“…This could happen because of high number of phytoplankton present in catfish culture ponds and foods staying uneaten (Rahman et al, 2020). Ferdoushi and Haque (2006) recorded an increase in pH in pangas ponds as 9.10 which is higher than the current finding. Nitrate concentration was found null in all cases of mixed culture ponds possibly due to not using urea fertilizer while in catfish ponds it was within a range between 0-5 mg/L.…”

“…Nitrate concentration was found null in all cases of mixed culture ponds possibly due to not using urea fertilizer while in catfish ponds it was within a range between 0-5 mg/L. Haque & Ferdoushi (2006) during their investigation found that nitrate concentration was higher in pangasiid catfish ponds rather than culturing combination with silver carp. Ammonia concentration was found within a range between 0-0.25 mg/l in mixed culture ponds and within a range between from 0.25-1 mg/L in catfish ponds (Abedin et al, 2017).…”

An experiment was aimed to discover the overall scenario of physico-chemical parameters along with the qualitative and quantitative analysis of plankton in two different fish culture systems as carp mixed culture and catfish (Pangus) monoculture from September 2021 to February 2022 using conventional techniques. The mean values of transparency and dissolved oxygen (DO) noted at the catfish culture pond were lower than those at the mixed carp culture pond while pH mean values were observed to be higher in the catfish culture pond than in the mixed carp culture pond. A total of 21 genera of phytoplankton were found in both ponds under the groups of euglenophyceae (4), cyanophyceae (4), bacillariophyceae (5) and chlorophyceae (8). Among zooplankton, 13 genera were identified including Rotifera (7), copepoda (2), cladocera (3) and crustacean larvae (1) were recorded in mixed culture ponds whereas in catfish culture ponds, 11 zooplankton genera were recorded including Rotifera (5), copepoda (2), cladocera (3) and crustacean larvae (1). Planktonic abundances were statistically significantly different between the different levels (phytoplankton abundance in CCP, phytoplankton abundance in MCP, zooplankton abundance in CCP, zooplankton abundance in MCP), χ2(3) = 220.46, p < 0.001. Mixed culture pond cyanophyceae, bacillariophyceae, and euglenophyceae are positively associated with water temperature and pH but negatively correlated with DO. Rotifera is negatively associated with catfish culture pond water temperature, whereas chlorophyceae and cyanophyceae are favorably. Catfish monoculture ponds had higher phytoplankton abundance, so phytoplankton grazing fish species could be included with pangus culture to maintain a better water quality.

“…The lower stocking density in Bangladeshi ponds produces more oxygen and lowers ammonia than the ponds in Vietnam. Furthermore, the lower stocking density in shallow ponds may facilitate the growth and abundance of phytoplankton and different types of algae resulting off-flavor and discoloration of fish fillets ( Ferdoushi and Haque, 2006 ). The dominating algae in Bangladeshi ponds is Chlorophyceae (47%) containing a higher levels of carotenoids ( Mukherjee et al., 2013 ).…”

Prospects and challenges of yellow flesh pangasius in international markets: secondary and primary evidence from Bangladesh

The projected increase in aquaculture production by 2030 will mostly occur in countries of Asia and Africa, including Bangladesh. The pangasius ( Pangasianodon hypophthalmus ) produced in Bangladesh, the second-largest producer globally, is mainly consumed by low-income domestic consumers and is poorly demanded in international markets. One reason for this is the yellow flesh of fish; consumers generally in mainstream international markets prefer to fish with white flesh. Reviewing secondary evidence and analyzing primary data, this article assesses the underlying reasons for the discolored pangasius flesh in Bangladesh and synthesizes strategies for avoiding discoloration to induce exports. The findings indicate that farming practices with high stocking density, infrequent water exchange, high organic matter in pond water, and the growth of carotenoid-containing cyanobacteria contribute to the discoloration of pangasius flesh. Artificial and natural pigments in feed and poor post-harvest handling of fish are also contributing factors. Furthermore, a positive correlation between water exchange, price, and yield at the farm is found, which indicates that farm-gate price and yield per hectare can increase with more frequent water exchange. The findings of this study provide strong evidence that improved aquaculture practices can solve the problem of discolored pangasius flesh and establish an export-oriented pangasius industry in Bangladesh.

“…It is by and large thought to be a planktivorous fish (Anderson et al 2016). Planktivorous Silver carp and Pangasiid catfish together in a polyculture system can make better the pond water parameter by skimming the phytoplankton by the second species and enhance the growth rate of past species (Ferdousi and Haque 2006). Population density of fish is an imperative factor influencing the growth rate and development of wild and farmed fish species alongside food supply and its hereditary qualities, and natural conditions (Malik et al 2014).…”

The experiment was operated in 9 consecutive weeks in nine earthen nursery ponds having the same area (0.09 acre) and depth (0.8 m). Seven days old fries of Silver carp (Hypophthalmichthys molitrix) were stocked at 4000, 5000 and 6000 fries/decimal in three treatments with three replications as T-1, T-2 and T-3, respectively to observe the growth and survival. At stocking, hatchlings were the same batch-rearing with an average length and weight of 0.44 ± 0.05 cm and 0.14 ± 0.05 mg, respectively. Wet mustered oil cake and commercial nursery feed containing 30% crude protein were given by two weeks interval, initially according to the bodyweight; the feeding rate was 14% in the first two weeks, gradually reduced to 12, 10 and 8%, respectively in the following week intervals. Water quality parameters and plankton sufficiency were observed every 15 days interval and was found within the acceptable range. Growth performance (6.458 g), survival rate of fingerlings (85.76%) and total production (22151g/decimal) were found highest in T-1 followed by T-2 and T-3. The study concluded that expect better production of fry up to fingerlings, proper stocking density should be maintained in pond fish culture in Jashore region of Bangladesh.
