Common carp (Cyprinus carpio) germplasm were sourced from Bauchi and Ibadan aimed at studying their hatchability from the various intraspecific crosses and effect of frequencies of feeding on stocking density of Carp fry. Both male and female were injected with Ovaprim at 0.5ml/kg body weight intramuscularly at a single dose. The number of eggs in 1 gram mass was determined, Fertilization rate and percentage of hatchability were calculated. One hundred and eighty (180) fry of Cyprinus carpio were randomly picked and distributed in nine bowls of 50 litres at three stocking densities with replicates for each treatment. The frequencies of feeding were in these order; Ten (10) fry per bowl of 50 litres were fed twice a day, Twenty ( 20) fry per bowl of 50 litres were fed four times a day, Thirty (30) fry per bowl of 50 litres were fed six times a day, respectively for 8 weeks with 30gm of 0.2mm Coppens starter diet. The Ib♀ x Ba♂ cross had the highest hatchability though highest fertilization rate was recorded by Ba♀ X Ba♂ cross. The various crosses had above 50% hatchability, though percentagehatchability differed significantly at (P <0.05). While the growth pattern of the different stocking densities at different feeding frequencies differed significantly (p<0.05). The intra specific crossing of different sexes from the two sources gave a higher yield as can be seen with the IB♀ x BA♂. Whereas carp fry stocked at a lower stocking density with a fewer feeding frequency had best growth.

The study investigated the morphometric and meristic characterization of Common carp (Cyprinus carpio) sourced from Jos Bauchi and Ibadan (Nigeria). In comparing the morphometric and meristic characters one hundred and eighty (180) adult Common carp, Cyprinus carpio were used. Twenty four (24) morphometric and six (6) meristic characters were studied. Measurements of the morphometric features were taken to the nearest centimeter by means of a measuring board, measuring rule, pair of dividers for the length, while the weight was taken by means of a weighing scale (salter scale) to the nearest gram. ANOVA, multivariate technique principal component analysis (PCA) and discriminant function analysis were also applied to the transformed morphometric data to; classify the fish into one or several mutually exclusive groups. The Morphometric study indicated that seven parameters did not differ significantly (p>0.05) between Jos (male and female), and Bauchi (male and Female) strains. The parameters are the body depth, caudal fin length, pectoral fin height, standard weight, pre dorsal distance, eye diameter and body weight. In the meristic count, only the dorsal fin spine did not differ significantly (p >0.05) among the Jos, Bauchi, and Ibadan strains in all sexes. The study revealed that there was a genetic distance between male and female Carp sourced from Ibadan and that of Jos and Bauchi, where as male and female Carp from Jos and Bauchi showed genetic closeness.

The aim of the present study was to compare dressing percentages, with relation to sex, of three bisexual groups of hybrid carp, i.e. Hungarian mirror carp and Northern mirror carp (M2 × M72), the hybrid line of Přerov scaly carp and Northern mirror carp (PS × M72), the hybrid line of P.erov scaly carp and Ropsha scaly carp (PS × ROP), and the pure line of P.erov scaly carp (PS) in harvest size (K3). There were practically no differences in growth variables of male and female carp between the pure line PS carp and M2 × M72 and PS × ROP hybrids. Statistically significant differences in some variables between sexes were found in the scaly hybrid line PS × M72. Females in that group had significantly higher growth rates (TL and SL by 4.08% and 4.52%, respectively; p < 0.05), and their weight variables were also higher (FW, CW and FilletWabs by 11.37%, 13.70% and 14.83%, respectively; p < 0.05 and p < 0.01). The weight of gonads of male carp from all the groups studied was significantly higher (p < 0.01) than that of ovaries of female carp (or, rather, the GSI of male carp was higher).
