### Threats

The primary threats to fish stocks are the ongoing [habitat destruction](/wiki/Habitat_destruction "Habitat destruction") brought on by the use of [dynamite](/wiki/Dynamite "Dynamite") and dragnets (beach seine and similar nets), as well as the overfishing of keystone species as a result of an increase in the population of fishers and collectors (driven by demand) who are allowed free entry into and around TMRs. This investigation made it very evident that the majority of fishing occurs outside of the Bays, on coral reefs, seagrass beds, and/or nearby deep waters. Where there is a combination of or interactions between mangroves, coral reefs, and seagrass beds, fish aggregations happen. Mangrove crabs, prawns, octopus, lobsters, clams, sea cucumbers, and shelled mollusks are a few of the edible invertebrates that can be found in TMRs.


How can we mitigate the effects of habitat destruction on fish stocks?
