Abstract/ Executive Summary:

To assess the growth and culture potentials of Indian white prawn Penaeus indicus, locally known as Chaka Chingri, a preliminary trial was conducted for a period of 145 days in earthen ponds. The post larvae were collected from Sundarbans coast and stocked in 3 ponds of 0.056 ha each with the stocking density at 30, 40 and 54 m-2in T₁,T₂ and T₃ treatments respectively. Commercial pelleted feed with 36% protein was fed. Production and physico-chemical parameters were recorded and analyzed according to standard methods. After 145 days of rearing, obtained average final weight was 22.18±6.71g, 25.25±3.11g and 29.25±2.88g; with the estimated yield of 1197 kg/ha, 3030 kg/ha, and 3632 kg/ha, survival was 18%, 30% and 23% in T₁, T₂ and T₃ treatments respectively. Results and findings of the present study suggested that P. indicus might be potential mariculture candidate in the coastal areas of Bangladesh.

Keywords: Penaeus indicus, Culture, Stocking density

Location: Bagerhat sadar, Mongla, Rampal, Shoronkhola and Morelgonj upazila of Bagerhat district as well as Batiaghata upazila of Khulna district, Bangladesh

Start Date: 00-02-2019

End Date: 00-04-2019

Program Area: Risk Management in Agriculture

Commodity: Prawn, Water salinity

Objectives:

To observe the growth, survival and production potentials of P. indices under different stocking densities in earthen ponds.

Methodology:

Collection of baseline information: Baseline information regarding traditional culture practices of chaka chingri was collected through a pretested questionnaire survey in 2019. Sampling was done in Bagerhat sadar, Mongla, Rampal, Shoronkhola and Morelgonj upazila of Bagerhat district as well as Batiaghata upazila of Khulna district. A total of 60 sets of data were collected through direct personal interview and using Focus Group Discussion (FGD) tool with different stakeholders. Sampling frequencies were twice in every month from February to April 2019. Pond selection and preparation: The culture experiment was conducted in tide fed three earthen ponds of Shrimp Research Station under Bangladesh Fisheries Research Institute. The ponds had an area of 0.056 ha each with a water depth of 1m. The ponds were prepared bydrying, removing of unwanted sludge and repairing of embankments .Lime was applied at the rate of 250 kg/ha in the ponds and left for seven days. Ponds were filled with tidal water from the Daratana river during high tide and left for 3 days to settle down. Pond water was fertilized with compost cow dung@1,250kg/ha, urea @37.5kg/ha and TSP @25kg/ha. These ponds were left for10 days to promote primary food production. Collection and stocking of PL: The wild post larvae (PL) were collected from the Sibsha River of Khulna districts adjacent to the Sundarbans mangrove forest, acclimatized and stocked in the pond in March, 2019. Feed and feeding management: The shrimps were fed with commercial CP prawn feed with 36% protein level. Initially feed was provided at 13% of biomass of post larvae and subsequently decreased to 2.5%. Feed was adjusted periodically in accordance with the growth performance, total biomass and assuming 100% survival of P. indicus. Feeding schedule was twice in a day at dawn and dusk for the first month, while it was once in day for the rest of culture period. Feed was provided on 5 feeding trays having an area of 1 m2 each. The feed trays were hanged to the bamboo poles and allowed to submerge in the water column. Pond water was fertilized with urea (37 kg/ha) and TSP (25kg/ha) at 15 days interval to enhance natural foods, whereas limed with calcium carbonate at the rate of 65/ha at 15 days intervals to maintain congenial water quality. Monitoring of physico-chemical water parameters: The physico-chemical parameters of pond water were monitored at 9:00to 10:00AMin every 7 days. Water quality parameters like water temperature (oC), DO (mg/l), CO2 (mg/l), total alkalinity (mg/l), pH, iron (mg/l),ammonia (mg/l) was monitored using HACH Kit Box. Transparency (cm) was measured by using secchi disc and water depth (cm) was measured manually by using meter scale. Monitoring of growth and estimation of production: Health condition and growth of shrimp was monitored fortnightly during the full and new period. At least 5% of shrimp was collected by a cast net in early morning. Length was measured by using a centimeter scale and the weight by a portable weighing balance. After 145 days of rearing, all shrimp were harvested with seine net and the following parameters were calculated: Average weight gain (g) = Mean final weight (b) – mean initial weight (a); Specific growth rate SGR (%body wt. gain/day) = [(Logn Final wt.- Logn Initial wt.)/ Time interval] × 100); Survival (%) = (Number of fish harvested/Number of fish stocked) × 100; Production/Yield (kg/ha) = [{Number harvested × average final wt. (g)/1000] × pond area (ha); and Food conversion ratio (FCR) = Supplied feed (kg)/harvested total biomass (kg). Data analysis: Comparison of treatment mean was carried out using one-way analysis of variance (ANOVA), followed by Duncan's Multiple Range Test. Significance at the 5% level (p<.05) using the SPSS (Statistical Package for Social Science) version-20.

Achievement/Findings:

Information regarding traditional culture practices and production of Indian White Shrimp are presented. Farmers stock chaka chingri during February to March with a very low density of 150/decimal. They follow mixed culture system with other shrimp and finfishes. Sometimes they follow integrated culture with paddy and dyke cropping with seasonal vegetables. Though they never keep records on production of specific species but harvested variety of native shrimp species including Indian White Prawn those entered through tidal water. Growth, survival, stoking and harvesting details of P. indicus juveniles at the end of 145 days are detailed in this section. Recorded water quality parameters are also reported. The initial weight of P. indicus was 0.0123 g and stocking densities were 30/m2 , 40/m2 , 54/m2 in T₁, T₂, and T₃ treatments respectively. After culturing 145 days the average body weights were 22.18±6.71g, 25.25±3.11g and 29.25±2.88g, with a specific growth rate of 5.31%, 5.40%, and 5.50% in T₁, T₂, and T₃ respectively. The percentage of survival was 18%, 30%, and 23% in T₁, T₂, and T₃ respectively. The mean FCR value was1.05, 0.99, and 1.04 which indicates feed consumption was comparatively lower in T₂ treatments (p<.05). According to APHA (2005) and Boyd and Fast (1992) recorded all physico-chemical variables like dissolved oxygen, pH, alkalinity, ammonia, nitrite, iron and transparency; were found within the acceptable ranges for crustacean aquaculture except the lower salinity levels inT₁, T₂, and T₃ treatments respectively during the entire culture period.
