Abstract:

We assessed the value of parasites of yellowtail rockfish, Sebastes flavidus (Pisces: Teleostei), as biological tags on the Pacific coast of North America. Of the 25 parasite species found, only Microcotyle sebastis (Monogenea: Microcotylidae) showed a latitudinal cline. Prevalence of this flatworm increased from 0–10% in samples from central British Columbia, to 80 and 100% in the California and Oregon samples, respectively. Mean intensity also increased from north to south. The results indicate that stock assessments for yellowtail rockfish, which treat the coastal population as five stocks from central British Columbia to northern California, can assume that harvests in one area will have little short-term impact on distant areas.

Abstract:

A capacity for matrotrophic viviparity was established in the yellowtail rockfish Sebastes flavidus (Teleostei: Scorpaeniformes). The incorporation of radiolabel into embryos from [14C]phosphatidylcholine present in the maternal serum during gestation provided the first in vivo demonstration of matrotrophy of phospholipid for any viviparous teleost and of any nutrient for a member of the genus Sebastes. Radiolabel content increased as embryos progressed through ontogeny. Serum proteins of 170 kDa, present in vitellogenic and embryogenic females, but not in earlier stages, in immature females or in males, indicated the presence of vitellogenin in pregnant females and, thus, the potential for matrotrophic supplementation to yolk sequestered before fertilization. The retention of higher molecular mass proteins and highly phosphorylated proteins and the maintenance of total protein content in yolk during early to mid embryogenesis argue for exogenous maternal supply during gestation. As ovarian development proceeded from the oocyte through successive embryonic stages, the distribution of yolk proteins shifted from higher (6797 kDa) to lower molecular masses (<70 kDa). The results of these experimental studies corroborate data from field investigations showing that yellowtail rockfish can matrotrophically supplement embryo nutrients obtained before fertilization. Thus, yellowtail rockfish represent a teleost species positioned within the viviparity continuum and not at its extremes.

Abstract:

As with all Sebastes species, yellowtail rockfish ( S. flavidus ) produce larvae with an extended pelagic juvenile phase that can be advected in coastal currents. While dispersal potential is high, previous research on population genetic characteristics of Sebastes species indicates that apparent realized dispersal can be much lower and can exhibit complex patterns of genetic structure. We assayed 812 bp of the mitochondrial cytochrome b gene and six microsatellite loci in ∼1000 yellowtail rockfish collected from 21 sites that span the species range from southern California to southeastern Alaska. An abrupt genetic cline near Cape Mendocino, California, splits the range into a northern and southern stock, and is highly concordant between our mitochondrial (FCT = 0.32, p ≪ 0.001) and microsatellite (FCT = 0.02, p ≪ 0.001) datasets. We show that this pattern may be due to a combination of physical (oceanographic or other barriers to larval dispersal), biological (habitat differences), and historical events. This study, and both intra- and inter-specific evidence from other marine species suggests Cape Mendocino demarcates two regions experiencing divergent evolutionary trajectories, and should be considered in management strategies.

Abstract:

Abstract Identifying the role of temperature on species-specific performance is critical for predicting how species will respond to temperature increases expected under climate change. We compared the thermal performance of two sympatric Pacific rockfish species complexes (controls for relatedness and geographic location) that vary in larval life-history traits associated with different oceanographic regimes including temperature during early life-history stages: the BY complex (Black: Sebastes melanops, Yellowtail: S. flavidus) and the CQ complex (Copper: S. caurinus, Quillback: S. maliger). By using controlled experiments, we evaluated foraging activity, growth, and survival of young-of-the-year rockfish recruits under current and future habitat temperatures over a 14-day time period indicative of marine heatwave events expected with climate change. BY rockfish displayed a heat-intolerant behaviour by only foraging at temperatures within current habitat temperatures, whereas the CQ rockfish displayed a heat-tolerant behaviour by actively foraging at temperatures above current and future predicted temperatures for a limited time. Although growth and survival in each species significantly declined with temperature, the magnitude of the effect did not vary between species. Taken together, our results show that rockfish are capable of using different behavioural strategies to cope with warming and may be differentially impacted by future climate conditions.

Abstract:

Intra- and interspecifically, larger-bodied predators generally occupy higher trophic positions (TPs). With widespread declines in large predators, there is a need to understand their size-based trophic roles to predict ecosystem-level responses. In British Columbia, Canada, we examined size-based trophic interactions between predatory fishes—3 rockfish species (genus Sebastes) and lingcod Ophiodon elongatus—and their prey, converting predator δ15N signatures to TP and analyzing stomach contents. Intraspecifically, TP scaled positively with predator length and gape width, but the rates of change varied by species. Interspecifically, TP did not scale positively with the observed mean sizes or known maximum sizes of species. Lingcod TP was lower than that of yelloweye and quillback rockfishes, which were 51 and 37%, respectively, smaller than lingcod. Yellowtail rockfish had the smallest average size, yet their mean TP did not differ significantly from that of lingcod. Neither species differences in some morphometric traits known to influence body size-TP relationships nor phylogenetic history explained these results. Most prey consumed were <20% of the predator’s size, which might partially explain the lack of a size-based trophic hierarchy among species. Currently, large size classes of rockfishes are being lost due to fisheries and perhaps climate-driven changes. Our findings on intraspecific size-TP relationships indicate that fishery removals of large individuals may diminish trophic structures. Interspecific comparisons of TP suggest that, along with size, species remain an important factor in understanding trophic dynamics. In addition, smaller-bodied predator species may have significant ecological roles to be considered in ecosystem-based fisheries management.
