The success of intensive striped catfish (Pangasius hypophthalmus) cultivation requires quality feed that contains not only protein according to fish needs but also a complete essential amino acid profile support the growth. One solution overcome this problem is done through addition lysine in commercial. This study aimed examine effect on efficiency utilization, growth and body composition (P....

Background: Sesbania aculeata leaf are rich in nutrients which makes it a potential ingredient fish feed preparation. Solid-state fermentation (SSF) process of enhanced nutrient content and reduced antinutritional factors. This experiment was conducted to optimize inclusion raw fermented S. meal (RSLM FSLM) the diet Labeo rohita at fingerling stage different level. Methods: Nine isonitrogenous ...

Generally, cultured fish are suitable in media with a pH of around 7, like mountainous river and borehole water. However, peat water is known low pH. It not for culture, especially fingerlings. This study was conducted to examine the survival African catfish fingerling (Clarias gariepinus) mixture different pHs. Survival test as subject applied bioassay method, LC50-96 hours. Peat agent arrange...

the aim of this study was determination of abundance and biodiversity of zooplankton community at integrated fish culture of grower and fingerling fishes at east of golestan province, gonbade kavous city. sampling was done monthly at 6 ponds during one season culture from june to november 2011. during six month study period, 4 groups and 27 genuses were identified. between recorded groups, 12 g...

All organisms are probably exposed to different types of electromagnetic fields (EMFs). This study is an attempt to evaluate the effect of extremely low-frequency EMFs (50 Hz) on some growth parameters and survival rate of common carp fingerling. The fry (n = 120, averaged 16.76 ± 0.88 g in initial weight) was exposed to ELF-EMF at four intensities of 0.1, 0.5, 1 and 2 mT only once for 2 h and ...

Estimating the catfish aquaculture production losses that can be attributed to double-crested cormorants (Phalacrocorax auritus) has proved problematic because knowledge of the distribution of cormorants on catfish aquaculture is lacking. We evaluated use versus availability of various production pond types and landscape-scale factors affecting the distribution of cormorants on channel catfish ...

Bream (Abramis brama, Berg, 1949; Family: Cyprinidae) is commercially valuable fish in the Caspian Sea fishing industry. Iranian Fisheries Organization annually produces and release up to 19 million Bream fries size for recruiting of this species. Its fries are mostly released into the Anzali wetland with 4 ppt salinity. Meanwhile, they sometimes are released into Sefidrood River (0.5 ppt), Sef...
