For example, shrimp farming has led to substantial mangrove deforestation in countries like Thailand, impacting biodiversity.

  2. Reduced Wild Fish Populations:
    Reduced wild fish populations happen when farmed fish compete with or prey on wild species. Overfishing of specific species for feed leads to declines in their populations. The IUCN reports that over 60% of fish stocks are fully exploited or overfished, contributing to the decline of marine biodiversity. A notable case is the overfishing of small fish like menhaden, which are critical for the diet of larger marine animals.

  3. Disease Spread:
    Disease spread refers to the transmission of pathogens from farmed fish to wild populations. Fish farms often harbor diseases due to high stocking densities and poor water quality. According to a study by the World Wildlife Fund (WWF) in 2015, pathogens from aquaculture can infect wild fish, disrupting local ecosystems and leading to mass die-offs. For example, sea lice from farmed salmon are known to infest wild salmon populations in the Pacific Northwest, posing a threat to their survival.

  4. Genetic Pollution:
    Genetic pollution occurs when farmed fish interbreed with wild populations, compromising their genetic integrity. This can lead to the introduction of genes that may reduce the fitness of wild fish. Research published in the journal Conservation Biology suggests that farmed fish are often less adapted to local conditions, which can diminish the resilience of wild populations. An illustrative case is the escape of farmed Atlantic salmon into Pacific waters, threatening native salmon species.
