The illusion of plenty: hyperstability masks collapses in two recreational fisheries that target fish spawning aggregations
Fisheries that target fish spawning aggregations can exhibit hyperstability, in which catch per unit effort (CPUE) remains elevated as stock abundance declines, but empirical support is limited. WeExpand
Operationalizing the social-ecological systems framework to assess sustainability
The case of small-scale fisheries in Baja California Sur, Mexico is used to identify distinct SES regions and test key aspects of coupled SESs theory, highlighting the importance of integrative, coupled system analyses when implementing spatial planning and other ecosystem-based strategies. Expand
Phylogenetic perspectives on the evolution of functional hermaphroditism in teleost fishes.
This work strongly supports sexual lability within teleost fishes and confirms evolutionary theories of sex allocation in this group of vertebrates. Expand
Large Recovery of Fish Biomass in a No-Take Marine Reserve
The recovery of fish biomass inside CPNP has resulted in significant economic benefits, indicating that community-managed marine reserves are a viable solution to unsustainable coastal development and fisheries collapse in the Gulf of California and elsewhere. Expand
Fishery and Biological Implications of Fishing Spawning Aggregations, and the Social and Economic Importance of Aggregating Fishes
This chapter explores the fishery and biological implications of ­exploiting aggregating marine fishes, their general importance to subsistence, commercial, and recreational fisheries and theExpand
Spawning patterns in the leopard grouper, Mycteroperca rosacea, in comparison with other aggregating groupers
Leopard grouper behavior patterns were unusual in that spawning aggregations persisted for extended periods, spawning was not synchronized with the lunar cycle, and adults aggregated during non-spawning periods, increasing the vulnerability of the species to overfishing. Expand
A Phylogenetic Test of the Size‐Advantage Model: Evolutionary Changes in Mating Behavior Influence the Loss of Sex Change in a Fish Lineage
It is shown that the loss of sex change within a lineage of reef fishes is influenced by evolutionary changes in two traits related to their mating behavior: mating group structure and sperm competition intensity. Expand
Evidence of gonochorism in a grouper, Mycteroperca rosacea, from the Gulf of California, Mexico
The sexual pattern and sexual development of the leopard grouper, Mycteroperca rosacea, were investigated from 483 specimens collected from the Gulf of California, Mexico and found the gonochoric sexual pattern is likely influenced by its group-spawning mating system. Expand
Courtship and Spawning Behavior in the California Sheephead, Semicossyphus Pulcher (Pisces: Labridae)
Recording the courtship and spawning behavior of a protogynous fish, the California sheephead, Semicossyphus pulcher, throughout their spawning season illustrates the need for creating management strategies that better complement the unique life histories of marine fishes with alternative reproductive strategies. Expand
Spatio-temporal dynamics of a fish spawning aggregation and its fishery in the Gulf of California
Results of this study demonstrate the benefits of combining GPS data loggers, fisheries data, biological surveys, and cooperative research with fishers to produce spatio-temporally explicit information relevant to the science and management of fish spawning aggregations and the spatial planning of marine reserves.
