TL;DR: In this article, the authors compared catch per unit effort (CPUE) and fishing effort data in HSI modeling and concluded that a fishing effort-based HSI model performs better in defining optimal habitats for neon flying squid.

TL;DR: Any evaluation of harvest policies for forage fish needs to include issues, and models tailored for individual species and ecosystems are needed to guide fisheries management policy.

TL;DR: Fish assemblages inhabiting two types of mangrove-lined shoreline that encompass Biscayne Bay were examined using a visual 'belt-transect' census method, suggesting that these shoreline habitats play varying ontogenetic and trophic roles, depending on location, season and fish species.
Abstract: Biscayne Bay is a shallow subtropical lagoon on Florida's southeastern coast that is bordered to the west by the mainland and to the east by barrier islands and keys. Fish assemblages inhabiting two types of mangrove-lined shoreline that encompass the Bay were examined using a visual 'belt-transect' census method over four consecutive seasons. Several significant differences were evident between shoreline habitats in terms of fish species composition, taxonomic richness and taxon-specific densities; seasonal changes and fish size-structure differences were few. The mangrove shorelines along the mainland (ML) consistently harbored less fish taxa than those on the leeward side of the islands and keys (LK), but harbored higher densities of several euryhaline forms (i.e., killifishes and livebearers). Densities of fishes that are typically associated with coral reef habitats (i.e., snappers and grunts) tended to be higher within LK vs ML mangrove shorelines, but there were exceptions (e.g., great barracuda, Sphyraena barracuda). For five fish species, length-frequency distributions were compared between the Bay's mangrove shorelines and nearby coral reef habitats. These data comparisons lent partial support to an ontogenetic 'mangrove-to-reef' migration model for only two of the five species examined. Results suggest that these shoreline habitats play varying ontogenetic and trophic roles, depending on location, season and fish species Biscayne Bay's mangrove shoreline fish assemblages appear to reflect: (1) proximity of the mangroves that they occupy to offshore reef habitats; (2) salinity regime along the shoreline; and (3) water depths within the mangrove forest interior. The fish assemblage information collected here may serve as a 'baseline' in future assessments of fishing impacts or the effects of other anthropogenic changes to Biscayne Bay and its watershed.

TL;DR: In this paper, a suite of active management interventions must be considered to restore the spawning biomass of severely over-exploited populations, such as restocking no-take zones with hatchery-reared juveniles, aggregating wild individuals in no take zones, and developing small enterprises to rear wild-caught sea cucumbers in simple sea pens, or dedicated sublittoral areas, to the size above sexual maturity that optimises earnings.

TL;DR: The biology of the fish stocks of the major species in the Bahir Dar Gulf of Lake Tana, the largest lake in Ethiopia, has been studied based on data collected during August 1990 to September 1993.
Abstract: The biology of the fish stocks of the major species in the Bahir Dar Gulf of Lake Tana, the largest lake in Ethiopia, has been studied based on data collected during August 1990 to September 1993. The distribution, reproduction patterns, growth and mortality dynamics and gillnet selectivity of these stocks are described. The major fish categories, Barbus spp., Clarias gariepinus, and Oreochromis niloticus contribute equally to the catches. O. niloticus is most abundant in the shallow littoral zone, while C. gariepinus and the larger piscivorous Barbus species are found mainly in the deeper open water area of the lake. These larger species are mainly exploited by the motorized boat fishery. The catch from the reed boat fishery, confined to the littoral zone, consists mainly of O. niloticus and Barbus tsanensis. The breeding activity of all major species is associated with the rainy period and increase in lake water level. C. gariepinus has a short breeding period in July whereas O. niloticus and B. tsanensis show extended activity with peak breeding during July and September-October respectively. They are fully recruited to the fishery at 2 - 4 years of age well beyond the age of maturity. During the breeding period a higher catch rate is observed for Barbus species. The sustainable potential yield of 32 kg.ha. -1.yr. -1estimated for the Bahir Dar Gulf area, indicates that there is scope for some expansion of the fishery. The shortage in fish storage, distribution and marketing facilities, the limited local market and lack of fishing tradition are major constraints to the development of the fishery.
