This book was released on 1958 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of studies beginning in 1947 on the biology of the Dungeness crab (Cancer magister) in Oregon coastal waters are reported. A review is made of the history of the fishery with regard to trend of the catch by magnitude, area, and season; the development and conduct of the fishery itself; and the regulations governing the fishery. The first reported commercial crab landings in Oregon were 6,628 pounds in 1880. The fishery expanded slowly until 1933 after which the catch rose sharply to a peak of about 11 million pounds in 1943. Landings in recent years have fluctuated between 6 and 11 million pounds from a commercial fishery which is carried out along the major portion of the Oregon coast. During the period 1947-50, 6,249 tagged crabs were released in offshore and bay waters of Oregon and 34.6 percent of the tags were subsequently recovered. The average movement of 1,042 recoveries of crabs released in offshore waters, as measured by the distance from the tagging site, was 8.3 miles (range 0-133 miles) in 80 days. For crabs released within bays, 606 recoveries averaged a minimum distance traveled of 4.2 miles (range 0-81 miles). Fifty-seven percent of the recoveries of offshore releases and 84 percent of the recoveries of bay releases were made within 4 miles of the respective tagging sites. Over 90 percent of the recoveries of offshore releases were made within 6 months, although 3 crabs were out more than a year with 1 at liberty 878 days. Tagged crabs moved from offshore to bays, from bay to bay, and from bays to offshore. There was no significant difference in percentage recovery for crabs with or without missing appendages. Egg-bearing female crabs are present in offshore waters during the period October to March, inclusive. Larval crabs assumed to be C. magister were observed in offshore waters from April to July, inclusive. Considerable variation in early growth of post larval crabs was observed in laboratory experiments. The amount of growth of crabs between 6.4 and 146.0 mm., as observed by measuring them before and after molting, increases until a shoulder width of about 95 mm. is reached. The increase with each subsequent molt thereafter remains relatively constant. Macroplankton-eating fishes feed upon free swimming crab larvae. Adult crabs up to at least 114 mm. in shoulder width are preyed upon by voracious fish such as ling-cod (Ophiodon elongatus), the great marbeled sculpin (Scorpaenichthys armoratus), wolf eel (Anarrhichthys ocellatus), halibut (Hippoglossus stenolepis), and some of the rock fishes of the genus Sebastodes.

Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive handbook of seafood information! This definitive reference is the most comprehensive handbook of information ever assembled on foods and other products from fresh and marine waters. Marine and Freshwater Products Handbook covers the acquisition, handling, biology, and the science and technology of the preservation and processing of fishery and marine products. The array of topics covered includes: aquaculture fisheries management, and harvesting o fish meal and fish oil o fish protein concentrates o seaweed products o products from shell o other industrial products o bioactive compounds o cookery o specialty products o surimi and mince o HACCP o modern processing methods o religious and cultural aspects of water products o marine toxins and seafood intolerances o contamination in shellfish growing areas o pathogens in fish and shellfish. Marketing, transportation and distribution, retailing, import and export, and a look to the future of the seafood industry are also addressed. Extensive coverage of species All major marine and freshwater finfish species are covered, as well as processing technologies: fresh fish, preserved fish, finfish processing, and other processed products. Crustaceans and other useful marine and freshwater species and their processing are also covered. These include: mollusk o clams o oysters o scallops o abalone o squid o shrimp o lobster o crawfish o crabs o eels o turtles o sea urchin o octopus o snails o alligator. The definitive seafood industry sourcebook Marine and Freshwater Products Handbook incorporates the advances in biotechnology and molecular biology, including potential drugs and medicinal products; the manufacture of chemicals from the sea; seafood safety, including toxin detection techniques and HACCP, and processing technologies. With contributions from more than 50 experts, helpful, data-filled tables and charts, numerous references and photos, this is the sourcebook for everyone involved in products from our waters. It will serve as the standard reference for the seafood industry for years to come.

Book Synopsis Reproduction and Development of Marine Invertebrates of the Northern Pacific Coast by : Megumi F. Strathmann
Download or read book Reproduction and Development of Marine Invertebrates of the Northern Pacific Coast written by Megumi F. Strathmann and published by University of Washington Press. This book was released on 2017-10-01 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference work is designed to provide background information on an array of northeastern Pacific marine invertebrate species so that they can be more easily included in comparative studies of morphology, cell biology, reproduction, embryology, larval biology, and ecology. It is meant to serve biologists who are new to the field as well as experienced investigators who may not be familiar with the invertebrate fauna of the northern Pacific Coast. The species discussed in this volume are mostly from the cold temperate waters of the San Juan Archipelago, near Puget SOund and the Strait of Georgia, but the information and methods given will be useful in laboratories from Alaska to central California and applicable to some extend in other coastal or inland facilities. An introductory chapter discusses basic prodcedures for collecting and maintaining mature specimens, for initiating spawning, and for culturing embryos and larvae in the laboratory. Subsequent chapters summarize reproduction and development in thirty different invertebrate groups and provided ercent references through which additional information can be traced, cite monographs or keys needed to identify species, and give methods useful for studying an array of selected species. Available information on habitat, diet, reproductive mode, egg size, developmental pattern, developmental times, larval type, and conditions for settlement and metamorphosis is reported for over 450 species.
