Industrial Seawater Cooling Systems under Threat from the  Invasive Green Mussel Perna viridis

The green mussel Perna viridis, native to the Asia-Pacific region, has been introduced to other regions such as the Caribbean, Japan and North and South America. It is a large, commercially important species, widely cultivated and harvested in Southeast Asia, but is also considered an invasive species elsewhere, capable of replacing native species. As a fouling organism in intake systems of coastal power plants, it causes flow blockage and loss of cooling efficiency. Mussel colonization during peak settlement season can exceed 35,000 individuals/m2 and biomass can exceed 100 kg/m2. They can withstand wide fluctuations in temperature and salinity. Previous work has shown that a conventional biofouling control measure such as chlorination is not very effective against these bivalves, unless applied continuously for extended periods of time. We require more efficient, environmentally compatible methods of biofouling control. The paper discusses these issues in the context of the perceived invasion potential of P. viridis.

Suitable Site

Green mussel is one of important species cultured in Lada Bay, Pandeglang. To provide a necessary guidance regarding green mussel mariculture development, finding suitable site is an important step. This study was conducted to identify suitable site for green mussel mariculture development using geographic information system (GIS) based models. Seven important parameters were grouped into two submodels, namely environmental (water temperature, salinity, suspended solid, dissolve oxygen, and bathymetry) and infrastructural (distance to settlement and pond aquaculture). A constraint data was used to exclude the area from suitability maps that cannot be allowed to develop green mussel mariculture, including area of floating net fishing activity and area near electricity station. Analyses of factors and constraints indicated that about 31% of potential area with bottom depth less than 25 m had the most suitable area. This area was shown to have an ideal condition for green mussel mariculture in this study region. This study shows that GIS model is a powerful tool for site selection decision making. The tool can be a valuable tool in solving problems in local, regional, and/or continent areas.

Background: Green mussel Perna viridis is a bivalve mollusc which is native to the Indian coast and can be found in the Indo-Pacific as well as Asia-Pacific regions. This study evaluates the P. viridis foot (PVF) as a source of an anti-inflammatory peptide. Objective: To characterize and evaluate the possibility of pro-inflammatory cytokines, nitric oxide (NO) as well as cyclooxygenase (COX)-2 reduction in RAW264.7 cells and to analyze functional aspects of the derived peptide from PVF. Materials and Methods: The PVF was hydrolysed with different enzymes and the antiinflammatory activity of hour hydrolysates were evaluated using HRBC Membrane Stabilization (HMS) against hypotonicity induced haemolysis and Albumin Denaturation (AD) inhibition from induced heat assays. Later, the active hour hydrolysate was separated by ultrafiltration and purified using Size-Exclusion Chromatography (SEC). Further, the purified peptide’s sequence was identified using LC-MS/MS and functional properties were determined. Also, the peptide was observed for its anti-inflammatory effects in lipopolysaccharide (LPS)-stimulated RAW264.7 cells for pro-inflammatory cytokines, NO production and COX-2 activation. Results: Among the four enzymes 6th hour alcalase hydrolysate exhibited potent anti-inflammatory activity and was sequentially fractioned with molecular weight cut-offs; further active fraction (30- 10 kDa) was purified. The active peak-II was identified as EGLLGDVF (849.435 Da) and exhibited decent functional aspects. The peptide successfully reduced the production of pro-inflammatory cytokines, NO and COX-2 activation; and down-regulated the iNOS and COX-2 protein expression in LPS-stimulated RAW264.7 cells. Conclusion: Our study indicates that EGLLGDVF derived from PVF has potential antiinflammatory applications applicable in food and pharmaceutical industries.

Abstract Development of mollusc culture as a livelihood option for rural coastal fisher folk in Bangladesh is now being considered. All the cultural requirements of molluscs are available in Bangladesh. It has been estimated that there are about 450 species of molluscs, but the two most commercially important species (green mussel, Perna viridis; oyster, Crassostrea sp.) have been chosen to assess their potential for aquaculture. The proposed site (St. Martin's Island) is most suitable for the species being considered. Although not locally consumed, molluscs have an international market. Resource personnel, skilled and semi-skilled as well as institutional facilities to implement mollusc culture are also present in the country. Therefore, it can firmly be stated that Bangladesh has great potential for mollusc culture.
