An experiment of 36 days duration was conducted to study growth performance of goldfish Carassius auratus and basil Ocimum basilicum reared in a media bed aquaponic system. Goldfish fry (3.32 ± 0.45 g and 4.20 ± 0.39 cm) were stocked in rectangular 75 l capacity (water volume of 50 l) plastic tanks at three different stocking densities viz., 500 m-3 (T1), 600 m-3 (T2) and 700 m-3 (T3), respectively and basil plants were planted at a density of 20 m-2, i.e., 10 plants 0.44 m-2 in the rectangular plastic tanks filled with crushed stone media. The goldfish fry were fed with artificial feed (33% protein) at 5% of body weight in equal proportions, two times a day. Control (C) group was set with only basil plants. Growth parameters of goldfish such as length gain (%), weight gain (%) and specific growth rate (% d-1) were significantly higher in T3 (p<0.05) as compared to T1 and T2. However, feed conversion ratio (FCR) and protein efficiency ratio (PER) did not differ between treatments. Similarly, basil plant growth in terms of height gain (%) and leaves yield (nos. plant-1) were found to be highest in T3 which was significantly different from T1, T2 and control (C). Throughout the experimental period, values of water parameters in all the treatments were found to be in favourable ranges. From the results of the present study, it could be concluded that for maintaining good water quality with highest production in media bed aquaponics, the optimum stocking density is 700 m-3 for goldfish fry and 10 plants per 0.44 m2 for basil plants.

The study was conducted to compare the effect of three different fry rearing systems such as: hapa, cistern and pond on the growth and survival of goldfish (Carassius auratus ) fry. A total of 645 fry (mean initial weight: 0.0071 mg) were randomly distributed in the three treatments (systems) each having three replications. The stocking density was same in all the treatments with respect to the water volume of the systems which was 10 fry/hapa, 125 fry/cistern and 80 fry/pond. The trial lasted for 40 days. The water quality parameters were favorable in all the treatments during the period of the study. The growth and survival of goldfish fry varied among the systems. Highest average weight gain and specific growth rate (SGR) were observed in pond followed by hapa and cistern. On the other hand, survival rate was highest in cistern followed by hapa and pond. It can be concluded from the study that the pond was the best system in terms of growth rate and cistern was the best system for survival of gold fish fry.Res. Agric., Livest.

A research was done at Aquaculture department laboratory of Institute of Agriculture and Animal Science Paklihawa Campus, Rupandehi from 28 February 2017 to 28 April 2017 using two ornamental fishes; Goldfish (Carassius auratus) and Red cap oranda (Carassius auratus auratus) . Twelve rectangular glass aquarium of size of 12” × 24” × 12” were used for the purpose to assess the growth performance and feeding efficiency. Four treatments selected for this purpose were local feed containing rice bran and mustard oil cake (MOC) in T1 (Control), Local Feed with 5% Cassava leaves powder in T2, Local Feed with 5% Sweet Potato leaves powder in T3 and Local Feed with 5% Colocasia leaves powder 5% T4 during the experimental period. The initial weight of red cap was significantly lower in T3 as compared to T1 but was at par with T2 and T4. Furthermore, the final weight was not significantly different among the treatments. In case of goldfish, the initial weight at T4 was significantly lower than T2 but was at par among other treatments. The final weight was significantly higher in T2 as compared to T4 and T3 was at par with T1. Feed conversion ratio (FCR) was observed higher in case of T2 (6.981±3.14) and lower in case of T3 (3.325±0.48). However, no significant difference was noticed among the treatments. Specific growth rate (SGR) was observed higher in T3 (0.0370±0.088) as compared to other treatments. However, in this case also, no significant difference was observed. Survivability percentage for red cap fish was observed higher in T3 (100±0.00) and least inT2 (50.000±40.82), whereas, survivability was 100% for goldfish in all the treatments. The average survivability was highest (100%) in T3 for both kinds of fishes and minimum in T2 (75±20.41). Also, the mean pH observed at T1, T2, T3 and T4 was 9.165, 9.222, 9.196 and 9.172 respectively. Similarly, daily mean dissolved oxygen recorded at T1, T2, T3 and T4 was 6.23 mg/l, 6.16 mg/l, 6.267mg/l and 6.147 mg/l respectively. Moreover, the mean average temperature recorded in these four treatments; T1, T2, T3 and T4 were 23.342°>C, 23.272°C, 23.342°C and 23.339°C respectively.

This study was conducted to investigate and compare the growth performance of four Tilapia strains in hapa nursing with the aim to find out the best strain of tilapia. The research was conducted by four treatments with five replicates each. The tilapia fry were collected from, BFRI source from BFRI HQ, Mymensingh stocked in Treatment-1; unknown source from Hi-Tech Tilapia Hatchery Dagoanbhuiya, Feni in Treatment-2, Philipine strain from Green Field Tilapia Hatchery, Laxmipur in Treatment-3 and fry from Breeding Cohort, Sonar Bangla Hatchery, Bamna, Barguna in Treatment-4. The Individual stocking weight (g) of fry was average 0.01g. The fries were stocked in 12 hapa at same stocking density of 1200 fish/m2. Each of the hapa was 2m × 1m × 1m size and fixed in an earthen ponds. Supplementary feed with 31.29% of protein level consisting of rice bran (25%), mustard oil cake (15%), wheat flour (30%) and fish meal (30%) was given at the rate of 40% of their body weight per day manually, four times a day at the beginning of the experimental period and reduced to 25% of their body weight and continued up to harvesting period. The results showed that fry of Treatment-4 strain was the best strain and had significantly (p < 0.05) higher final mean body weight (FMBW), mean body weight gain (MBWG), specific growth rate (SGR) (9.75%), gross yield (GY) (2.13) and Net yield (NY) (2.12) than the Treatment-1 , Treatment-2 strains and Treatemnt-3 strain. Treatment-4 strain had the fastest growth rate, whereas the lowest performing strain was that from Treatment-2. We also analyzed survival rate of the fish from stocking to harvest, survival rate was highest in Treatment-4 strain (80%) where lowest is Treatment-3. Treatment-4 stain also showed the best feed conversion ratio (FCR) 1.62 than others. Considering the overall performance it can be concluded that tilapia strain collected from Breeding Cohort source is best among the four strains. However, further research may still be needed to compare more strains from different water body to evaluate the genetic potential for Tilapia.International Journal of Natural Sciences (2015), 5(2) 98-106

Goldfish Carassius Auratus

Red cell numbers and haematocrit values were notable principally for their constancy during a 10-day experimental period following the exposure of goldfish acclimated to 20 C to an abrupt increase of 10 C in environmental temperature. Mean erythrocytic volume underwent a transient decrease while total blood iron (and presumably haemoglobin) and mean erythrocytic iron content fell slightly during the latter portion of the period of observation. Goldfish maintained at 5 C were typically characterized by two haemoglobin polymorphs, a third fraction being commonly found in animals acclimated at 12, 20, and 30 C. The observations are discussed in relation to the respiratory acclimation of this species to increases in environmental temperature.

Growth performance and survival of Tor putitora fry under different stocking densities were evaluated fry rearing system. The experimental period was 10 weeks from 31 December to 10 March 2019. The experiment was carried out in nine earthen ponds of 0.04 ha each under three treatments with three replications.  Thirty days old fry were stocked at the rate of 1.0X105/ha was designated as treatment- 1 (T1), 1.5X105/ha` as treatment- 2 (T2) and 2.0X105/ha as treatment- 3 (T3), respectively. Fry were fed with commercially available nursery feed containing 32% crude protein. It was observed that, lower stocking density showed highest daily weight gain in T1 (growth 0.066 ± 0.006 g/day) compared with higher stocking density in T2 (growth 0.044 ± 0.004 g/day) and T3 (growth 0.024 ± 0.003 g/day), respectively. It is also noticed that, the lower stocking showed the highest survival rate (79.66 ± 4.34 %) than the other two treatments (66.97±3.67 and 54.67± 3.12 %). The values of different water quality parameters were within the optimum ranges for the rearing of carp fry. Water quality parameters did not show significant variations in the experimental ponds under different stocking densities. Among these three stocking densities lower stocking density (T1) showed the best result compare with the other two higher stocking densities.

Silver Barb

An experiment was carried out to study the density dependent growth of silver barb   (Barbonymus gonionotus) for a period of 2 months during14 March to 18 May, 2013 in ponds with individual water area of 2.0 decimal. The experiment was conducted with three treatments, replicated three times, where stocking densities were 50, 100 and 150 fish/decimal in T1, T2 and T3, respectively. Feeds were supplied twice daily throughout the study period. Sampling was done at weekly interval throughout the experimental period. Water quality parameters were monitored weekly. Temperature ranged from 26.40 to 30.13°C, transparency from 32.36 to 46.23 cm, dissolved oxygen from 4.80 to 5.83 mg/l and pH from 6.68 to 8.11. During the study period, growth parameters were analyzed. The mean weight gains were 52.48, 49.98 and 47.87 g, the percent weight gains were 2560.16, 2438.37 and 2335.12, the average daily weight gains were 0.82, 0.78 and 0.74 g, the specific growth rates were 5.12, 5.05 and 4.98%, the survival rates were 89.6, 86.67 and 82.11% in T1, T2, and T3, respectively. There were significant differences among T1, T2 and T3 for all the growth parameters. The total productions of silver barb were 603.85, 1114.00 and 1518.06 kg/ha/2 months in T1, T2 and T3, respectively. The present study indicates that the growth of silver barb was density dependent when grown in monoculture systems and the best stocking density for production was 150 fish/decimal. The Agriculturists 2016; 14(2) 61-66
