Abstract Chinese mitten crab, Eriocheir sinensis, native to the coastal streams and rivers of China, is one of the most famous and widely cultured aquatic animals in China, well-known for its special appearance and delicious taste. Pond culture of mitten crab has a long history in China and culture systems vary from extensive, semi-intensive to intensive operations. This case study describes intensive pond culture techniques of the crab in relation to broodstock management, breeding, larval nursing, grow-out and harvest.

The Mean

An experiment was conducted to compare production and economic performance of Thai Climbing Perch (Anabas testudineus) and Tilapia (Oreochromis niloticus) under three management systems. The nursed juveniles of Thai Climbing Perch (6.22 ± 0.15g) and Tilapia (22.52 ± 0.73g) were stocked at 50 Thai Climbing Perch per 1m3 cage and 50 Tilapia per 80m2 open pond (Caged Perch); 50 Tilapia per 1m3 cage and 50 Thai Climbing Perch per 80 m2 open pond (Caged Tilapia); and both 50 Thai Climbing Perch and 50 Tilapia per 80m2 pond (Mixed culture) as three treatments with three replicates for each. Pelleted feed (35% crude protein) was given twice daily (8.0 h and 16.0 h) at a rate of 10% body weight of Thai Climbing Perch for first month and 5% body weight of Thai Climbing Perch for rest of the culture period (90 days) to cages for the integrated cage-pond culture and to open ponds for the mixed culture. Among the measured water quality parameters transparency (cm), alkalinity (mg l-1), nitrite-nitrogen (mg l-1), and chlorophyll-a (μg l-1) were significantly different among the treatments. A total of 43 genera of phytoplankton and 16 genera of zooplankton were identified from the pond water. The mean abundance of total macro-benthic organisms was not significantly different (P>0.05). The mean survival rate of Thai Climbing Perch was high, ranging from 86.67% to 98.67%. Gross yield of Thai Climbing Perch was the highest in the Caged Perch. Survival of Tilapia was also high, ranging from 94.00% to 96.67%. The combined FCRs were 0.75, 0.77 and 0.85 in the Caged Perch, Mixed culture and Caged Tilapia systems, respectively. Economic analysis revealed that a significantly higher (P<0.05) cost-benefit ratio was obtained in the Caged Perch treatment. Therefore, it is concluded that the integrated cage-pond culture system with the high-valued Thai Climbing Perch in cages and low-valued Tilapia in open ponds may be a better option for rural pond aquaculture considering the production and economic benefit.

An experiment was conducted for a period of 97 days at the Fisheries Field Laboratory Complex, Bangladesh Agricultural University, Mymensingh to determine the potential of the cage-cum-pond culture of walking catfish, as well as to assess the economic and environmental benefits of this system. The experiment had two treatments in triplicate. One treatment comprised walking catfish in cage and tilapia in open pond, and the other treatment comprised both walking catfish and tilapia stocked together in open ponds. Ponds of both treatments were stocked with walking catfish and tilapia at a stocking density of 10,000 and 20,000 ha-1, respectively. Fishes in both treatments were fed with commercial pelleted feed (26% crude protein) twice daily at the rate of 10% body weight of walking catfish. All ponds were fertilized with urea and TSP at a rate of 50 kgha-1 bi-weekly. Survival of catfish was very low in both treatments ranging from 8.33 to 21.33%. Specific growth rate of catfish was significantly higher (P<0.021) in treatment-2 than in treatment-1 with a value of 2.42 and 1.69 g fish-1d-1, respectively. The net yield for catfish of treatment-1 and 2 were 49.67 and 43.45 kgha-1, respectively and there was no significant difference between the treatments. The survival rate of tilapia was 65.17 and 71.17% with daily weight gain of 2.31 and 2.22g fish-1 in treatment-1 and 2, respectively. Net yield were 817.00 and 790.63 kg ha-1, respectively and there were no significant difference in net yield of tilapia between treatments. Net profit obtained from integrated-cage-cum pond culture (Tk. 24,518 ha-197d-1) was higher than that of open pond (Tk 22,685 ha-197d-1).Res. Agric. Livest. Fish.4(3): 221-227, December 2017

Game Changer

Single-celled photosynthetic microscopic algae (microalgae) have numerous significances for human wellbeing. From medicine to fuel industry these tiny organisms have tremendous potentials and in future they would be game changer to mitigate global warming and environmental pollutions. The current production cost is a matter of consideration during its applications. Scientists all over the world are trying to reduce the production costs as well as to develop new or improve the existing culturing methodologies and techniques. Open pond and closed pond (PBRs) culturing system are two most prominent ways to culture microalgae. Open pond culturing techniques for microalgae have several advantages over closed pond system such as low operational costs and easy to make. However, the main drawback of this system is contamination by other microorganisms, which is possible to control in closed pond system. Among the many types of PBRs systems, the advanced tubular PBRs presently considered as more useful than open pond culture system. To meet the minimum production costs, more research is needed on both the culturing systems.
