Marine Ecology Progress Series 477:177
Vol. 477: 177–188, 2013 MARINE ECOLOGY PROGRESS SERIES Published March 12 doi: 10.3354/meps10144 Mar Ecol Prog Ser Larval exposure to shared oceanography does not cause spatially correlated recruitment in kelp forest fishes Jenna M. Krug*, Mark A. Steele Department of Biology, California State University, 18111 Nordhoff St., Northridge, California 91330-8303, USA ABSTRACT: In organisms that have a life history phase whose dispersal is influenced by abiotic forcing, if individuals of different species are simultaneously exposed to the same forcing, spa- tially correlated settlement patterns may result. Such correlated recruitment patterns may affect population and community dynamics. The extent to which settlement or recruitment is spatially correlated among species, however, is not well known. We evaluated this phenomenon among 8 common kelp forest fishes at 8 large reefs spread over 30 km of the coast of Santa Catalina Island, California. In addition to testing for correlated recruitment, we also evaluated the influences of predation and habitat quality on spatial patterns of recruitment. Fish and habitat attributes were surveyed along transects 7 times during 2008. Using these repeated surveys, we also estimated the mortality rate of the prey species that settled most consistently (Oxyjulis californica) and evaluated if mortality was related to recruit density, predator density, or habitat attributes. Spatial patterns of recruitment of the 8 study species were seldom correlated. Recruitment of all species was related to one or more attributes of the habitat, with giant kelp abundance being the most widespread predictor of recruitment. Mortality of O. californica recruits was density-dependent and declined with increasing canopy cover of giant kelp, but was unrelated to predator density. -

(MONOGENEA-DICLIDOPHORIDAE),A PARASITE OF EMBIOTOCID FISHES Abstract approved: Redacted for Privacy Ivan Pratt The life cycle of a monogenean, Diclidophora sp. , was studied with special attention to the time required for developmental stages to occur.Eggs are produced by adult worms at the rate of one every 13. 5 minutes and require 32 days tohatchwhen incubated at 12. 5°C and 30.90/00salinity.Rate of development and hatching success are strongly dependent on incubation temperature and salinity. Growth and development of the larval stages are similar to other known species of the family 1T)c1idophoridae.The presence in the oncomiracidium of a precocious set of attachment clampsand the premature loss of larval hooks distinguish it from related species. Oncorniracidia survive approximately 36 hours if no host fish is reached. Larvae attach to the inner lateral borders of primary lamellae of the host fish gill.A second set of clamps is added before the 36th day, the third set soon after the 44th day, and the last pair by the 58th day.Sexual maturity is reached by the 153rd day after hatching. Experimental infections were maintained on redtail surfperch for 203 days. Naturally infected redtail surfperch, silver surfperch and walleye surfperch were collected.Rates of infection with Di clidoph- ora were 38. -
Environmental DNA Reveals the Fine-Grained and Hierarchical
www.nature.com/scientificreports OPEN Environmental DNA reveals the fne‑grained and hierarchical spatial structure of kelp forest fsh communities Thomas Lamy 1,2*, Kathleen J. Pitz 3, Francisco P. Chavez3, Christie E. Yorke1 & Robert J. Miller1 Biodiversity is changing at an accelerating rate at both local and regional scales. Beta diversity, which quantifes species turnover between these two scales, is emerging as a key driver of ecosystem function that can inform spatial conservation. Yet measuring biodiversity remains a major challenge, especially in aquatic ecosystems. Decoding environmental DNA (eDNA) left behind by organisms ofers the possibility of detecting species sans direct observation, a Rosetta Stone for biodiversity. While eDNA has proven useful to illuminate diversity in aquatic ecosystems, its utility for measuring beta diversity over spatial scales small enough to be relevant to conservation purposes is poorly known. Here we tested how eDNA performs relative to underwater visual census (UVC) to evaluate beta diversity of marine communities. We paired UVC with 12S eDNA metabarcoding and used a spatially structured hierarchical sampling design to assess key spatial metrics of fsh communities on temperate rocky reefs in southern California. eDNA provided a more‑detailed picture of the main sources of spatial variation in both taxonomic richness and community turnover, which primarily arose due to strong species fltering within and among rocky reefs. As expected, eDNA detected more taxa at the regional scale (69 vs. 38) which accumulated quickly with space and plateaued at only ~ 11 samples. Conversely, the discovery rate of new taxa was slower with no sign of saturation for UVC. -
Distribution, Abundance, and Biomass of Giant Sea Bass (Stereolepis Gigas) Off Santa Catalina Island, California, 2014-2015
Bull. Southern California Acad. Sci. 115(1), 2016, pp. 1–14 E Southern California Academy of Sciences, 2016 The Return of the King of the Kelp Forest: Distribution, Abundance, and Biomass of Giant Sea Bass (Stereolepis gigas) off Santa Catalina Island, California, 2014-2015 Parker H. House*, Brian L.F. Clark, and Larry G. Allen California State University, Northridge, Department of Biology, 18111 Nordhoff St., Northridge, CA, 91330 Abstract.—It is rare to find evidence of top predators recovering after being negatively affected by overfishing. However, recent findings suggest a nascent return of the critically endangered giant sea bass (Stereolepis gigas) to southern California. To provide the first population assessment of giant sea bass, surveys were conducted during the 2014/2015 summers off Santa Catalina Island, CA. Eight sites were surveyed on both the windward and leeward side of Santa Catalina Island every two weeks from June through August. Of the eight sites, three aggregations were identified at Goat Harbor, The V’s, and Little Harbor, CA. These three aggregation sites, the largest containing 24 individuals, contained a mean stock biomass of 19.6 kg/1000 m2 over both summers. Over the course of both summers the giant sea bass population was primarily made up of 1.2 - 1.3 m TL individuals with several small and newly mature fish observed in aggregations. Comparison to historical data for the island suggests giant sea bass are recovering, but have not reached pre-exploitation levels. The giant sea bass (Stereolepis gigas) is the largest teleost to inhabit nearshore rocky reefs and kelp forests in the northeastern Pacific (Hawk and Allen 2014). -

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences. -

Vii Fishery-At-A-Glance: California Sheephead
Fishery-at-a-Glance: California Sheephead (Sheephead) Scientific Name: Semicossyphus pulcher Range: Sheephead range from the Gulf of California to Monterey Bay, California, although they are uncommon north of Point Conception. Habitat: Both adult and juvenile Sheephead primarily reside in kelp forest and rocky reef habitats. Size (length and weight): Male Sheephead can grow up to a length of three feet (91 centimeters) and weigh over 36 pounds (16 kilograms). Life span: The oldest Sheephead ever reported was a male at 53 years. Reproduction: As protogynous hermaphrodites, all Sheephead begin life as females, and older, larger females can develop into males. They are batch spawners, releasing eggs and sperm into the water column multiple times during their spawning season from July to September. Prey: Sheephead are generalist carnivores whose diet shifts throughout their growth. Juveniles primarily consume small invertebrates like tube-dwelling polychaetes, bryozoans and brittle stars, and adults shift to consuming larger mobile invertebrates like sea urchins. Predators: Predators of adult Sheephead include Giant Sea Bass, Soupfin Sharks and California Sea Lions. Fishery: Sheephead support both a popular recreational and a commercial fishery in southern California. Area fished: Sheephead are fished primarily south of Point Conception (Santa Barbara County) in nearshore waters around the offshore islands and along the mainland shore over rocky reefs and in kelp forests. Fishing season: Recreational anglers can fish for Sheephead from March 1through December 31 onboard boats south of Point Conception and May 1 through December 31 between Pigeon Point and Point Conception. Recreational divers and shore-based anglers can fish for Sheephead year round. -
