Group 8: EIA Class Activity
Main issues
of Shrimp Farming projects in Bangladesh
Environmental
Loss of land of natural resources
excessive saltwater causing infertile land
river erosions
loss of other marine animals (source of foods)
Social Impacts-
malnourishment
poverty
uneducated about the proper ways of catching shrimp without endangering other marine animals
food poisoning and disrupting the food chain due to the presence of endosulfan in the water resources
violence by the owners of shrimp farmings
sexual harrassment
Major issues
of Shrimp farming projects in Malaysia
Competitiveness
High cost of local labour
Competition in export markets
Diseases
White spot syndrome virus
Vibrio
Conflicts of Interest
Land for expansion has become more expensive and difficult to acquire
Environmental Impacts
Soil quality declines
Pond preparation
Drying pond until the surface cracks and then scraping the dried organic matter follows by flushing of the pond with water jets causes environmental pollution
Clearing of the mangroves area
Physico-chemical parameters included in an aquaculture project
Water Quality
Surface Water Quality
Ground Water Quality
Waste disposal and chemical safety
Identification of any chemicals that might presence in the site of projects
Application of proper handling and storage procedures and protocols
Disposal of waste in a proper management
Flora (Vegetation)
Identify any rare or endangered plant species
From IUCN red list
Identify any valued population
Example: Timber
Any plant that is important for specific animal's habitat or foods
Inventory of terrestrial and aquatic plants
List out total species diversity
Population and density data for vegetation species
Fauna (Animals)
Inventory of terrestrial, aquatic, avifauna and bats
Species diversity of animals according to taxa
Population and density of animals
Permanent or migratory population
Knows the species
Know their routes
Habitats
Niches
Identification of any rare and endangered species
Land ownership
Belong to native: Ask permission and have proper documentation, paperwork
Belong to government: Apply for land , have proper documentation after approval
Terrain analysis
Type of soil: Clay or Sandy clay soil for good water retention. Clay loam or silty clay loam for good pond fertility.
Soil suitability: Consider soil quality to avoid accidents. Soil can anchored the dam to avoid dam from slipping away. Ability of soil to resist water saturation.
Water canals: Make sure building of water canal does not cause soil erosion.
Proper soil and pond management:
Uses of organic matter to block soil pores and reduce water loss. .
Control pH of soil to avoid endangering the health of fish
