Effects of Barotrauma on Four Species of Pacific Rockfishes (<i>Sebastes Spp.</i>)
… fish, such as Pacific rockfishes (genus <em>Sebastes</em>), have closed swim bladders that help them regulate their buoyancy. When anglers catch these fish and reel them to the surface, gases within their swim bladder expand due to the decrease in pressure. This can cause their swim bladder …

Diversification of beaked redfish, Sebastes mentella, along a depth gradient in the central North Atlantic
… and speciation. The pelagic beaked redfish, Sebastes mentella, exhibits depthassociatedpatterns of population genetic substructure in the central North Atlantic, with awidely distributed population inhabiting waters between 200 and 550m depth and localisedputative populations dwelling at …

Spatial and Temporal Comparisons of Gopher Rockfish (Sebastes carnatus) Life History and Condition in South Central California
… management strategies. Gopher rockfish,<em> Sebastes carnatus</em>, comprise 50% of the estimated shallow nearshore recreational rockfish catch in California, yet insufficient local data exist regarding life history traits and condition of this species. Our study locally defines growth …

Spatial and ecological patterns of mercury and arsenic concentrations in Pacific Ocean Perch (Sebastes alutus) from British Columbia
Pacific ocean perch (Sebastes alutus) is a slow growing species of demersal rockfish, which inhabits the continental slope of the west coast of North America. This species represents a highly commercial fishery and an important part of the groundfish fishery of British Columbia. A variety of …

Spatial and Temporal Variation in Growth Rate of Blue Rockfish (Sebastes mystinus) in Nearshore Central California Determined Using a Physiological Biomarker
… variation in growth of Blue Rockfish (<em>Sebastes mystinus</em>) along nearshore central California, USA. Blue Rockfish were sampled between 2016 and 2018 from two different regions ~60 km apart on the central coast of California: the Piedras Blancas region and the Point Buchon region. In …

The Insulin-Like Growth Factor-1 (IGF1) System as a Potential Biomarker for Nutritional Status and Growth Rate in Pacific Rockfish (SEBASTES SPP.)
… of somatic growth in olive rockfish (<em>Sebastes serranoides</em>), one species among dozens of rockfishes important to commercial and recreational fisheries in the Northern Pacific Ocean. I reared juvenile olive rockfish under food ration treatments of 1% or 4% wet mass per d for 98 d to …

Evaluating eelgrass (Zostera marina) as a juvenile habitat for rockfishes : contributions of site characteristics and larval supply to juvenile abundance
… beds in Barkley Sound by juvenile rockfishes (Sebastes spp.) was investigated. Rockfish have been observed in Z. marina beds by many researchers, however, their abundance and distribution between beds has been shown to be variable. The abundance of juvenile rockfishes in five beds was assessed …

Real-Time PCR Combined with DNA Barcoding for the Authentication of Red Snapper (Lutjanus campechanus) Fillets
… <em>Rhomboplites aurorubens</em>), rockfish (<em>Sebastes</em> <em>flavidus </em>and <em>Sebastes brevispinis</em>), sea bream (<em>Pagrus</em> <em>major/Pagrus auratus</em>), and mahi-mahi (<em>Coryphaena hippurus</em>). The real-time PCR assay tested in this study can serve as a rapid screening …

Determining the Usefulness of Aerobic and Anaerobic Enzyme Assays as Proxies for Rockfish Ecological Data.
… This study examined 19 different species of Sebastes from the Southern California Bight over four seasons (late summer, fall, winter, and spring) using metabolic enzyme assays. Enzymes used were lactate dehydrogenase (LDH), malate dehydrogenase (MDH), pyruvate kinase (PK), and citrate …

Movement of Selected Nearshore Temperate Reef Fishes Along California's Central Coast
… temperate nearshore fish species, especially the Sebastes genus (rockfishes). Movement behavior of temperate reef-fishes plays an important role in the level of protection that a reserve will afford a species. Consistent small-scale movements (<10 km) and limited home range sizes decrease the …

The Response of a Predatory Fish, Ophiodon elongatus, to a Marine Protected Area: Variation in Diet, Catch Rates, and Size Composition
… some of its prey species, such as rockfish (<em>Sebastes</em> spp.), are species that are protected from fishing in some California MPAs. Lingcod is an apex predator that consumes a variety of fish and invertebrate species. In this study, I sought to assess the effect of an MPA on the abundance, …
