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.

  • Distribution, Abundance, and Diversity of Epifaunal Benthic Organisms in Alitak and Ugak Bays, Kodiak Island, Alaska
    DISTRIBUTION, ABUNDANCE, AND DIVERSITY OF EPIFAUNAL BENTHIC ORGANISMS IN ALITAK AND UGAK BAYS, KODIAK ISLAND, ALASKA by Howard M. Feder and Stephen C. Jewett Institute of Marine Science University of Alaska Fairbanks, Alaska 99701 Final Report Outer Continental Shelf Environmental Assessment Program Research Unit 517 October 1977 279 We thank the following for assistance during this study: the crew of the MV Big Valley; Pete Jackson and James Blackburn of the Alaska Department of Fish and Game, Kodiak, for their assistance in a cooperative benthic trawl study; and University of Alaska Institute of Marine Science personnel Rosemary Hobson for assistance in data processing, Max Hoberg for shipboard assistance, and Nora Foster for taxonomic assistance. This study was funded by the Bureau of Land Management, Department of the Interior, through an interagency agreement with the National Oceanic and Atmospheric Administration, Department of Commerce, as part of the Alaska Outer Continental Shelf Environment Assessment Program (OCSEAP). SUMMARY OF OBJECTIVES, CONCLUSIONS, AND IMPLICATIONS WITH RESPECT TO OCS OIL AND GAS DEVELOPMENT Little is known about the biology of the invertebrate components of the shallow, nearshore benthos of the bays of Kodiak Island, and yet these components may be the ones most significantly affected by the impact of oil derived from offshore petroleum operations. Baseline information on species composition is essential before industrial activities take place in waters adjacent to Kodiak Island. It was the intent of this investigation to collect information on the composition, distribution, and biology of the epifaunal invertebrate components of two bays of Kodiak Island. The specific objectives of this study were: 1) A qualitative inventory of dominant benthic invertebrate epifaunal species within two study sites (Alitak and Ugak bays).

  • Echinodermata
    Echinodermata Bruce A. Miller The phylum Echinodermata is a morphologically, ecologically, and taxonomically diverse group. Within the nearshore waters of the Pacific Northwest, representatives from all five major classes are found-the Asteroidea (sea stars), Echinoidea (sea urchins, sand dollars), Holothuroidea (sea cucumbers), Ophiuroidea (brittle stars, basket stars), and Crinoidea (feather stars). Habitats of most groups range from intertidal to beyond the continental shelf; this discussion is limited to species found no deeper than the shelf break, generally less than 200 m depth and within 100 km of the coast. Reproduction and Development With some exceptions, sexes are separate in the Echinodermata and fertilization occurs externally. Intraovarian brooders such as Leptosynapta must fertilize internally. For most species reproduction occurs by free spawning; that is, males and females release gametes more or less simultaneously, and fertilization occurs in the water column. Some species employ a brooding strategy and do not have pelagic larvae. Species that brood are included in the list of species found in the coastal waters of the Pacific Northwest (Table 1) but are not included in the larval keys presented here. The larvae of echinoderms are morphologically and functionally diverse and have been the subject of numerous investigations on larval evolution (e.g., Emlet et al., 1987; Strathmann et al., 1992; Hart, 1995; McEdward and Jamies, 1996)and functional morphology (e.g., Strathmann, 1971,1974, 1975; McEdward, 1984,1986a,b; Hart and Strathmann, 1994). Larvae are generally divided into two forms defined by the source of nutrition during the larval stage. Planktotrophic larvae derive their energetic requirements from capture of particles, primarily algal cells, and in at least some forms by absorption of dissolved organic molecules.

  • Life Cycle of the Symbiotic Scaleworm Arctonoe Vittata (Polychaeta: Polynoidae)
    Ophelia Suppl. 5: 305-312 (February 1991) Life Cycle of the Symbiotic Scaleworm Arctonoe vittata (Polychaeta: Polynoidae) T A . Britayev A.N. Severtzov Institute of Animal Morphology and Ecology Lenin Avenue 33, Moscow W-71, U.S.S .R . ABSTRACT The reproductive biology, some stages of de velopment, size structure, distribution by hosts, behaviour and tr aumatism were studied in a population of Arctonoeoittata at Vostok Bay (Sea ofJapan). The species is associat­ ed with the starfish Asterias amurensis and the limpet A cmaea pallida. It is a polytelic species with an annual reproductive cycle. Spawning occu rs during June and July. Larval development is planktotrophic and lasts about a month. Distribution of young specimens is random as a result of settlement. Analysis of different size groups of sym bionts on starfish reveals a uniformity in their distribution, wh ich is increased due to the size of the pol ynoids. Intraspecific aggressive behaviour is characteri stic for thi s spe cies. Aggressive interactions among the worms stim ula te one or mor e of them to leave a host and move onto another host - mollu sc or starfish - result­ ing in a uniform distribution oflarge symbionts on the hosts . For at lea st part of the symbiont population, the starfish Astenas amurensis serv es as the intermediate host and the limpet Acmaea pallida as the definitive host. Keyword s: Polychaeta, Polynoid ae, Arctonoe, sym bionts, intraspecific aggression, distribution, reproduction. INTRODUCTION The genus ArctonoeChamberlin includes three species: the typ e speciesA. vittata (Grube), A . pulchra (johnson) and A . jragilis (Baird) (Pettibone 1953: 56-66 , pis.

  • Enteroctopus Dofleini) and That E
    THE EFFECT OF OCTOPUS PREDATION ON A SPONGE-SCALLOP ASSOCIATION Thomas J. Ewing , Kirt L. Onthank and David L. Cowles Walla Walla University Department of Biological Sciences ABSTRACT In the Puget Sound the scallop Chlamys hastata is often found with its valves encrusted with sponges. Scallops have been thought to benefit from this association by protection from sea star predation, but this idea has not been well supported by empirical evidence. Scallops have a highly effective swimming escape response and are rarely found to fall prey to sea stars in the field. Consequently, a clear benefit to the scallop to preserve the relationship is lacking. We propose that octopuses could provide the predation pressure to maintain this relationship. Two condi- tions must first be met for this hypothesis to be supported: 1) Octopuses eat a large quantity of scallops and 2) Octo- puses must be less likely to consume scallops encrusted with sponges than unencrusted scallops. We found that Chlamys hastata may comprise as much as one-third of the diet of giant Pacific octopus (Enteroctopus dofleini) and that E. dofleini is over twice as likely to choose an unencrusted scallop over an encrusted one. While scallops are a smaller portion of the diet of O. rubescens this species is five times as likely to consume scallops without sponge than those with. This provides evidence the octopuses may provide the adaptive pressure that maintains the scallop -sponge symbiosis. INTRODUCTION The two most common species of scallop in the Puget Sound and Salish Sea area of Washington State are Chlamys hastata and Chlamys rubida.
