Disease and pollution resulting from aquaculture

To meet the demand for fish and prevent the depletion of fish stocks, marine organisms are farmed for human consumption. Aquaculture is associated with several impacts on the aquatic environment: the spread of diseases among fish, the destruction of wetlands and mangroves, and the decline of natural fish populations due to the escape of non-native fish from aquaculture. Aquaculture is also associated with severe water pollution from the discharge of waste water, the use of commercial feed, the accumulation of fish faeces, the decomposition of dead fish and the improper disposal of fish waste, which threatens the survival of other aquatic species.

In response to global demand for shrimp, shrimp farming has expanded rapidly in Bangladesh, where conditions such as climate and water availability are favourable for the industry. However, shrimp farming has significant negative environmental impacts in the country. These include mangrove destruction, sedimentation, loss of biodiversity, saltwater intrusion and pollution. Coastal ecosystems are particularly affected by the unplanned expansion of shrimp farming.
