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. -

When compared 165,072 metric tons (t) of fish and invertebrates from to landings in 2012, this represents a 141% and 191% California ocean waters (fig. 1). This represents an increase in volume and value, respectively. Nearly all increase of almost 2% from the 162,290 t landed in 2012, (93.6%; 5,621.5 t) of California’s 2013 northern anchovy but still an 11% decrease from the 184,825 t landed catch was landed in the Monterey port area. Landings of in 2011, and a 35% decline from the peak landings of jack mackerel remained relatively low with 892 t landed; 252,568 t observed in 2000.

Conservation measures include artificial propagation and stocking [Povz 1996].

This species is a native species in the basin of the Black Sea (the rivers Morava and Dyje). At present, its local and time- limited occurrence depends on the stocking material from artificial culture. Conditions that will facilitate the formation of a permanent population under natural conditions are not available [Lusk et al. 2004]. […] Status of threat: extinct in the wild [Lusk et al. 2011].” From Freyhof and Kottelat (2008): “The species is severely fragmented within the Danube drainage, where most populations exclusively depend on stocking and natural reproduction is very limited due to habitat alterations and flow regime changes.” From Grabowska et al. (2010): “The exceptional case is huchen (or Danubian salmon), Hucho hucho. The huchen’s native range in Poland was restricted to two small rivers (Czarna Orawa and Czadeczka) of the Danube River basin, […]” Status in the United States Froese and Pauly (2019) report an introduction to the United States between 1870 and 1874 that did not result in an established population. -

Fishermen returning from fishing trips were interviewed at launch ramps, hoists, and boat-rental facilities. This report contains quantitative data and statistical estimates of total effort, total catch, catch of preferred species, and length frequencies for those species whose catches are regulated by minimum size limits. An estimated 356,000 organisms were landed by 134,000 anglers and 5,400 divers. The major components of the catch were Pacific mackerel, Scomber japonicus, 89,000 landed; Pacific bonito, Smda chiZiensis, 82,000 landed; white croaker, Genyonemus Zineatus, 34,000 landed; and bass, ParaZabrm spp., 33,000 landed. These species made up two-thirds of the total catch. Anglers' compliance with size-limit regulations was variable. Approximately 88% of all measured bass were legal size. -
