Abstract/ Executive Summary:

The present study was performed for evaluating the growth and production performance of Thai and Vietnamese strain of climbing perch (Anabas testudineus) for the period of four months during April to July, 2014. There were two treatments each with three replications. Three ponds under treatment-1 (T-1) were stocked with fry of Vietnamese strain of climbing perch, while other three ponds which designated as treatment-2 (T-2) were stocked with Thai strain of climbing perch. Fish were fed with commercial pelleted feed (30% crude protein). The water quality parameters of pond water were monitored weekly and were within acceptable range for fish culture. The mean harvesting weight of treatment-1 was significantly higher than treatment-2. After four months of rearing, gross fish production of 15,352 and 9,456 Kg/ha were obtained from Vietnamese and Thai strain of climbing perch, respectively. The results demonstrated that the higher mean growth and production were observed in Vietnamese strain than Thai strain of climbing perch.

Program Area: Animal Health and Management

Commodity: Koi/Climbing

Objectives:

To evaluate the production potentials of Thai koi and Vietnamese Koi at on farm management.

Methodology:

The production potentials of Thai Koi and Vietnamese Koi were evaluated in six farmer’s ponds of 800 m² with depth of 1.2 to 1.5 m in Kheruajani under Muktagacha upazilla, Mymensingh district, Bangladesh and lies between 24.7583 °N and 90.2667 °E. Culture period of those fishes were four months during April to July, 2014. Pond preparation: The selected ponds were drained and unwanted fishes also removed. The dikes of all ponds were repaired and pond bottom treated with lime at the rate of 250 kg/ha. After that, ponds were filled up with underground water from deep tube well up to the depth of 1 meter. Design of experiment: The treated ponds were divided into two treatment groups and each having three replicates. The ponds under treatment-1 (T-1) and treatment-2 (T-2) were stocked with fry of Thai Koi and Vietnamese Koi (Anabas testudineus), respectively. The stocking density of both the treatments were same which was 1, 25,000/ha. Before stocking, the initial mean weights of the fry were measured using sensitive balance (Sciencetec Model JSA-210). Fish stocking and management: In both the treatments, 30% protein containing pelleted feed (Mega Feed Commercial feed) were applied at the rate of 15- 5% of estimated fish biomass twice daily at 10.00 hr in the morning and at 15.00 hr in the afternoon after stocking. The fingerlings were fed at the rate of 15% of their body weight for the first two weeks and it was reduced to 5% on the subsequent weeks. All the ponds were limed at the rate of 125 kg/ha during the culture trial at fortnightly interval. Fish sampling: Random samples of 50 individuals from each pond were caught by seine net at 10 days interval. The weight of fish was measured with a help of a portable sensitive balance (TANITA, Japan) to assess the health and growth of fish as well as to adjust the feeding rate. Water quality parameters: Water quality parameters like water temperature (°C), transparency (cm), pH, DO (mg/l), alkalinity (mg/l) and ammonia nitrogen (mg/l) were measured weekly interval throughout the study period from 0930 to 1000 hrs. Water temperature was recorded using a Celsius thermometer and transparency was measured by using a Seechi disc of 20 cm diameter. Dissolve oxygen and pH were measured directly using a digital portable oxygen meter (OAKTON) and portable pH meter (HANNA 8424), respectively. Alkalinity was determined following the titrimetric method according to the standard procedure and methods. Ammonia-nitrogen was measured using a high precision HACH Kit (DR 2800). Water Refilling: Shallow tube-well was used for adding underground water in the pond (1000 L. day^-1). This method mitigated pollution from excretory product of individuals and maintained water quality suitable for the experimental fish. Harvesting of fish: After four months of rearing fishes were harvested from all the experimental ponds. Primarily the harvesting of fishes was performed by repeated netting using a seine net and final harvesting was done by dewatering the ponds by submerged low lift pump. During harvesting all fish were counted and weighed from each pond. After harvesting, Specific Growth Rate (SGR), Food Conversion Ratio (FCR), Survival (%) and Production of fishes were calculated and compared between the treatments. Statistical analysis: The data were analyzed through one way analysis of variance (ANOVA) using the statistical package, STATGRAPHICS version 7. A simple cost benefit analysis was done to estimate the net benefits from the treatments.

Achievement/Findings:

The productivity of Vietnamese strain of A. testudineus was much higher than Thai strain of A. testudineus. The Vietnamese strain might be genetically superior to the Thai strain of A. testudineus. These indicated that Vietnamese strain of A. testudineus is an excellent candidate for aquaculture perhaps more than other culture species in Bangladesh.
