeus monodon

The findings are presented of a study conducted to use autochthonously obtained, nonpathogenic heterotrophic marine bacteria as a substitute feed for microalgae in rearing larval Penaeus monodon. Eleven strains were isolated: Micrococcus (MCC), Staphylococcus, Streptococcus, Bacillus (two strains; BAC-1, BAC-2), Pseudomonas (two strains; PSM-1, PSM-2), Vibrio parahemolyticus, V. fluviatilis, Moraxella (MOR) and Flavobacterium. Six nonhemolytic strains were then chosen for the Penaeus monodon larval feed trials: BAC-1, BAC-2, PSM-1, PSM-2, MCC and MOR.

The evolution of body muscle composition of the African catfish (Clarias gariepinus) (Burchell 1822) .

Changes in body muscle composition of Clarias gariepinus were studied in fish reared from 1.08 g to 383 g mean body weight in a 201-day culture period. Changes in the amount of protein content, dry matter and ash free dry matter in the muscle tissue can be described as a function of body weight. The percentage of protein content was observed to be higher in bigger fish. Fat content was low throughout the fingerling stage. Specific growth rate decreased significantly at 400 g mean body weight (P<0.05) while feed conversion rate increased.

Evaluation of Nigella sativa L. (black seeds; barka), Allium sativum (garlic) & BIOGEN as a feed additives on growth performance and immunostimulants of Oreochromis niloticus fingerlings

A study was conducted to evaluate the effect of three immuno-stimulants (feed addit ives) on growth performance and immune system of 0. niloticus fingerlings. The aim of the present work is to highlight the effect of two local feed additives; black seed, garlic and a potent compound BIOGEN on the growth performance and immunostimulation of O. niloticus fingerlings.

Effect of pond supplemented with chicken manure on bacterial build up and its antimicrobial resistance, besides the quality and shelf-life of cultured Nile tilapia (Oreochromis niloticus)

Twelve thousand fries of Nile Tilapia (<i>Oreochromas niloticus</i>) were stocked in 6 ponds, three ponds were supplemented with chicken-manure and others with artificial diet. The Aeromonas. and <i>Pseudomonas spps.</i> were isolated from all ponds while the <i>Salmonella</i> and <i>Enterococcus spps.</i> were isolated from the manure supplemented ponds. As a General observation, the antimicrobial resistance of the isolated bacteria was high with oxytetracyclin, low with ciprofloxacin.

Effect of dietary supplementation of inulin and vitamin C on the growth, hematology, innate immunity, and resistance of Nile tilapia (Oreochromis niloticus)

The aim of the current study was to evaluate the in vivo potential effect of inulin (5 g kg-1) and Ascorbic acid (500 mg kg-1) on improving the performance as well as the immunity of Nile tilapia (Oreochromis niloticus). Their possible protective effect against an experimental challenge infection using A. hydrophila has been also investigated.
