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.

CALIFORNIA MARINE FISH LANDINGS FOR 1972 LEO PINKAS Marine Resources Region 1.1. INTRODUCTION The protection, propagation, and wise utilization of California's living marine resources (established as common property by statute, Section 1600, Fish and Game Code) is dependent upon the welding of biological, environment- al, economic, and sociological factors. Fundamental to each of these factors, as well as the entire management pro- cess, are harvest records. The California Department of Fish and Game began gathering commercial fisheries land- ing data in 1916. Commercial fish catches were first published in 1929 for the years 1926 and 1927. This report, the 32nd in the landing series, is for the calendar year 1972. It summarizes commercial fishing activities in marine as well as fresh waters and includes the catches of the sportfishing partyboat fleet. Preliminary landing data are published annually in the circular series which also enumerates certain fishery products produced from the catch.

  • Proceedings of the Indiana Academy of Science 1 1 8(2): 143—1 86
    2009. Proceedings of the Indiana Academy of Science 1 1 8(2): 143—1 86 THE "LOST" JORDAN AND HAY FISH COLLECTION AT BUTLER UNIVERSITY Carter R. Gilbert: Florida Museum of Natural History, University of Florida, Gainesville, Florida 32611 USA ABSTRACT. A large fish collection, preserved in ethanol and assembled by Drs. David S. Jordan and Oliver P. Hay between 1875 and 1892, had been stored for over a century in the biology building at Butler University. The collection was of historical importance since it contained some of the earliest fish material ever recorded from the states of South Carolina, Georgia, Mississippi and Kansas, and also included types of many new species collected during the course of this work. In addition to material collected by Jordan and Hay, the collection also included specimens received by Butler University during the early 1880s from the Smithsonian Institution, in exchange for material (including many types) sent to that institution. Many ichthyologists had assumed that Jordan, upon his departure from Butler in 1879. had taken the collection. essentially intact, to Indiana University, where soon thereafter (in July 1883) it was destroyed by fire. The present study confirms that most of the collection was probably transferred to Indiana, but that significant parts of it remained at Butler. The most important results of this study are: a) analysis of the size and content of the existing Butler fish collection; b) discovery of four specimens of Micropterus coosae in the Saluda River collection, since the species had long been thought to have been introduced into that river; and c) the conclusion that none of Jordan's 1878 southeastern collections apparently remain and were probably taken intact to Indiana University, where they were lost in the 1883 fire.

  • Guide to the Coastal Marine Fishes of California
    STATE OF CALIFORNIA THE RESOURCES AGENCY DEPARTMENT OF FISH AND GAME FISH BULLETIN 157 GUIDE TO THE COASTAL MARINE FISHES OF CALIFORNIA by DANIEL J. MILLER and ROBERT N. LEA Marine Resources Region 1972 ABSTRACT This is a comprehensive identification guide encompassing all shallow marine fishes within California waters. Geographic range limits, maximum size, depth range, a brief color description, and some meristic counts including, if available: fin ray counts, lateral line pores, lateral line scales, gill rakers, and vertebrae are given. Body proportions and shapes are used in the keys and a state- ment concerning the rarity or commonness in California is given for each species. In all, 554 species are described. Three of these have not been re- corded or confirmed as occurring in California waters but are included since they are apt to appear. The remainder have been recorded as occurring in an area between the Mexican and Oregon borders and offshore to at least 50 miles. Five of California species as yet have not been named or described, and ichthyologists studying these new forms have given information on identification to enable inclusion here. A dichotomous key to 144 families includes an outline figure of a repre- sentative for all but two families. Keys are presented for all larger families, and diagnostic features are pointed out on most of the figures. Illustrations are presented for all but eight species. Of the 554 species, 439 are found primarily in depths less than 400 ft., 48 are meso- or bathypelagic species, and 67 are deepwater bottom dwelling forms rarely taken in less than 400 ft.

  • Localized Depletion of Three Alaska Rockfish Species Dana Hanselman NOAA Fisheries, Alaska Fisheries Science Center, Auke Bay Laboratory, Juneau, Alaska
    Biology, Assessment, and Management of North Pacific Rockfishes 493 Alaska Sea Grant College Program • AK-SG-07-01, 2007 Localized Depletion of Three Alaska Rockfish Species Dana Hanselman NOAA Fisheries, Alaska Fisheries Science Center, Auke Bay Laboratory, Juneau, Alaska Paul Spencer NOAA Fisheries, Alaska Fisheries Science Center, Resource Ecology and Fisheries Management (REFM) Division, Seattle, Washington Kalei Shotwell NOAA Fisheries, Alaska Fisheries Science Center, Auke Bay Laboratory, Juneau, Alaska Rebecca Reuter NOAA Fisheries, Alaska Fisheries Science Center, REFM Division, Seattle, Washington Abstract The distributions of some rockfish species in Alaska are clustered. Their distribution and relatively sedentary movement patterns could make localized depletion of rockfish an ecological or conservation concern. Alaska rockfish have varying and little-known genetic stock structures. Rockfish fishing seasons are short and intense and usually confined to small areas. If allowable catches are set for large management areas, the genetic, age, and size structures of the population could change if the majority of catch is harvested from small concentrated areas. In this study, we analyzed data collected by the North Pacific Observer Program from 1991 to 2004 to assess localized depletion of Pacific ocean perch (Sebastes alutus), northern rockfish S.( polyspinis), and dusky rockfish (S. variabilis). The data were divided into blocks with areas of approxi- mately 10,000 km2 and 5,000 km2 of consistent, intense fishing. We used two different block sizes to consider the size for which localized deple- tion could be detected. For each year, the Leslie depletion estimator was used to determine whether catch-per-unit-effort (CPUE) values in each 494 Hanselman et al.—Three Alaska Rockfish Species block declined as a function of cumulative catch.

We estimated energy density of 1151 ®sh from 39 species by proximate analysis of lipid, water, ash-free lean dry matter, and ash contents and evaluated factors contributing to variation in composition. Lipid content was the primary determinant of energy density, ranging from 2 to 61% dry mass and resulting in a ®ve-fold difference in energy density of individuals (2.0±10.8 kJ g21 wet mass). Energy density varied widely within and between species. Schooling pelagic ®shes had relatively high or low values, whereas nearshore demersal ®shes were intermediate. Pelagic species maturing at a smaller size had higher and more variable energy density than pelagic or nearshore species maturing larger. High-lipid ®shes had less water and more protein than low-lipid ®shes. In some forage ®shes, size, month, reproductive status, or location contributed signi®cantly to intraspeci®c variation in energy density.
