  2. DEFINITION • Concept where different species are grown together. • Invertebrates and/or plants recycle the nutrients that are lost from the culture of the other species. • Different from polyculture. • Can be used in almost all aquaculture containers (sea and land)

  3. MODEL EXAMPLE

  4. IMTA SYSTEM DESIGN • Require the selection, arrangement and placement of various components or species. • Should provide economic and environmental sustainability. • Reduce eutrophication and increase economic diversification by converting by products and uneaten feed from feed organism to harvestable crops.

  5. SPECIES SELECTION • Complementary roles with other species in the system. • Adaptability in relation to the habitat. • Market demand for the species and pricing as raw material. • Ability to provide both efficient and continuous bio mitigation.

  6. THE ADVANTAGES OF IMTA • Improving the biodiversity. • Decrease in waste outputs from overall farming activities. • More environmentally sustainable farming operations. • No or less reliance on fish meal . • Improving local economy • Increased profits through diversification .

  7. DISADVANTAGES OF IMTA • Lower productivity than fed monocultures. • Food safety concerns (coliforms and parasites) • Public perception issues. • Species limitations (especially in New Zealand) • Requires good management to balance inputs and nutrient flows.

  8. THE PROSPECTS OF IMTA IN BANGLADESH • Coastal aquaculture sector particularly vulnerable to climate change. • Different climatic variables (cyclone, drought, flood, rainfall, salinity, sea level rise, and sea surface temperature) have had adverse effects on land-based prawn and shrimp farming. • Open-water IMTA could be developed to cope with the challenges. • Positive view of developing IMTA prospects due to environmental and economic benefits.

  9. THE PROSPECTS OF IMTA IN BANGLADESH • Adoption could reduce ecological effects of shrimp culture on the Sundarbans mangrove forest as well as reduce pressure from capture fisheries. • Has great potential for increasing food production, income, and livelihood opportunities. • Increase export earnings and economic growth of the country .

  10. CHALLENGES • Higher investment and higher level of technology • Difficulty in co-ordination of management • Difficulty in implementation

  11. What do you mean by SWOT analysis? • SWOT (strengths, weaknesses, opportunities, and threats) analysis is a framework used to evaluate a company's competitive position and to develop strategic planning. SWOT analysis assesses internal and external factors, as well as current and future potential.
