Feasibility of a Close-Kin Mark-Recapture for Stock Assessment of Indian Ocean Swordfish (Xiphias gladius)

Fishes
The Indian Ocean Tuna Commission (IOTC) manages swordfish, Xiphias gladius, a species of high economic importance in the Indian Ocean. Current stock assessments rely on catch per unit effort indices, which can be biased, complicating reliable abundance ...
