Diversification of Culture Practice for Optimizing Production of the Shrimp (penaeus Monodon) Culture System in the Coastal Ghers

Abstract/ Executive Summary:

The production performance of shrimp in both short and long culture ponds are summarized in Table 2. In the 1^st crop of short cycle (60 days) culture, average growth of shrimp was 17.39g, 16.51g and 15.87g and production of shrimp was 406.92 kg/ha, 747.80 kg/ha and 1007.92 kg/ha at 3, 5 and 7 Nos/ha density, respectively. In the 2^nd crop of short cycle (60 days) culture, average growth of shrimp was 20.42g, 16.03g and 14.79g at 3, 5 and 7 Nos/m² density, respectively. In the long cycle (120 days) culture, average growth of shrimp was 39.36g, 32.51g and 30.51g and average production of shrimp was 913.57 kg/ha, 1429.38 kg/ha and 1857.31kg/ha at 3, 5 and 7 Nos/ha density, respectively. Total production of both 1^st and 2^nd crop of short cycle culture was higher than that of long cycle culture at 7 Nos/m² densities and production was reverse at 3 Nos/m²and 5 Nos/m². But the differences in production between short cycle (two cycles) and long cycle culture at all three densities were insignificant.

Program Area: Variety and Species

Commodity: Shrimp

Objectives:

To study the ecology and production feasibility of different cropping patterns in Penaeus monodon culture system in the coastal ghers.
To study the impact of introduction of different fin fishes for increasing production from the coastal ghers.
To maximize production capacity and profitability from the coastal ghers.

Methodology:

The ponds were prepared by drying, liming (Quick lime: dolomite 1:1) @ 250 kg/ha of soil and then filled with the tidal water up to a depth of 1m. Water was treated with chlorine @ 20 ppm to disinfect water and kill all animalcules. Fermented molasses were applied to the pond water to develop colour of water to prevent penetration of sunlight and then fertilized with urea and TSP @ 25 and 30 kg/ha, respectively for quick development of colour of water and production of plankton. After production of sufficient plankton required quantity of PCR tested PL was acclimatized with the pond water and stocked to the in-pond nursery made of nylon net fastened in bamboo frame on 09 April 2014. In the nursery the stocked PL were fed with CP nursery feed. After 3rd week of nursery rearing, the juveniles were released to the whole pond by up-folding the nylon net of the nursery enclosure. In the grow-out ponds, the shrimp were fed with CP feed depending on the biomass of shrimp.

Achievement/Findings:

It is not possible to follow the intensified culture practice with higher stocking density by all categories of farmers due to lack of resource and fund. Also long cycle culture practice with higher stocking density needs supply of additional oxygen. Besides, there is more risk of invasion of viral disease if culture is lingered. Considering the need of increase in rate of production of shrimp, practice of two and even three short cycle production of shrimp at 5 Nos/m² density can be followed by the farmers. Practice of short cycle culture does not involve large amount fund and high technology. The return from one cycle can be used for the next cycle. This will capacitate the marginal and medium farmer to increase production from their ghers.
