Significant punctiform and diffuse pressure in upper Crasna river basin.
Journal Title: Aquaculture, Aquarium, Conservation & Legislation - International Journal of the Bioflux Society - Year 2011, Vol 4, Issue 2
Abstract
The preservation of healthy ecosystems which are biological valuable, whose actual status is convenient, as well as the improvement or transformation of those partially or heavily modified by anthropic interventions, should be targeted to achieve objectives of the ecological balance of any watercourse. The pressure on aquatic environment are generated by agglomerations, industry and agriculture, but also by hydromorphological area. In the upper of the Crasna basin the level of nutrient impurification due to human agglomeration sets a “sensitive” character for Crasna area and ranks the Crasna river in a lower class of quality. IPPC and NON IPPC industry generates dangerous substances, especially those on List II, which establishes the low state of the Crasna river. Dangerous substances cause toxicity, persistence and bioaccumulation in the aquatic environment. Impact of non-priority and priority pollutants, in terms of environmental impact is not distinct, therefore there is a tendency to pay attention to priority poluttants, even if non-priority substances create the gratest damages. Lack of clean technologies or non compliance with Best Available Technologies is the main cause of surface resource contamination by dangerous substances.

Evidence of WSSV transmission from the rotifer (Brachionus plicatilis) to the black tiger shrimp (Penaeus monodon) postlarvae and means to control rotifer resting eggs using industrial disinfectants
Rotifers are considered possible vectors of the white spot syndrome virus (WSSV) and have been implicated in its recurrence in pond-cultured shrimp. However, direct evidence of the transmission and the pathogenicity of t...
