  • Age and Growth of Pontinus Kuhlii (Bowdich, 1825) in the Canary Islands*
    SCI. MAR., 65 (4): 259-267 SCIENTIA MARINA 2001 Age and growth of Pontinus kuhlii (Bowdich, 1825) in the Canary Islands* L.J. LÓPEZ ABELLÁN, M.T.G. SANTAMARÍA and P. CONESA Centro Oceanográfico de Canarias, Instituto Español de Oceanografía, Carretera de San Andrés, s/n, 38120 Santa Cruz de Tenerife. España. E-mail: [email protected] SUMMARY: Pontinus kuhlii is a Scorpaenidae which forms part of the bottom longline by-catch in the Canary Islands fish- eries within setting operations from 200 to 400 metres depth. Information on their biology and on the age determination and growth of the species is very scarce. The main objective of the study was to look at this biological aspect based on 421 spec- imens caught in the Canarian Archipelago during the period July 1996 and August 1997, 286 of which were male, 130 female and 5 indeterminate. Age was determined through the interpretation of annual growth rings of otoliths and scales, and the results fitted the von Bertalanffy growth function. Otolith sectionings were discarded due to annuli losses caused by the edge structure. The structures used in age interpretation showed numerous false rings that made the process difficult, causing 17% of the cases to be rejected. However, the age interpretations from scales showed less variability in relation to the whole otolith. The ages of the specimens ranged from 6 to 18 years for males and from 6 to 14 years for females. The growth parameters for males were: K= 0.132, L∞ = 46.7 and to= 1.74; for females: K= 0.094, L∞= 46.3 and to= 0.05; and for the total: K= 0.095, L∞= 52.2 and to= 1.01.

  • Status of the Chilipepper Rockfish, Sebastes Goodei, in 2007
    Status of the Chilipepper rockfish, Sebastes goodei, in 2007 John C. Field Groundfish Analysis Team Fisheries Ecology Division Southwest Fisheries Science Center 110 Shaffer Rd. Santa Cruz, CA 95060 [email protected] EXECUTIVE SUMMARY Stock Structure: This assessment applies to the chilipepper rockfish (Sebastes goodei) in the waters off of California and Oregon, in the region bounded by the U.S./Mexico border in the south through the Columbia River in the north. Although the distribution is described in the literature as ranging from Queen Charlotte Sound (British Columbia) to Bahia Magdalena (Baja California Sur), the region of greatest abundance is found between Point Conception and Cape Mendocino, California. Catch History: Chilipepper rockfish have been one of the most important commercial target species in California waters since the 1880s, as well as an important recreational target in Southern California waters historically, and an important recreational target in central and northern California more recently (following the movement of recreational fishing effort to deeper waters in the 1970s and 1980s). Catches were estimated to have begun in 1892, and are estimated to have ranged from several hundred to nearly 1000 tons throughout the first half of the 20th century. Gear types are grouped into four general categories; trawl, hook and line, setnet, and recreational; since World War II a majority has been taken with trawl gear, although hook and line, setnet, and recreational gear have accounted for between 20 and 40% of landings for most of the last three decades. As early rockfish landings were only reported at the genus level, a combination of historical data and publications, as well as anecdotal accounts of early line, trawl, and recreational fisheries, were used to reconstruct the fraction of catch by gear and sector assumed to be chilipepper.

  • 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.

WESTERN ATLANTIC SCORPIONFISHES By ISAAC GINSBURG U. S. Fish and Wildlife Service INTRODUCTION The present state of the taxonomy of the western Atlantic scor- paenids leaves much to be desired. The literature is filled with inade- quate original or supplementary descriptions of species, containing many unessential details of little or no practical use for the correct determination of the species, while the critical characters that dis- tinguish the species often are not considered adequately. I found it well-nigh impossible to identify and distinguish the species properly by the use of current accounts. One of the main factors that operate to bedevil the taxonomist who conscientiously tries to identify his specimens is the undue multiplication by past authors of the number of fictitious species. Such untenable "species" have been established, in large measure, as a result of failure to elaborate properly, or even to take into consideration, the intraspecific range of variability of taxonomic characters, or their change with growth which, in the scorpaenids, is considerable. The multiplication of names that have been proposed for scorpaenid species that have no existence in fact is as confusing as the grouping of two or more closely related species under one name that has entered into the literature of other families.

ТРАНСКРИПТОМИКА УДК 577.21 THE COMPLETE MITOCHONDRIAL GENOME OF THE MARBLED ROCKFISH Sebastiscus marmoratus (Scorpaeniformes, Scorpaenidae): GENOME CHARACTERIZATION AND PHYLOGENETIC CONSIDERATIONS © 2011 TianJun Xu, YuanZhi Cheng, XueZhu Liu, Ge Shi, RiXin Wang* Key Laboratory for Marine Living Resources and Molecular Engineering, College of Marine Science, Zhejiang Ocean University, China Received April 02, 2010 Accepted for publication May 12, 2010 The complete mitochondrial genome sequence of the marbled rockfish Sebastiscus marmoratus (Scorpaeni formes, Scorpaenidae) was determined and phylogenetic analysis was conducted to elucidate the evolutionary relationship of the marbled rockfish with other Sebastinae species. This mitochondrial genome, consisting of 17301 bp, is highly similar to that of most other vertebrates, containing the same gene order and an identical number of genes or regions, including 13 proteincoding genes, two ribosomal RNAs, 22 transfer RNAs, and one putative control region. Most of the genes are encoded on the Hstrand, while the ND6 and seven tRNA genes (for Gln, Ala, Asn, Tyr, Ser (UCA), Glu, and Pro) are encoded on the Lstrand. The reading frame of two pairs of genes overlapped on the same strand (the ATPase 8 and 6 genes overlapped by ten nucleotides; ND4L and ND4 genes overlapped by seven nucleotides). The possibly nonfunctional lightstrand replication origin folded into a typical stemloop secondary structure and a conserved motif (5'GCCGG3') was found at the base of the stem within the tRNACys gene. An extent terminationassociated sequence (ETAS) and conserved sequence blocks (CSB) were identified in the control region, except for CSB1; unusual long tandem repeats were found at the 3' end of the control region.
