This study evaluated the suitability of canola oil as a source of supplemental dietary lipid for rainbow trout. Triplicate groups of the 30 fingerlings held under identical culture conditions were fed twice daily by iso-nitrogenous, iso-calorific and iso-lipidic diets for eight weeks. Experimental diets consisted of 30.3% protein, 18.7 kJg-1 energy and 16.7% lipid from fish oil (FO), canola oil...

Fluorescent in situ hybridization (FISH) was carried out using two different oligonucleotide probes speciÞ c for Pseudomonas spp. and Acinetobacter spp. These probes were tested against different organisms and were found to be highly speciÞ c. Sensitivity testing showed that the probes were able to detect as low as 103 CFU/mL. In addition, FISH was carried out directly on positive blood culture...

The objective of the study was to determine optimal density fingerlings Nile tilapia (Oreochromis niloticus) culture in floating cages with respect growth performance and know effect temperature on during winter period. Tilapia (mean weight 8.5 ± 0.36 g) were stocked at densities 120, 180 360 fish/m3 for 10 weeks. During culture, fish fed a diet contains 35% protein made peanut seed, cottonseed...

This study was conducted to identify the general conditions for the isolation and in vitro culture of ovary-derived cells in rockfish (Sebastes schlegeli). The effects of three different enzymes on cell retrieval from ovarian tissues were evaluated first, and then the ovary-dissociated cells were cultured under various culture conditions, with varying basal media and culture temperatures, addit...

The murrel fish, or Channa striata, is a precious freshwater resource. Several recent studies on the nutritional content and bioactive compounds of fish have been conducted. Based farm water conditions, C. focus this study but not only species with high protein content, can be estimated to value. average moisture Striata fillet 74.9 ± 0.87%, significant variation between diets tested. Water sal...

As in many parts of the world, aquaculture production in the Mediterranean has been expanding rapidly over recent years (Basurco & Lovatelli, 2005). The continuous decline of ocean fisheries stocks has provided impetus for rapid growth in aquaculture. Global production of farm fish has more than doubled in the past 20 years with the growing demands of an expanding population, and it seems that ...

Six triploid individuals were found in a full-sib family of 11 adult rainbow trout (Salmo gairdneri) from a domesticated hatchery stock. The triploid individuals were normal in size and external appearance, had underdeveloped gonads, and showed no evidence of 3n/2n chimerism or mosaicism. XXY triploids were males, suggesting that the Y chromosome is male determining in trout. Because they may a...

The present study was undertaken to determine the prevalence of Listeria monocytogenes in selected raw materials and food products of animal origin in Poland. In total, 1118 fish and fish products, and 2172 meat and meat products samples were examined by using ISO culture method. Out of 478 pork samples examined 45 (9.41%) contained L. monocytogenes. Out of the 317 samples of beef the microorga...
