Length‐Based Spawning Potential Ratio Assessment of Key Species From a Remote Recreational Fishery at Diego Garcia, Indian Ocean

Fisheries Management and Ecology, EarlyView.
ABSTRACT Recreational fisheries in remote regions often operate under limited regulation and data availability, presenting challenges for sustainable management. Diego Garcia, located within the Chagos Marine Protected Area, hosts a unique recreational reef fishery embedded within a highly protected environment. We assessed the stock status of five key

The state of knowledge on four families of Syngnathoidei fishes (Teleostei: Syngnathiformes): Aulostomidae, Centriscidae, Fistulariidae and Solenostomidae

Journal of Fish Biology, EarlyView.
Abstract Knowledge on the ecology and life‐history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. However, such data have never been collated for four of the five families in the suborder Syngnathoidei—the close relatives of the better‐studied ...
