This increases the loss of mangroves due to shrimp farming. 
  • The continued degradation of mangrove resources is most likely due to a lack of efficient regulation of the resources. 
  • Despite the passage of legislation, a combination of exclusions for small-scale exploitation and a lack of enforcement gave the false impression that mangrove forests were effectively free resources. 
  • Fortunately, the problem is becoming more widely recognized, and effective steps are being done to prevent harmful consequences.

This was particularly true for farms located near estuaries. 
  • Compliance with effluent water quality criteria established by the Global Aquaculture Alliance (GAA) will be difficult if the intake water is already polluted.
  • Sedimentation zones for both intake and discharge waters, erosion management in supply and discharge canals, and the use of seawater when available are all design and construction approaches for lowering effluent pollution potential. Less water exchange, improved fertilization processes, good feed management, and the installation of measures to prevent mechanical aerators from eroding pond bottoms and sides are all good pond management practices for enhancing effluent quality.

In effect, the reefs are getting sunburned, which leads to coral bleaching.
  • Tannic acid is a naturally occurring chemical obtained from plants that discolors water and contributes in the preservation of coral reefs due to its structure in water.
  • Coral bleaching may be devastating, with the potential to wipe out entire ecosystems, as fauna around the coral loses their ability to find food and migrates or dies, leaving empty underwater landscapes.

Water pollution is largely caused by waste from livestock and food farms, including shrimp farming. Agricultural industries are also the biggest consumers of freshwater. Rain transports fertilizer, insecticides, and animal waste from fields to bodies of water like lakes and rivers. 
    • Environmental concerns: Poor water quality unquestionably affects the environment in a negative way because it impacts plant and animal life. Plants rely on clean groundwater to sustain life, but pollutants lower the quality and kill plants. Additionally, animals drink freshwater from ponds, lakes, rivers, and the like. Those animals contract any disease in the water. This leads to the spread of illness in animals and death.
