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
Download or read book Operational Plan East Cook Inlet Razor Clam Stock Assessment 2021 2023 written by Michael D. Booz and published by . This book was released on 2022 with total page 52 pages. 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.

Download or read book Razor Clams written by David Berger and published by University of Washington Press. This book was released on 2017-08-24 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this lively history and celebration of the Pacific razor clam, David Berger shares with us his love affair with the glossy, gold-colored Siliqua patula and gets into the nitty-gritty of how to dig, clean, and cook them using his favorite recipes. In the course of his investigation, Berger brings to light the long history of razor clamming as a subsistence, commercial, and recreational activity, and shows the ways it has helped shape both the identity and the psyche of the Pacific Northwest. Towing his wife along to the Long Beach razor clam festival, Berger quizzes local experts on the pressing question: tube or gun? He illuminates the science behind the perplexing rules and restrictions that seek to keep the razor clam population healthy and the biomechanics that make these delicious bivalves so challenging to catch. And he joyfully takes part in the sometimes freezing cold pursuit that nonetheless attracts tens of thousands of participants each year for an iconic “beach-to-table” experience.

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.

Book excerpt: Report of population studies of the Pacific razor clam (Siliqua patula) from the western beaches of the Kenai Peninsula (along east side of Cook Inlet), summers 1990, 1991.

This book was released on 1998 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proceedings of a symposium that focused on new, innovative evaluation of the implications and needs for changing management approaches and demands in invertebrate fishery science. Species covered in the presentations include crustaceans, gastropods, echinoderms, and bivalves. Presentations are organized in the following subject areas: assessment of abundance and related parameters; growth, mortality, and yield per recruit; spatial pattern and its implications; the fishing process; population dynamics; the fishery as a selective force; invertebrate fisheries management; and regional perspectives from the north Pacific. The proceedings conclude with a symposium overview.

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.
