This study was carried out to determine some reproductive characteristics of the fantail goldfish Carassius auratus females (standard length 69-224 mm. and total weight 21.1- 255.35 g.) from rearing ponds in Basrah province, Southern Iraq. Standard length, weight, gonad absolute fecundity, relative gonadosomatic index (GSI) egg diameter were determined October 2010 April 2011 77 females. Result...

monetary compensation for human eggs used in research is a controversial issue and raises major concerns about women’s health and rights, including the potential of exploitation and undue inducement. human eggs are needed for various types of studies and without payment, it would be impossible to procure sufficient eggs for vital research. therefore, a solution seems necessary to prevent exploi...

this experiment was conducted to evaluate the effects of different levels of portulaca oleracea (po),medicinal plant, on performance, egg traits, blood biochemical and immunity parameters of laying hens. one hundred eighty hi-line (w-36 strain) mature laying hens 65 up to 76 weeks of age were allotted in a completely randomized design consisting of 5 treatments and 3 replicates (12 birds per re...

High exploitation of the blue swimming crab (Portunus pelagicus) has significantly reduced its wild populations. The domestication process this species been started; however, breeding program not yet successful. Therefore, study aimed to examine reproduction performance intraspecific hybrids from Sorong (Papua) and Barru (South Sulawesi), Indonesia. P. pelagicus a bigger size, while better perf...

Quail eggs are known to be highly nutritious. In the first study, nutritional and mineral composition of quail was evaluated by determining proportion moisture, total ash, lipids, nitrogen, crude protein carbohydrate in egg. The second phase determine role bone healing. Freshly laid Japanese were purchased from a research institute Plateau state, Nigeria. Five randomly selected used for evaluat...

We examined the effect of constant water temperature throughout year on gametogenesis, spawning success and egg/sperm/embryo quality in meagre (Argyrosomus regius). Two broodstocks were exposed to simulated natural photoperiod, andeither attenuated seasonal (SeasT, 16.4 19.6ºC) or relatively (CoT, 19.4 ± 0.6ºC).In period (May), 4 couples per group induced spawn with gonadotropin releasing hormo...

Two specimens of the butterfly blenny, Blennius ocellaris, were caught off coast Ordu (Black Sea, Turkey) in April 2021 by trammel net. The aim this paper is to further document occurrence and distribution blenny for Black Sea Turkish marine ichthyofauna provide first morphometric, reproduction, genetic data on species fauna species. Some morphometric meristic characters measured presented as p...

this experiment was carried out to study the effects of different levels of canola meal of different fat sources on the egg quality, performance as well egg yolk cholesterol during the first 12 weeks of age in laying hens (hy-line w-36). throughout the experiment a total of 432 hens were employed in a completely randomized design in a factorial arrangement of 3×4, with three levels of canola me...
