“…Based on the best of our knowledge, no previous studies on growth performance or stocking density were found in this species at fingerling stage. However, this observation have similar pattern with growth performance of other barb species in same genus (Barbonymus gonionotus), of Mollah et al (2011) and Faizul & Christianus (2013). They reported that the increasing of stocking density would affect negatively on fish growth, resulting in decreased growth rate.…”

Barb (Barbonymus balleroides) considerably has economic potential as aquaculture commodity. However, there was still lack of development on aquaculture for this species. This study was conducted to observe the effect of different stocking density on growth of barb. The fish (body weight: 14.89 ± 0.13 g) were stocked in nine floating nets (dimension: 2 m x 2 m x 1 m) inside the concrete ponds with three stocking density treatments (10, 15, and 20 fish/m3). Each treatment consisted of three replications. Fish were fed on commercial pellet (30% of crude protein) as much as 3% of the biomass per day with twice a day of feeding frequency. Data of growth performances (body weight, specific growth rate, average daily growth, biomass, food conversion ratio, and survival rate) were collected every 30 days during 90 days of rearing period. Water quality variables (temperature, pH, and dissolved oxygen) were observed during experiment. The results showed that the optimal stocking density for the growth of barb was 10 fish/m3. Best value of food conversion ratio was found 10 fish/m3 compared with 15 and 20 fish/m3 (P<0.05). Meanwhile, there were no significant differences on survival rate between treatments. These results also showed the potential of rearing barb on culture ponds with appropriate stocking density.

“…High values of DO in water are not unusual and mainly attributed to the direct contact of surface water with air and to the relatively higher photosynthetic activity compared to that in deeper depth of water. The DO concentration in Sembrong reservoir was regulated by the process of diffusion of oxygen from the atmosphere, photosynthetic activity, respiration and decomposition of aquatic organisms [4]. There was no significant difference in the concentration of DO among sampling stations because of the same water bodies and geographical area.…”

“…Generally, pH is almost the same in every layer of Sembrong reservoir due to the shallowness of the reservoir [7,8]. pH is a very important factor of water body for the fish culture as it controls the amount of soluble ions in the water [4]. An acidic pH of water reduces the growth rate, metabolic rate and other physiological activities of fishes [9], thus suggested that pH values varying from 6.5 to 9.0 as suitable for the normal growth of fishes.…”

A study of spatial and temporal variations on water quality and trophic status was conducted to determine the temporal (average reading by month) and spatial variations of water quality in Sembrong reservoir and to evaluate the trophic status of the reservoir. Water samples were collected once a month from November 2016 to June 2017 in seventeen (17) sampling stations at Sembrong Reservoir. Results obtained on the concentration of dissolved oxygen (DO), water temperature, pH and secchi depth had no significant differences compared to Total Phosphorus (TP) and chlorophyll-a. The water level has significantly decreased the value of the water temperature, pH and TP. The water quality of Sembrong reservoir is classified in Class II which is suitable for recreational uses and required conventional treatment while TSI indicates that sembrong reservoir was in lower boundary of classical eutrophic (TSI > 50).

“…In Bangladesh, carp species contributes about 1.2 million tonnes of fish food throughout the year that comprises almost 33% of country's total fish production (BBS, 2016). Barbonymus gonionotus (Bleeker, 1850) commonly known as silver barb belonging to the family Cyprinidae is the most popular and economically important exotic food fish in Bangladesh for its good taste, fast growth, highest protein content, bright silvery appearance and high yielding potential (Mollah et al, 2011;Zaman et al, 2014). In traditional culture practices of B. gonionotus, lack of effective formulated fish feeds are the main constraint to the sustainable as well as energetic fry management, which increases the fry mortality rate under poor culture conditions.…”

The dietary chitosan has been largely used in the supplemental diets of terrestrial animals to improve growth and development. However, there is little information on the roles of dietary chitosan in growth and development of aquatic animals like fishes. Thus, this study aimed at determining the effects of dietary chitosan on growth performances and survival of Barbonymus gonionotus fry. A total of 600 B. gonionotus fry (2.12±0.02 g) were considered for this study. This experiment consisted of four treatments (0, 1, 2 and 3 g Kg-1 formulated feeds) and each treatment had three replications with a stocking density of 50 fry/tank. The dietary chitosan was supplied as 8% of body weight of each fry twice daily for 60 days. Fish fry treated with the dietary chitosan exhibited significant (P < 0.05) improvement in growth (body weight gain, % body weight gain, specific growth rate, and feed conversion ratio) and survival of B. gonionotus in comparison with untreated control. The water quality parameters, such as temperature, pH and dissolved oxygen showed no significant variations, and maintained suitable range throughout the study period for fish growth. Among the treatments, application of 1 g chitosan kg-1 feed showed the highest positive effects on growth and survival of B. gonionotus fry, indicating their potentials for practical application in promoting sustainable aquaculture.
