Spawning Induction System of Puntius javanicus using Common Carp as a Trigger

This study was carried out to determine the effect of induction using common carp as a trigger on spawning of Puntius javanicus. Mature male and female of Puntius javanicus were reared in outer of the hapa that contains mature male common carp, mature female common carp, or mature male and female common carp as a control. Common carp broodstock was injected or not injected by ovaprim. The result of study show that the use of male common carp injected or not injected by ovaprim could induced spawning of Puntius javanicus, without the release of sperm and eggs of common carp. Fertilization rate of Puntius javanicus eggs was high, reached of 91.4%, by using ovaprim-injected male common carp as trigger.

Induk ikan tawes jantan dan betina yang telah matang gonad ditempatkan di luar hapa tempat ikan mas jantan matang gonad, ikan mas betina matang gonad, atau sepasang ikan mas matang gonad sebagai perlakuan kontrol. Induk ikan mas disuntik atau tidak dengan ovaprim. Hasil penelitian menunjukkan bahwa penggunaan ikan mas yang disuntik ovaprim maupun tidak, dapat mengimbas ikan tawes untuk memijah meskipun tidak terjadi pengeluaran sperma dan telur ikan mas. Derajat pembuahan telur ikan tawes cukup tinggi, mencapai 91,4%, pada perlakuan induksi ikan mas jantan yang disuntik ovaprim.

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.

Sexual Characteristics

Secondary sexual characteristics such as softening and rounding of the abdomen as well as reddening and protrusion of the anal papilla and vent can be of help to breeders in selecting common carp (Cyprinus carpio) females prepared for propagation. To assess the reliability of this method, long-term data obtained on induced spawning of common carp at a large-scale fish hatchery were evaluated. The average spawning ratio of 2,620 females receiving hormonal injections was 79.8%. The average pseudogonadosomatic index (PGSI) calculated from data on the egg production of 2,086 females was 16.3 ± 5.87% (mean ± SD) for the same period. There was a correlation between fish weight and the time of induction determined by the breeder on the basis of external morphological characteristics. The similarity of the responses of females, including both spawning ratio and PGSI, among the different weight categories proved the reliability of this method for identification.

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.

Sexually Mature

Trawl-caught Portunus sanguinolentus were more abundant in oceanic than estuarine waters in south- east Queensland. In samples, males outnumbered females by 1.7 : 1. Males attained a larger size than females and, for a given carapace width, weighed more than females. The smallest sexually mature male and female crabs had carapace widths of 83 and 74 mm respectively. Crabs recruited to the sampled population throughout most of the year except during winter, when moulting activity was also limited. April-May was a major mating period, and it is postulated that mature female crabs moved into deeper oceanic water to spawn.

The Common

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).
