Antibiotics and anabolic steroid growth promoters usage have facilitated the efficient production of poultry, allowing the consumer to purchase, at a reasonable cost, high quality meat and eggs. Although these uses benefit all involved, unfortunately, the edible poultry tissues had harmful concentrations of drug residues. Therefore, this study was carried out on one hundred randomly collected f...

Understanding the genetic basis of variation in traits related to growth and fillet quality in Atlantic salmon is of importance to the aquaculture industry. Several growth-related QTL have been identified via the application of genetic markers. The IGF1 gene is considered a highly conserved and crucial growth-regulating gene in salmonid species. However, the association between polymorphisms in...

Lactic acid bacteria (LAB) have been extensively explored as potential biopreservants. They could produce substances with antimicrobial properties such bacteriocins and organic acids which can also be the cause of antagonistic activity shown by LAB. Thus, objective this study is to assess LAB isolated from fermented Oreochromis niloticus against foodborne pathogens determine a surface decontami...

Accurate prediction of meat yield in live animals may allow more efficient genetic improvement of meat yield in farm-raised catfish. An initial trial with 30 channel catfish demonstrated significant correlations among weight-adjusted residuals for muscle area measured from transverse ultrasound images and transverse sections at five locations along the trunk musculature (r = 0.30 to 0.70). Rela...

Increase in demand of fish from Lake Victoria region has created gaps in local fish supplies and this raises concern since there are reports of limited animal-source food consumption plus protein and micronutrients deficiencies in this region. To fill the gap, less-preferred pelagic fish species such as Mukene (Rastreneobola argentea) and by-products from filleting Nile perch (Lates niloticus),...

Growth, feed conversion ratio and fillet composition of rainbow trout (initial weight of 9.99±0.109)were investigated in a 6x2 factorial design experiment employing two levels of digestible energy (DE) (2900 and 3500kcal.kg-1) and six feeding rates (1.0%, 2.0%, 3.0%, 4.0%,5.0% of the body weight,(BW) day-1 and to satiation) for 60 days. Specific growth rate (SGR) was highest at 5.0% rati...

Concentrations of Ni, V, Pb and Cu were determined in bottom sediments and liver, gills and fillet of Euryglossa orientalis and Chirocentrus nudus along the Bahrekan Bay in the Northwest part of the Persian Gulf in Iran. Sediment samples and fish species were collected during winter 2013 and spring 2014. Heavy metal analysis was performed by atomic absorption spectrophotometer. Results showed t...
