Abstract/ Executive Summary:

A study was conducted to assess the growth performance and survival rate of a commercially important finfish Eleutheronema tetradactylum in 100 m^-2 of sandy clay brackish water earthen ponds. Wild 36.14 g of E. tetradactylum juveniles were stocked at 0.5 individuals m^-2 and cultured for 45 days by feeding trash Muraenesox sp. (pike eel) at 12 h intervals. Average body weight of E. tetradactylum was found 75±5.6 g for treatment ponds and 65±3.57 g for control ponds at the end of experiment. Feed Conversion Ratio (FCR) was 2.3 with the survival rate of 70-80% at the end of the culture in the experimental culture ponds. The results of the present study suggest that, the production of four finger thread fin could still be increased up to the marketable size if it is cultured for 5-6 months period by feeding trash fish.

Keywords: Aquaculture, Eleutheronema tetradactylum, Coastal belt, Four finger thread finfish, Earthen pond

Location: PC Park Hatchery (a commercial private firm) at Cox’s Bazar, Bangladesh

Start Date: 00-11-2007

End Date: 00-01-2008

Program Area: Variety and Species

Commodity: Fish

Objectives:

To investigate the growth and survival of E. tetradactylum in the earthen pond
To study feasibility of introducing it for the development of aquaculture in the abandoned coastal shrimp culture ponds

Methodology:

The present experiment was conducted in the earthen coastal ponds of PC Park Hatchery (a commercial private firm) at Cox’s Bazar, Bangladesh from November 2007 to January 2008. Six 1.5 m in depth earthen ponds (10x10 m) prepared by bamboo fence were selected for this experiment. Three ponds were used as Treatment (T) while others were used as Control (C). All ponds were prepared by cleaning trashes and exchanges of water for 2 to 3 times. The fingerlings of E. tetradactylum were collected from the traditional shrimp culture ponds where it grows as by products. The fingerlings of E. tetradactylum with the size of 36.14 g were stocked at 0.5 individuals m^-2 in each culture pond for 45 days experimental trails. Aside from the live food available in the culture ponds, the chopped trash pike eel Muraenesox sp. was applied every day at the rate of 5% of the total body weight of E. tetradactylum (Biomass) in the pond. Half of the total feed was applied in the morning and the other half in the afternoon through spreading by hand. The feeding rate was monitor through checking in the feeding tray after two hours post feeding. In control ponds, no feed was given. Ten live fish were collected from each pond at every fifteen days intervals thus a total of ten samples were used to determine the body weight, specific growth rate and mean daily growth rate and feed conversion ratio. The weight of fish was determined to the nearest gram. Water quality parameters were measured in situ at fifteen days intervals throughout the culture period. Water salinity, pH and temperature were estimated by refractometer (o~100, OSK, Japan), pH meter (Hanna, Italy) and mercury thermometer respectively. A Secchi disk to nearest cm determined transparency of water. Surface (<0.5 m depth) water samples were collected from each culture pond. The collected samples were preserved by HCl for further analysis and brought back to the IMSF laboratory in an icebox. Dissolved Oxygen (DO) and Total Suspended Solid (TSS) was determined. Simple t-test was used to compare the means of two sets of observations both at treatment and control ponds using SPSS version 10. Correlation regression analysis was used to find out the best physico- chemical parameters for fish growth during the culture period in ponds.

Achievement/Findings:

This study concludes that, the production of the four finger thread fin could still be increased up to the marketable size had it been done for 5-6 months culture period. Once the higher yielding culture of this technology (mono or poly) of E. tetradactylum becomes established, abandoned shrimp ponds of the coastal area could be reverted productive for economic return
