Effects of Probiotics on Growth and Survival of Shrimp (<i>Penaeus monodon</i>) in Coastal Pond at Khulna, Bangladesh

Abstract

The study was carried out for 138 days to know the growth and survival rate of P. monodon by applying probiotics in Gazi Fish Culture Ltd. Dacope, Khulna, Bangladesh. Six experimental ponds (4000 m 2 in size i.e. one acre) were selected of which three were probiotic ponds and three were controlled. After pond preparation, PL 15 (average weight of each 4.75±0.09 g) was stocked at the rate of 13 per m 2 following polymerase chain reaction (PCR) test. CP NASA shrimp feed was used during the study period. Transparency, salinity, pH, dissolved oxygen (DO), temperature, total Ammonia Nitrogen (TAN) were recorded by standard measurements. The average final body weight of the harvested shrimp is 37.67±1.15 g in probiotics ponds and 27.33±0.58 g in controlled ponds and the difference was significant (P < 0.01) between these two productions. The average survival rate was 90.67±1.15 % in probiotic pond and 71.00±3.0 % in controlled pond. The average daily gain (ADG) in weight was 0.27±0.01 g and 0.19±0.01 g in probiotic and controlled ponds, respectively. The result showed that probiotic plays an important role in maintaining water quality parameters, soil quality and health management as well as increases the growth and survival of shrimp.

Evaluation of Potential Probiotics Bacillus subtilis WB60, Pediococcus pentosaceus, and Lactococcus lactis on Growth Performance, Immune Response, Gut Histology and Immune-Related Genes in Whiteleg Shrimp, Litopenaeus vannamei

“…The application of probiotics in shrimp diets have shown beneficial effects on the growth [23], immune response [24], and disease resistance [25]. Among the probiotics used in the present study, B. subtilis WB60, which was isolated from the intestine of juvenile Japanese eel Anguilla japonica, was reported as a potential probiotic, as well as an antibiotic replacement in the diet [18].…”

Investigation of Phytoplankton and Physico-chemical Parameters in Nursery, Growout and Broodstock Ponds

“…Jhingran [11] quoted that the suitable temperature range for production of phytoplankton in tropical ponds were between 18.3 to 37.9°C. During the study period water temperature was found to vary from 15 [19] recorded temperature 18.3°C to 35.1°C in fish ponds of BAU and BFRI; Hasan [20] recorded water temperature 18.2°C to 34.2°C in Chalan Beel; Hossain et al [21] recorded temperature 27°C to 33°C in coastal ponds. The statistical test (Tuckey) shows that the temperature does not differ significantly among the ponds except for T 1 and T 3 in January which differs significantly at 5% level (Table 1).…”

Effects of Seasonal variation on Growth Performance of Mirror carp (Cyprinus carpio Ver. specularis) in Earthen Nursery Ponds

“…In warmer environment fish have a longer growing season and faster growth rate but tend to have a shorter life Hossain span than in cool water. High water temperature increases the metabolic rate, resulting in increased food demand Hossain et al, 2013a). Although, fish can generally function in a wide range of temperature, but they do have an optimum range, as well as lower and upper lethal temperature, for various activities (Beschta et al, 1987).…”
