“…At higher stocking densities, presence of abundant feed substance could produce a competitive interaction among the larvae causing a stressful situation (Houde, 1975). Similar results were observed by Rahman et al (2017b) and Haq et al (2017). In the present experiment the average survival rate of Vietnamese koi and Magur were found at the end of the experiment which were 95.14% and 72% in T 1 ; 93.25% and 64% in T 2 ; 90.80% and 68.00% in T 3 respectively.…”

A culture experiment was conducted to see the growth and production performance of Vietnamese koi (Anabas testudineus) with Magur (Clarias batrachus) at different stocking densities in a farmer’s ponds under semi-intensive rearing system for a period of 120 days. The experiment was conducted in three ponds at Rahmatpur of Muktagachha Upazila of Mymensingh district from 5 August to 5 December, 2013. The size of ponds were 24 (T1), 24 (T2) and 24 (T3) decimal with an average depth of 4 feet. Three different stocking densities were tested, namely treatments T1 (400 fish /decimal, 350 Vietnamese koi and 50 magur); T2 (450 fish /decimal, 400 Vietnamese koi and 50 Magur) and T3 (550 fish /decimal, 500 Vietnamese koi and 50 Magur). Ruposhi Bangla feed was used in all treatments two times daily from the beginning of the fry stocking. The initial weight of Vietnamese koi and Magur were 5±0.00 g and 2±0.00 g respectively. The initial length of Vietnamese koi and Magur were 2.54 and 3.50 cm respectively. The average highest final weight gain of Vietnamese koi was (138.71±0.03 g) observed in T1 and followed by T2 (135.65±0.12 g) and T3 (129.29±0.49 g). Similarly, the average highest final weight gain of Magur (76.00±0.58 g) was observed in T1 and followed by T2 (68.36±0.43 g) and T3 (62.61±0.58 g) respectively. The average highest final length gain of Vietnamese koi (17.38±0.05 cm) was observed in T1 and followed by T2 (17.00±0.04 cm) and T3 (16.33±0.03 cm). Similarly, the average highest final length gain of Magur (21.30±0.09 cm) was observed in T1 and followed by T2 (17.00±0.05 cm) and T3 (15.87±0.02 cm) respectively. The survival rate of the stocking Vietnamese koi and Magur were recorded 95.14 and 72.00 % in T1; 93.25 and 64.00% in T2; 90.80 and 68.00 % in T3 respectively. Fish production in T1, T2 and T3 were 48.93; 52.79 and 60.83 kg/decimal/120 days, respectively. The total production of T3 was increased with the increasing of stocking density compare to T2 and T1. The benefit-cost ratio (BCR) was higher in T3 where BCR was 1.67 and on the other two treatments BCR was 1.53 in T2 and 1.52 in T1 although the highest production was obtained in T3 but individually growth performance of Vietnamese koi and Magur were higher in T1. Based on the result of the present experiment, farmers could be suggested to rear Vietnamese koi with Magur at the stocking density of 550 fish/decimal (500 Vietnamese koi and 50 Magur) which was the highest density tried to get more production and financial benefit. Further experiment need to be conducted by taking higher density than the 550 fish/decimal for the optimization of stocking density to get more production and benefit. Asian Australas. J. Biosci.

“…Kujawa (2004), Kwiatkowski et al (2008), recorded crucian carp body weight ranged 1.3 to 3.0 mg. Rcma and Gouveia (2005) recorded 0.9 mg of wet body weight of fish. Similar study was conducted by Samad et al (2016); Islam et al (2017); Rahman et al (2017); Rahman et al (2016); Anka et al (2016); Ali et al (2016); Zaman et al (2017) and Haq et al (2017); they got relevant results. It was observed that the highest weight gain of gold fish fry was obtained from anent T 1 which might be due to lower stocking density and lower competition for lowest weight gain was obtained from T 3 which might be due to comparatively her stocking density so the feeding competition may occur among the species.…”

“…The results indicated that the percent weight gained in different stocking densities which coincides with the findings of Begum (2009) found percent weight gain ranged from 7986 to 9406%. Study of Ali et al (2016); Zaman et al (2017) and Haq et al (2017) was also relevant with present study.The percent weight gain of present study was lower than findings; this might be due to the temperature difference between regions and natural productivity of the ponds. The other reason might be due to the difference of culture season.…”

Abstract:The present study was conducted to investigate effects of stocking density on growth performances of gold fish (Carassius auratus) in hapas. Experiment was conducted for a month with three treatments where three stocking densities were T 1 (10 fry/hapa), T 2 (15 fry/hapa) andT 3 (20 fry/hapa) each having three replications which were selected randomly. In the present experiment hapa (3ft × 2ft × 2ft) with 1 mm mesh net was used. Gold fish fry having a mean body weight of 0.007 g were used in all treatments. Fishes were fed at the rate of 10% of their body weight containing 34.11% protein. Water quality parameters were monitored at 10 days interval and the ranges were -temperature 24.75 to 27.75 o C, dissolved oxygen 3.68 to 4.09 mg/L, p H 7.3 to 8.16, ammonia 0.3 to 1 mg/L, nitrite 0.01 to 0.03 mg/L, phosphate 0.6 to 1 mg/L and alkalinity 119 to 187 mg/L. At the growth performances were evaluated by comparing mean final body weight, specific growth rate and food conversion ratio. The present study showed that the gold fish fry in T 1 resulted the best mean final weight gain (1.188 g) followed by T 2 (0.834 g) and T 3 (0.686 g). The SGR ranged between 6.64 and 7.43% per day and FCR ranged between 3.56 and 4.12 with T 1 showing the lowest FCR. The survival rate (%) ranged between 76.67% to 85.67%. From the present experiment it was found that individual fish growth rate was decreased with the increase of stocking density.

“…Malla and Banik (2015)reported that SGR of Ompak bimaculatus was 4.79±0.58 to 3.46±0.31 that is similar with the present study. Similar phenomena were also observed in other fish species, for instance, tilapia (Haq et al, 2017). The highest survivability was recorded in treatment T 2 (96.77 ±0.01) and the lowest survivability was in treatment T 1 (90.43 ±0.01).…”

Growth and production of near threatened Ompok pabda (Hamilton) were examined at different feeding frequencies in the present study. The experiment was conducted for four months in three earthen ponds from 1st April to 31st July 2018 at Tanore Upazila in Rajshahi district, Bangladesh. The experiment was performed using pabda, (Ompok pabda) fingerling (average) to study the effect of feeding frequency on growth performance. The study carried out considering three treatments, namely T1, T2, and T3; while the feeding frequency was two times per day in treatment T1, three times per day in treatment T2, and four times per day in treatment T3. Fish were fed considering three-stage of life span; these were fingerling stage, early growing stage, and growing stage. In the fry stage, the fishes were fed 20% feed, in the fingerlings stage the fish were fed 10% feed and in the growing stage, the fish were fed 8% feed of the body weight. The mean water temperature ranged between 27.13±2.10 and 27.29±2.16 °C among treatments, while water transparency ranged between 31.91±1.58 and 29.96±1.84 cm. pH ranged between 7.62±0.14 and 7.70±0.19; while the mean dissolved oxygen was ranged between 5.35±0.11 and 5.56±0.14 among treatments. The final weight gain was found to be highest (56.36±0.01) in the treatment T2 and lowest (38.23±0.01) in the treatment T3. The SGR value was higher (3.94±0.01) in the treatments T2 followed by treatments T1 and T3. Net weight gain was significantly (p<0.05) higher in feeding frequency three (56.36±0.1), followed by feeding frequency four (38.23±0.1) and feeding frequency two (40.67±0.73). The FCR value ranged between 1.90 and 2.87 among treatments. The growth performance and specific growth rate were significantly (p<0.05) higher in feeding frequency three. The highest (4049.1±0.1 kg/ha/120 days) production was observed in T2. Best cost benefit ratio was gained in treatment T2. Asian Australas. J. Biosci. Biotechnol. 2021, 6 (2), 89-102
