Intraspecific Crossing

Intraspecific crossing of giant gouramy was done to get better hybrid population. This study was conducted to evaluate the hybrid vigour or heterotic value of the hybrids line, especially for growth rate character. Besides that, we want to know the effect of hybridization on performance of phenotypic variability. Two days post hatching age larvae of four populations i.e. Bastar and Blue-saphire strain, F-1 hybrid and F-1 hybrid reciprocal, were used in this experiment. All fish were reared in aquaria for 30 days period in indoor hatchery. The fish were fed with live food such as Moina and Daphnia for the first ten days, followed by Tubifex for the second ten days and finally, commercial feed were given until the end of the study. The collected data were total length, standard length, and body weight of each population. The results showed that the phenotypic variability of the hybrid population was higher than that of inbred population. Hybrid population from female of Bastar and male of Blue-saphire has better growth than both of its parents. Heterotic values of total length, standard length, and body weight of the hybrid population was 9.5%, 2.9%, and 15.6% respectively. Maternal effect was detected in hybrid population.

An experiment was conducted using 270 African catfish fingerlings to evaluate the effects ofdifferent feeding regimen on growth performance of the fish. The fish were hatched andreared to 12 weeks under similar condition before the commencement of the experiment thatlasted for 40 days. Feeding regimens included equally shared feed based on recommended of5% body weight, and equally spaced feed allocation at 6, 8 and 12 hourly intervals. Each ofthe three treatment groups comprised of six replicates of 15 fish per plastic tank. Body weight,and two linear measurements (total and standard length) were taken twice weekly on each ofthe fish in all the tanks and the respective length-weight relationship and condition factor (K)were computed. Weekly gain, final weight, average daily gain, absolute, relative, specific andmean growth rates for the three groups were evaluated and compared. Results showed that allparameters studied except final total length were significantly (P<.05) affected by feedingregimen. The coefficient of determination for all ANOVA had variable values for all growthparameter; Final Weight (83.11%), Absolute Growth Rate (79.19%), Final Total Length(61.30%), Final Standard Length (60.87%), Relative Growth Rate (38.68%), SpecificGrowth Rate (35.57%), Mean Growth Rate (32.23%) and Condition Factor (12.83%). The 6-hourly treatment group mostly had the highest values across all the parameters studied butwas not statistically different (P>.05) from the values obtained in the 8-hourly group.

AbstractThe aim of this study was to determine the growth features of European perch (Perca fluviatilis L., 1758) inhabiting Lake Ladik. A total of 858 individuals were caught. The total length and weight ranged from 8.2 to 27.5 cm and from 7.16 to 365.20 g, respectively. The age of the females ranged between 1 and 7 years and the age of the males ranged from 1 to 5 years. The female to male ratio was 1:0.19. The von Bertalanffy growth equation parameters were determined as L∞=41.27 cm, W∞=1251.40 g, K=0.10 (year−1), t0 (year)=−1.98 for all samples. Length-weight relationship was calculated as W=0.0047TL3.358 for all specimens. Length-length relationships (total length-standard length, total length-fork length, standard length-fork length) were highly significant (r2>0.98). The mean condition factor value was obtained as 1.28 for all fish. Condition factor showed statistically significant increase according to length classes.

Abstract Morphometric and meristic characters are very important for the identification of any fish specimen. The present study aims to describe the morphometric and meristic characters of the indigenous fish Crossocheilus diplochilus (Heckel) from Dal Lake. This fish is commonly known as Kashmir latia and is called tether locally. In the present study, the material analyzed was 70 specimens ranging in size from 6.9–13 cm (TL) with a mean length of 10.8 cm and a weight range of 3.2–24.0 g with a mean weight of 10.1 g. The parameters with the highest correlations with total length were standard length and fork length at 0.983 and 0.989, respectively. Correlation analysis showed that all morphometric characters changed proportionally as total length increased. The meristic counts analyzed in the present study remained constant in fish of different sizes indicating that they are independent of body size. The study of morphometric characters is very important to determine the growth rate of these fish, which, in turn, is required to properly manage its populations.

Albumin ikan gabus merupakan bahan farmasi bernilai tinggi, banyak dimanfaatkan untuk mengobati pasien pascaoperasi dan luka bakar. Penelitian ini bertujuan untuk menganalisis keragaman dan korelasi kandungan albumin terhadap karakter pertumbuhan pada tiga populasi ikan gabus (Chana striata) dari Sumatera (SM), Jawa (JW) dan Kalimantan (KL). Tahap awal dari penelitian ini adalah pemeliharaan larva-benih, karakterisasi dan analisis kandungan albumin ikan gabus dari tiga populasi. Kandungan albumin pada sampel daging (20 ekor ikan per populasi) dianalisis menggunakan reagen bromocresol green dan diukur dengan spektrofotometer pada 578 nm. Benih ikan gabus dari populasi SM, JW, dan KL dengan ukuran panjang total 28,9 ± 5,7 mm dan bobot badan 0,27 ± 0,09 g dari 12 famili, terdiri dari 4 famili untuk setiap populasi dipelihara secara acak dalam 12 buah kolam beton ukuran 25 m2 selama 75 hari. Kandungan albumin rata-rata ketiga populasi tidak berbeda nyata (P>0,05), yaitu 2,6 ± 0,4 g dL-1 (KL), 2,4 ± 0,3 g dL-1 (SM) dan 2,2 ± 0,4 g dL-1 (JV); dengan koefisien keragaman sebesar 12,60% (SM), 18,13% (JT) dan 17,0% (KL). Nilai korelasi antara panjang total, panjang standar, dan bobot badan dengan kandungan albumin tergolong rendah hingga sedang, yaitu secara berurutan sebesar -0,05; -0,03 dan -0,43 (SM), 0,42; 0,475 dan 0,34 (JW) dan -0,28; -0,35 dan -0,275 (KL). Hasil analisis tersebut menunjukkan bahwa keragaman kandungan albumin tidak berbeda antar populasi, sehingga pendekatan seleksi kurang efektif. Nilai korelasi antara karakter pertumbuhan terhadap kandungan albumin pada ikan gabus tergolong rendah. The snakehead fish (SHF) albumin is a highly valued pharmaceutical material widely used to treat postsurgery wounds and skin burns. This study’s purpose was to analyze the coefficient of variance and correlation of albumin trait to growth characters of three SHF populations: Sumatera (SM), Java (JV) and Kalimantan (KL). The first step of this study consisted of larval and seed rearing of three SHF populations followed up by characterization and analysis of their albumin content. The albumin contents of the SHF meat (20 fish for each population) were analyzed using bromocresol green reagent and measured using a spectrophotometer at 578 nm. The SHF seeds (28.9 ± 5.7 mm of total length and 0.27 ± 0.09 g of body weight) from 12 families consisted of four families for each population were reared in 12 concrete ponds measuring 25 m2 for 75 days. The averages of albumin content of the three populations were 2.6 ± 0.4 g dL-1 (KL) 2.4 ± 0.3 g dL-1 (SM) and 2.2 ± 0.4 g dL-1 (JV) and considered not significantly different (P> 0.05) with coefficients of variance of 12.60% (SM), 18.13% (JV) and 17.0% (KL). The correlation values of total length (TL), standard length (SL) and body weight (BW) with albumin content of the SHF were -0.05, -0.03, and -0.43 (SM); 0.42, 0.475, and 0.34 (JV); and -0.28, -0.35, dan -0.275 (KL) and classified as low to moderate. The results suggested that the variances of albumin content among the populations were not significantly different and the individual selection method was not effective.
