Available in PDF, EPUB and Kindle. Book excerpt: This study continues long-term monitoring of Pacific razor clam (Siliqua patula) abundances, age and length compositions, growth, and the sport and personal use (SPU) fishery information on east Cook Inlet beaches. These monitoring activities are used to assess the status and productivity of the east Cook Inlet razor clam stocks to support management actions for the SPU fishery in the Ninilchik and Clam Gulch management areas. Adult razor clam abundances will be used to determine if the stock is sufficient in each management area to support harvest opportunities. Age and length compositions, growth, natural mortality, and recruitment data will all be used in indices of stock productivity for each management area. If the SPU fishery is opened in either management area, digger counts and success surveys will assess razor clam effort and harvest.

This book was released on 2014 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Alaska, the only road-accessible fishery for the Pacific razor clam, Siliqua patula, is located in eastern Cook Inlet, and has been monitored by the Alaska Department of Fish & Game (ADF&G) since 1964. In recent years, a shift has been observed in size, age, and number of clam cohorts in this region, yet little is known about the early life history of razor clams in this region. This study aimed to provide information on length and age at maturity, growth rates, and spawn timing at two beaches in eastern Cook Inlet, Ninilchik and Clam Gulch, in 2009 and 2010. At Clam Gulch, only 20% of the sampled population was reproductive, compared with 83% at Ninilchik. At Ninilchik, clams were reproductive at a smaller size and younger age (p

Book excerpt: This study continues long-term monitoring of Pacific razor clam (Siliqua patula) abundances, age and length compositions, and fishery information on east Cook Inlet beaches. Monitoring is used to assess the status of the east Cook Inlet razor clam stocks to determine management actions for the sport and personal use fishery. The 2020 adult razor clam abundances will assess whether the stock has recovered sufficiently to support harvest opportunities in 2020 at Ninilchik and Clam Gulch management areas. If the fishery opens in 2020, digger distribution and success surveys will assess effort and harvest during a limited fishery.

Book excerpt: Beaches along the east side of Cook Inlet provide the largest sport fishery for the Pacific razor clam, Siliqua patula (Dixon) in Alaska. Potential over-exploitation continues to be a concern at Ninilchik because exploitation rates peak periodically at higher levels between recruitment events. Pacific razor clam studies along 6 eastern Cook Inlet beaches will be conducted to estimate clam digger distribution, and clam harvest by beach. Harvest by age will be estimated at Cohoe, Clam Gulch, Oil Pad Access, and Ninilchik beaches. Razor clam abundance will be estimated on a section of the Ninilchik South Beach.
Download or read book Distribution and Abundance of the Pacific Razor Clam Siliqua Patula Dixon on the Eastside Cook Inlet Beaches Alaska written by Nicole J. Szarzi and published by . This book was released on 1991 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three questions were asked about the population of the Pacific razor clam Siliqua patula (Dixon) on eastside Cook Inlet beaches: (1) can density be estimated by a three-stage stratified random sampling plan; (2) can age composition data be used for age-structured population estimation; (3) does substrate composition affect clam density? Field studies of Coho, Ninilchik and Clam Gulch beaches obtained precise density estimates for Clam Gulch beach only (coefficient of variation = 14.6%, 1988, and cv = 13.6%, 1989). A heavily exploited area of high density at Clam Gulch was resampled extensively in 1989 to determine if a significant harvest rate was detectable. No significant harvest rate was detected. A catch-at-age model was successfully applied to age-structured data, and estimates of abundance for ages 4 through 11+ in years 1977 to 1989 were generated. There is some evidence from substrate analyses that clams are found in higher abundance where grain sizes 0.125 to 0.400 mm predominate.

Available in PDF, EPUB and Kindle. Book excerpt: Our current knowledge of marine organisms and the factors affecting their ecology, distribution and evolution has been revolutionised by the use, in the last 20 years, of molecular population genetics tools. This book is the result of a meeting of world-leading experts, in Rio de Janeiro, where the state of the art of this field was reviewed. Topics covered include the molecular analysis of bio-invasions, the recent developments in marine biotechnology, the factors affecting levels of genetic variation and population structure in marine organisms and their application to conservation biology, fisheries and aquaculture. This is the first book dedicated to the genetic study of marine organisms. It will be very useful to biology students, scientists and anyone working or simply interested in areas such as marine biology, zoology, ecology, and population and molecular genetics.
