Mangrove forests serve as vital nursery habitats that protect juvenile fish from predators primarily through their complex physical structure.12

These salt-tolerant trees form dense, tangled thickets of roots that create an intricate, often impermeable environment. This structural complexity provides a secure refuge where young fish can hide from larger predators that are unable to navigate the dense root systems. In addition to this physical protection, these areas offer abundant food sources, allowing juveniles to grow and develop before they eventually migrate to the open ocean. By providing these safe hatchery sites, mangroves play an essential role in supporting biodiversity and maintaining the health of local fisheries.321
