Better Management Practices (BMP):Management practices aimed at improv<strong>in</strong>g the quantity, safety and quality <strong>of</strong> products tak<strong>in</strong>g <strong>in</strong>to considerationanimal health and welfare, food safety, environmental and socio-economical susta<strong>in</strong>ability. BMP’s aremanagement practices, and implementation is generally voluntary; they are not a standard for certification. Theterm “better” is preferred rather than “best” because aquaculture practices are dynamic and cont<strong>in</strong>uouslyimprov<strong>in</strong>g. The core technology around which the BMPs were developed was shrimp health management. Thespecific ones <strong>in</strong>cluded preventive measures without resort<strong>in</strong>g to use <strong>of</strong> chemicals, ma<strong>in</strong>tenance <strong>of</strong> the quality <strong>of</strong>water and substrate, and proper nutrition and feed<strong>in</strong>g. The broad practices <strong>in</strong>cluded reduc<strong>in</strong>g or cop<strong>in</strong>g with therisks <strong>of</strong> pathogens be<strong>in</strong>g <strong>in</strong>troduced <strong>in</strong>to the farms with such practices as synchronized water <strong>in</strong>take anddischarge, simultaneous cropp<strong>in</strong>g, putt<strong>in</strong>g up and observ<strong>in</strong>g early warn<strong>in</strong>g signs <strong>of</strong> disease onset, learn<strong>in</strong>g fromeach other, assur<strong>in</strong>g product quality and safety and, overall, act<strong>in</strong>g collectively <strong>in</strong> their own <strong>in</strong>terest.Key BMPs developed and implemented through participatory approach are:Good pond/water preparation- All the society farmers plan to prepare pond as per crop plann<strong>in</strong>gschedule. Wherever possible the mach<strong>in</strong>eries like tractors and earth mov<strong>in</strong>g equipments are hiredon contract basis for the whole society thus reduc<strong>in</strong>g cost and mak<strong>in</strong>g it possible for all farmers toprepare the ponds <strong>in</strong> time for the crop.Good quality seed selection- Society farmers purchase through contract hatchery seedprocurement system where all the group farmers purchase quality seed for whole group.Feed management- All society farmers use good quality commercially produced feed. FCR ismonitored through record keep<strong>in</strong>g all ponds <strong>of</strong> the society.Water quality management- Each society sets up basic water quality analysis lab at farm site tomonitor parameters like dissolved oxygen, pH and Alkal<strong>in</strong>ity.Pond bottom monitor<strong>in</strong>g- Dur<strong>in</strong>g weekly meet<strong>in</strong>gs the condition <strong>of</strong> all society ponds are discussedand where necessary farmers are asked to take actions to improve pond bottom condition.Health monitor<strong>in</strong>g/Biosecurity- No dra<strong>in</strong><strong>in</strong>g or abandon<strong>in</strong>g <strong>of</strong> disease affected stocks. Farmergroups are encouraged to discuss common actions that can be taken dur<strong>in</strong>g disease outbreaks toavoid spread<strong>in</strong>g <strong>of</strong> disease from one farm to another.Food safety- All society farmers agree not to use any harmful/banned chemicals like pesticides andantibiotics.Record ma<strong>in</strong>tenance/Traceability- All farmers <strong>in</strong> the society agree to ma<strong>in</strong>ta<strong>in</strong> pond managementrecord book which are provided by NaCSA.Better Harvest and post-harvest Practices- Through l<strong>in</strong>k<strong>in</strong>g <strong>of</strong> societies to local processors stepslike quick harvest<strong>in</strong>g dur<strong>in</strong>g early morn<strong>in</strong>g hours, chill kill<strong>in</strong>g <strong>of</strong> harvested shrimp and quicktransport to process<strong>in</strong>g plant can be implemented.Environmental awareness- Improved environmental awareness about mangroves, pollution andwaste management among society farmers. Steps <strong>in</strong>itiated aga<strong>in</strong>st pollut<strong>in</strong>g <strong>in</strong>dustries along thecommon creeks through collective efforts <strong>of</strong> farmers.Dissem<strong>in</strong>ation <strong>of</strong> BMPs:119
