A 12-week growth experiment was conducted to evaluate the suitability of Azolla cristata as a fish meal (FM) substitute in diets for Cyprinus carpio var. communis fingerlings. Six iso-nitrogenous and isocaloric (16.17 kJ/g GE) were formulated contain 42% crude protein each treatment had three replicates. The mean initial weight 3.4 ± 0.2 g. Graded levels A. 0, 10, 20, 30, 40, 50% fed triplicate...

Abstract This study was conducted to evaluate the efficiency of isolates probiotic bacteria Lactobacillus acidophilus 4453 and Streptococcus thermophilus 5935 on blood parameters innate immunity common carp fingerlings which had initial body weight attained (44±0.69) g. A total 72 fish were used randomly divided into 4 treatments with 3 replicates (6 per replicate). An experimental diet prepare...

A 60-day feeding trial was conducted to delineate the effect of three dietary levels of gelatinized starch on fatty acid profiles and RNA and DNA contents of fingerlings of the Indian major carp, Labeo rohita, reared at ambient water temperature (26±0.8°C) or 32°C. Two hundred and sixteen fingerlings (6.5±0.3 g) were randomly distributed into six treatments in triplicate. Three semi-purified is...

Based on the nutrient requirement of blue gourami, Trichogaster trichopterus fingerlings as reported earlier, nine experimental diets with 350 g protein, 80-100 g lipid and 16-17 MJ digestible energy/kg diet were formulated using snail meat (D-1), freshwater fish processing waste (D-2), surimi by-product (D-3), chicken offal (D-4), earthworm (D-5), squid (D-6), mussel (T-7), chicken liver (T-8)...

In West Alabama, disease outbreaks in 2009 caused by Aeromonas hydrophila have led to an estimated loss of more than $3 million. In 2010, disease outbreak occurred again in West Alabama, causing losses of hundreds of thousands of pounds of market size channel catfish. During the 2010 disease outbreak in West Alabama, four isolates of A. hydrophila were cultured from the kidney tissues of diseas...

Aim : To study the acute toxicity of λ-cyhalothrin in freshwater fish Labeo rohita by determining the 96 hours lethal concentration 50 (96 hrs LC ) and behavioural patterns of exposed fish. 50 Materials and Methods: A total 270 fingerling size fish were used to determine the 96 hours lethal concentration 50 (96 hrs LC ) of λ-cyhalothrin as per the guideline of Organization for Economic Co-opera...

The Instituto de Investigaciones de la Amazonia Peruana (IIAP) is the leading governmental organization working in aquaculture and fisheries research in the Peruvian Amazon region. In addition, IIAP produces fingerlings, offers training courses, and works with nongovernmental organizations (NGOs) endeavoring to promote fish culture. This report summarizes fieldwork and survey results from rural...

The availability of O. niloticus fingerlings remains a problem in South Western Highland Agro-Ecological Zones. Most fish farmers produce only small sized fish probably because of inbreeding in Uganda. Brood stocks of Nile tilapia, Oreochromis niloticus L. were collected from Lakes Victoria, Kyoga and Kayumbu, a minor lake in SWHAEZ. The brood-stock were conditioned and bred. Fingerlings of F1 ...

This study used a two-phase feeding trial to determine the influence of selected dietary prebiotics and probiotics on growth performance, feed utilisation, and morphological changes in snakehead (Channa striata) fingerlings as well as the duration of these effects over a post-experimental period without supplementation. Triplicate groups of fish (22.46 ±0.17 g) were raised on six different trea...

Bacterial infection among the most common cultured mudfish Clarias gariepinus in Africa, has become a cause of concern, because it constitutes the largest economic loss in fish farms. In order to provide useful biological data of the pathogens for good management practices, samples were collected monthly between January 2008 and December 2009 in three monoculture nursery ponds, located in three...
