One important factor limiting tilapia culture development in Honduras as well as in the rest of the Central America is the lack of supply of fingerlings in sufficient quantity and quality. To assess the situation, we endeavored to obtain information and purchase fingerlings from every seed producer in Honduras. Sixteen tilapia fingerling producers were visited and interviewed during September 2...

An experiment was conducted to determine the growth performance of two Indian Major Carps Catla catla, and Cirrhinus mrigala fingerlings for period of 40 days. Nine experimental groups fed commercial pellet diet incorporated with three types of nutritional supplements (Gram positive lactobacil probiotic, Parry’s Spirulina and Vitamin C – Ascorbic acid) at different concentrations (2 %, 4 %, & 8...

CIRKOVIC, M., N. MILOSEVIC, M. MARKOVIC and A. POTKONJAK, 2010. Brain myxoboliasis of common carp. Bulg. J. Agric. Sci., 16: 263-265 The common carp (Cyprinus carpio) originating from Serbian fish ponds was examined for presence of Myxobolus encephalicus. The spores of M. encephalicus were present in blood vessels and meningeal layers. Its presence has been noted in 32-days old carp fingerlings...

After 50 days of pond culture fewer pike fingerlings (20 to 33 p. 100) were recovered from the mixing of two full-sib families than from isolated families. Growth and survival were influenced by the family effect. Environmental parameters, such as depth and extent of the banks, may also affect growth and survival. Our results indicated that isolating full-sib families and using small, shallow p...

The effect of dietary supplementation of commercial probiotics Bifilac® on growth of rohu, Labeo rohita fingerlings were evaluated. Experimental diet (ED) was supplemented with Bifilac® (3g/kg diet). Reference diet (RD) was not supplemented with Bifilac®. The feeding trial was conducted using L. rohita fingerlings (5.30±0.01 g) for 60 days in triplicates. The groups D1 and D2 were fed daily wit...

Vitamin C is essential for fish diets because many species cannot syntethize it. This vitamin is needed for bone and cartilage formation. Moreover, it acts as antioxidant and improve the immunological system. The present work investigated the effects of vitamin C diet supplementation to spotted sorubim (Pseudoplatystoma coruscans) fingerlings by frequency of bone and cartilage deformation. Asco...

Work under this investigation included farm survey, extension, and research components using both the CLSU research station and demonstration farms. An experiment was conducted for the determination of optimal stocking sizes, considering the growth and survival performance of various sizes of fingerlings along with economic factors. Size #22 sex-reversed nursery phase fingerlings of Nile tilapi...

木村雄一郎,本 田嘉秀:近 畿大 学理工学 部原子炉 工学科,東 大阪市,〒577 Comparative studies on the uptake and elimination of radionuclides, 6OCo, 131I, 137Cs, 141Ce and 106Ru by the advanced fry and the fingerlings of rainbow trout were conducted under laboratory conditions. The general patterns of uptake of 60Co, 131I, 114Ce, 106RuNO-nitro and -binuclear complexes by both the advanced fry and the fingerlings were similar t...

AIM The efficacy of dietary inclusion of various parts of mangosteen (Garcinia mangostana L.) extract on growth and hematological parameters of African catfish (Clarias gariepinus) fingerlings were investigated. MATERIAL AND METHODS Ninety six fingerlings were randomly distributed into each of ten 20L plastic aquaria. Each treatment groups consists of three replicates. Four experimental diets...

This study evaluated the suitability of canola and flaxseed oils as source of supplemental dietary lipid for fingerlings of rainbow trout. Triplicate groups of the 30 fingerlings were fed twice daily by iso-nitrogenous, and iso-calorific diets for 8 weeks. Experimental diets consisted of 30.2% protein, 18.6 kJ/g energy and 16.6% lipid from fish oil, canola oil, flaxseed oil, 1:1 blends of fish ...
