Mussel farming

The mussels are bivalve molluscs typically inhabiting the territorial to shallow sub littoral zones of the coastal areas

Site suitability evaluation for bivalve mariculture in Maharashtra

The coastal stretch of Konkan Maharashtra is endowed with large number of west flowing rivers forming productive estuaries and creeks fringed by mangrove vegetation. The coastline stretching across the districts of Raigad, Ratnagiri and Sindhudurg are marked by the presence of narrow creeks offering sheltered areas for aquaculture activities. Considering the potential for expanding bivalve farming in Maharashtra, surveys for selecting suitable sites for coastal farming were conducted from 5th to 8th October, 2013 covering Thane,Raigad, Ratnagiri and Sindhudurg districts

Mussel Farming Methods and the Prospects and Problems in India

Mussel farming has a long history that dates back to the thirteenth century. Mussels are farmed in many areas of the world with the most common species cultured being the blue mussel, Mytilus edulis. The main producers of mussels are countries such as China, Korea, Spain, Netherlands, Denmark, France and New Zealand. In 2012, 1.829 million tonnes of mussels were produced worldwide valued at 2.053 billion US Dollars (FAO). The Indian mussel production is relatively small and the production is around 10,000 tonnes for the past few years

Optimal Inventory Policy in a Closed Loop Supply Chain System with Multiple Periods

Purpose: This paper aims to model and optimize the closed loop supply chain for maximizing the profit by considering the fixed order quantity inventory policy in various sites at multiple periods. Design/methodology/approach: In forward supply chain, a standard inventory policy can be followed when the product moves from manufacturer, distributer, retailer and customer but the inventory in the reverse supply chain of the product with the similar standard policy is very difficult to manage. This model investigates the standard policy of fixed order quantity by considering the three major types of return-recovery pair such as commercial returns, end- ofuse returns, end –of- life returns and their inventory positioning at multiple periods. The model is configured as mixed integer linear programming and solved by IBM ILOG CPLEX OPL studio. Findings: To find the performance of the model a numerical example is considered for a product with three Parts (A which of 2nos, B and C) for 12 multiple periods. The results of the analysis show that the manufacturer can know how much should to be manufacture in multiple periods based on Variations of the demand by adopting the FOQ inventory policy at different sites considering its capacity constraints. In addition, it is important how much of parts should be purchased from the supplier at the given 12 periods Originality/value: A sensitivity analysis is performed to validate the proposed model two parts. First part of the analysis will focus on the inventory of product and parts and second part of analysis focus on profit of the company. The analysis which provides some insights in to the structure of the model.Peer Reviewe

Overview of Bivalve fisheries of India

Bivalves are commercially important molluscs belonging to the Class Bivalvia (Lamellibranchia or Pelecypoda), which is the second largest Class under the Phylum Mollusca. They are bilaterally symmetrical, laterally compressed molluscs, with extensive mantle lobes which secrete a single shell composed of two valves. Bivalves are reported to have originated in the euryhaline w a rm shallow coastal waters prior to their gradual invasion to estuarine, brackish, fresh and all the reaches of marine, ecosystems. Although, none have invaded the land, the bivalves are more successful in marine and a few species are found in freshwater habitats. Nearly 652 species of marine bivalves are reported from India, of which 88 species are endemic to Indian waters

Provisional guidelines for bivalve farming in India with emphasis on meeting hygiene and public health requirements

Bivalve molluscs such as clams, mussels, oysters and scallops are prime seafood that contribute to capture and aquaculture production in many countries. Globa bivalve aquaculture production has increased two-fold from 7.08 to 14.72 million tons during 1995-2015. While production has increased, the share of bivalves entering the international trade is relatively small, due to the stringent regulations on their imports associated with the food safety issues in major markets. The regulatory regime for bivalve products, under live or processed category, varies with the importing country
