Removal of heavy metals and suspended solids from shrimp culture wastewater in Bushehr Province, using cold ‎plasma technology

In less intensive shrimp culture systems, polychaetes are known to be a major food item of several penaeid species. Under these conditions, very little is known about their population dynamics and the possible interactions with penaeid predation and artificial feeding. This work examined the effects of Penaeus subtilis, predation, stocking density and supplemental feeding on the population dyna...

Cyanobacterial diversity from two geographical areas of Baja California Sur, Mexico, were studied: Bahia Concepcion, and Ensenada de Aripez. The sites included hypersaline ecosystems, sea bottom, hydrothermal springs, and a shrimp farm. In this report we describe four new morphotypes, two are marine epilithic from Bahia Concepcion, Dermocarpa sp. and Hyella sp. The third, Geitlerinema sp., occu...

SL2/PU!culture is of central importance to the fisheries sector in Bangladesh. It grew from next to nothing in the early 1970s to contribute about 11% of total exports in the mid-1990s (DOF 1995). No other primary commodity enjoyed such spectacular growth in post-independence Bangladesh. Although shrimp farming has had a significant impact on the economy of Bangladesh, it has had high environme...

In India, the shrimp culture today has industrialized into an improved farming system and is evolved day by day into a well talented for the management. Present work was carried out in the shrimp Litopenaeus vannamei culture in Sattanathar aqua farm in the east coast of Nagai District, Tamil Nadu, India from April 2015 to August 2015. Water quality parameters for the entire culture ponds was pr...

Aquaculture is the fastest growing food sector globally and is established itself as high protein resource to fulfill the food demand since the natural resources exhibits over exploitation. But, presently, the biggest problem faced by the aquaculture industry worldwide is diseases caused due to various biological and non-biological agents. Among the groups of microorganisms that cause serious l...

Lack of shrimp cell lines has hindered the study of pollutants which adversely affects shrimp health and its export value. In this context a primary haemocyte culture developed from Penaeus monodon was employed for assessing the cytotoxicity and genotoxicity of two heavy metal compounds, cadmium chloride and mercuric chloride and two organophosphate insecticides, malathion and monocrotophos. Us...

Problem statement: The present work was attempted to evaluate the probiotic activity of Bacillus spp. in shrimp health management. Approach: Penaeid culture ecosystem as a confined environment with huge inputs always encourages the proliferation of pathogenic bacteria like Vibrios. Results: From the present study and earlier reports it is understood that these pathogens alone or combine with vi...

RNA interference (RNAi) has recently become a promising strategy for therapeutic of several viral diseases including those in the black tiger shrimp Penaeus monodon. However, the protein components that play role in RNAi in P. monodon have not yet been identified. Here, we report the cloning and functional characterization of a cDNA encoding Argonaute, a principal constituent of RNAi pathway in...
