Toxicity of Drilling Waste and Its Impact on Gill Structure of Post Larvae of Tiger Prawn (Penaeus monodon)
نویسندگان
چکیده
The study to evaluate the toxicity of used drilling muds (drilling wastes) and their impact on gill structure of the post larvae of tiger prawn Penaeus monodon has been done. The results showed that the 96 h LC50 of used drilling muds ranged from 30740 and 78271 ppm SPP. All toxicity values considered to be above the standard of Indonesian government (LC50≤30000 ppm SPP). Histological observation showed that only haemocytic congestion in the gill lacunae of post larvae was recorded. The gill lacunae exposed to high concentration of drilling waste (62500 ppm SPP) were reduced or absent.

As white spot syndrome virus (WSSV) can be highly pathogenic in penaeid shrimp, various feed supplements have been tested to help to protect farmed shrimp against WSSV disease. Here a polysaccharide extract from Halophila ovalis (HO) seagrass was added to feeds at concentrations of 0.25, 0.5, and 1.0 g[a1] /kg to assess its ability to protect Black Tiger shrimp (Penaeus monodon) against WSSV ch...

An in vitro study of the attachment of Vibrio pathogens to tissues of the giant tiger prawn Penaeus monodon (Fabricius, 1798) was carried out using species-specific and genus-specific monoclonal antibodies with indirect FITCimmunofluorescence microscopy. The attachment of V. alginolyticus and V. parahaemolyticus to different tissues was always stronger than the attachment of V. anguillarum, and...
