Neutral conditions were short lived as a weak El Niño system developed by July and persisted throughout the remain- der of 2009. The 2009 field season saw the successful completion of the standard quarterly surveys and the Pacific sardine (Sardinops sagax) biomass survey using a total of four research vessels but also was noted for sev- eral milestones.

Our understanding of their evolutionary ecology, morphology and function has often been advanced by increasingly detailed and accurate molecular phylogenies. Here we present the next stage of multi-locus, molecular phylogenetics for the group based on analysis of 12 nuclear and mitochondrial gene sequences from 330 of the 422 damselfish species.

This family, comprising 29 genera, shows a remarkable diversity of habitat preferences, feeding, and behaviours. Twenty-four species belonging to seven genera have been reported in the Eastern Pacific region. The present study focuses on the relationship between the diet and the cephalic profile in the 24 endemic damselfishes of this region. Feeding habits were determined by means of underwater observations and the gathering of bibliographic data. Variations in cephalic profile were analyzed by means of geometric morphometrics and phylogenetic methods. The present study shows that the 24 species can be grouped into three main trophic guilds: zooplanktivores, algivores, and an intermediate group feeding on small pelagic and benthic preys. Shape variations were low within each genus except for Abudefduf. Phylogenetically adjusted regression reveals that head shape can be explained by differences in feeding habits.

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.

  • Marine Fishes of the Azores: an Annotated Checklist and Bibliography
    MARINE FISHES OF THE AZORES: AN ANNOTATED CHECKLIST AND BIBLIOGRAPHY. RICARDO SERRÃO SANTOS, FILIPE MORA PORTEIRO & JOÃO PEDRO BARREIROS SANTOS, RICARDO SERRÃO, FILIPE MORA PORTEIRO & JOÃO PEDRO BARREIROS 1997. Marine fishes of the Azores: An annotated checklist and bibliography. Arquipélago. Life and Marine Sciences Supplement 1: xxiii + 242pp. Ponta Delgada. ISSN 0873-4704. ISBN 972-9340-92-7. A list of the marine fishes of the Azores is presented. The list is based on a review of the literature combined with an examination of selected specimens available from collections of Azorean fishes deposited in museums, including the collection of fish at the Department of Oceanography and Fisheries of the University of the Azores (Horta). Personal information collected over several years is also incorporated. The geographic area considered is the Economic Exclusive Zone of the Azores. The list is organised in Classes, Orders and Families according to Nelson (1994). The scientific names are, for the most part, those used in Fishes of the North-eastern Atlantic and the Mediterranean (FNAM) (Whitehead et al. 1989), and they are organised in alphabetical order within the families. Clofnam numbers (see Hureau & Monod 1979) are included for reference. Information is given if the species is not cited for the Azores in FNAM. Whenever available, vernacular names are presented, both in Portuguese (Azorean names) and in English. Synonyms, misspellings and misidentifications found in the literature in reference to the occurrence of species in the Azores are also quoted. The 460 species listed, belong to 142 families; 12 species are cited for the first time for the Azores.

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.

Dear Ms. Changchien: Thank you for your June 6, 2018, letter requesting reinitiation of consultation with NOAA’s National Marine Fisheries Service (NMFS) pursuant to section 7 of the Endangered Species Act of 1973 (ESA) (16 U.S.C. 1531 et seq.). We also completed an essential fish habitat (EFH) consultation on the proposed action, in accordance with section 305(b)(2) of the Magnuson- Stevens Fishery Conservation and Management Act (MSA) (16 U.S.C. 1801 et seq.) and implementing regulations at 50 CFR 600. The enclosed document contains a biological opinion (opinion) that analyzes the effects of your proposal to permit the removal of one pier, ramp, float (PRF) structure and the installation of one PRF structure. In this opinion, we conclude that the proposed action is not likely to jeopardize the continued existence of Puget Sound (PS) Chinook salmon (Oncorhynchus tshawytscha), PS steelhead (O. mykiss), or PS/Georgia Basin (GB) bocaccio (Sebastes paucispinis), PS/GB yelloweye rockfish (S.

This family, comprising 29 genera, shows a remarkable diversity of habitat preferences, feeding, and behaviours. Twenty-four species belonging to seven genera have been reported in the Eastern Pacific region. The present study focuses on the relationship between the diet and the cephalic profile in the 24 endemic damselfishes of this region. Feeding habits were determined by means of underwater observations and the gathering of bibliographic data. Variations in cephalic profile were analyzed by means of geometric morphometries and phylogenetic methods. The present study shows that the 24 species can be grouped into three main trophic guilds: zooplanktivores, algivores, and an intermediate group feeding on small pelagic and benthic preys. Shape variations were low within each genus except for Abudefduf. Phylogenetically adjusted regression reveals that head shape can be explained by differences in feeding habits.
