Thai Government Hatchery Utilizes Rotomolded Parts to increase populations of the Blue Crab Ocean’s natural resources have been dramatically depleted in recent decades due to over-fishing and indiscriminate catches. This causes a disruption in the natural life cycle of marine animals and leads to reduced marine life population. Without some type of human intervention, it is unlikely that nature can heal itself back to the same sustainable level. In this issue, we will discuss a case study about a government hatchery center that utilizes rotomolded tanks and bins to increase the population of ocean blue crabs. This hatchery is located in Chantaburi, a coastal province in eastern seaboard of Thailand. It was found about 23 years ago by the vision of late King Rama 9.
Blue crab populations in the Gulf of Thailand have drastically decreased over the years. Blue crab is a local marine life commonly found worldwide. It is quite a popular delicacy both in homes and restaurants. There is also a large commercial fishing of blue crabs for its meat to be processed as frozen seafoods. As a result, blue crab populations in the Gulf of Thailand have drastically decreased over the years. In the natural environment, blue crabs take about 4-5 months to grow and mature into adults. One mother crab can produce about 300,000-700,000 eggs but less than one percent (or 3,000 crabs) will survive and grow into adulthood. In the past,
