Elimination of Chloramphenicol by Tiger Shrimp (Penaeus monodon) and White Shrimp (Litopenaeus vannamei)

White shrimp (Litopenaeus vannamei) is considered able to replace black tiger shrimp (Penaeus monodon) as a positive diversification. Excellence shrimp vaname (L. vannamei) is a high nutritional value, fast growth and able to use the water column as a place to live so it can be maintained with high stocking density. Natural feed (phytoplankton) can be stimulated through fertilization. The study was carried out at the Ghonebalano Coastal Fish Seed Center (BBIP), aiming to determine the effect of using different doses of urea and TSP fertilizer on the growth and survival of vaname shrimp (L. vannamei). The study used a Completely Randomized Design with three levels of combination treatment of fertilizer doses, namely treatment A urea 0.5 g/TSP 0.7 g; treatment B Urea fertilizer dose 0.7 g/TSP 0.9 g and treatment C dose Urea fertilizer 0.9 g/TSP 1.11 g. The results showed that the highest growth was obtained in treatment B i.e. 1.54±0.16 g/individuals, compared with treatment A (1.11±0.08 g/individuals) and treatment C (1.32±0.10 g/individuals). Survival in treatment A was 71.11±3.85%, treatment B was 73.33±6.67% and treatment C was 75.55±3.85%. Analysis of variance at the 95% confidence level (α0.05) showed that the administration of urea and TSP fertilizers differed significantly (0.05>0.03) on growth, but did not significantly influence (0.05<0.58) on the survival of vaname shrimp larvae.

Shrimp Culture

Shrimp culture has been developed during the last three decades and the production of farmed shrimp reached its peak. However, the shrimp production was decreased all over the World including in Asian Countries because of the mass mortality due to the outbreak of several diseases predominantly White Spot Syndrome Virus (WSSV) which caused extensive economic damage to the shrimp culture industry. Various Polyculture technologies of shrimp with shellfish, finfish or seaweeds have been implemented to reduce economic damages by mass mortality of shrimp. The present study was conducted with Tiger shrimp Penaeus monodon and Pacific white shrimp Litopenaeus vannamei through Polyculture operation to determine optimum stocking ratios for induction of best performance and highest production rates. Initially, the experiments were conducted with different ratios and combinations of stocking densities 1:1, 2:1 and 1:2 ratios of Penaeus monodon and Litopenaeus vannamei with control group feed with commercial feed, the other group certain Probiotic bacteria such as Bacillus licheniformis and Lactobacillus rhamnosus added in feed, the third group both the Probiotic bacteria and the addition of external Carbon source from sugarcane molasses in the form of Bioflocs for 100 days. To ascertain further interaction of ratios influence, 20:10, 20:12, 20:15 ratios of stocking and Monoculture experiments were conducted. In both the experiments the Survival rate, Final body weights, Weight Gain, Feed conversion ratio, Specific growth rates, Average daily growth rates, Protein efficiency ratio, and Productivity rates were significantly different (P<0.05) in all the different treatments both for P. monodon and L. vannamei. From the results obtained 20:10 ratio of P. monodon and L. vannamei was considered as the best ratio of stocking, which yielded the highest production rates in all the Control, Probiotic added and both Probiotic & Biofloc added groups. The results obtained in the present study clearly demonstrate that the rearing of taxonomically similar species with optimum stocking ratios seems to improve the efficiency of shrimp farming and substantially increasing the production rates. So, this polyculture of P. monodon and L. vannamei can be considered as an alternative approach towards the establishment of sustainable shrimp farming activity which will yield good economic returns.

The Pacific

White feces syndrome (WFS) is an emerging problem for penaeid shrimp farming industries in South East Asia countries. Outbreaks began in cultivated shrimp Penaeus (Penaeus) monodon, and Penaeus (Litopenaeus) vannamei and spread progressively worldwide, although the disease's cause was unknown. In 2011 a case definition for AHPND (as acute hepatopancreatic necrosis diseases) and white fecal syndrome (WFS) were reported. The presence of white feces floating on water and clinical symptoms include pale empty gut region, reduced growth, movable shell, and black discoloration. The pacific white shrimp, Litopenaeus vannamei, with the major shrimp cultivable species globally, is currently in danger by a severe disease- WFS, which causes serious losses worldwide. It has been confirmed that the causative agent of WFS/AHPND is a bacterium that is a pathogen - probably Vibrio parahaemolyticus. This bacterium currently reported has acquired plasmids that encode lethal binary toxins PirA/PirB causing rapid death of infected shrimp. Additionally, this plasmid acquired some virulence factor which is directly related to pathogenicity. Further rapid diagnostic tests for early detection of WFS/AHPND pathogens will promote the production of hatchery and pond maintenance and contribute to the long-term explication of the disease's various aspects.
