Book Transboundary Management of a Fish Stock Under Climate Variability

Available in PDF, EPUB and Kindle. Book excerpt: The time variant/asymmetric distribution of a fish stock caused by ocean climate variability is one of the challenges that must be overcome to establish cooperative management of a transboundary fish stock. Pacific sardine (Sardinops sagax) exhibits extreme decadal variability in its abundance and geographic distribution that corresponds to water temperature regime shifts within the California Current Ecosystem. It is a transboundary fish stock and targeted by Mexican, American and Canadian fisheries, and the three countries do not currently have a cooperative management arrangement. This thesis explores the economic and conservation consequences of non-cooperative management, and the potential benefits of full/partial cooperative management of Pacific sardine, and studies the stability of cooperative management under ocean climate variability. The core of the thesis is presented in Chapters 2-4, with an introduction given in Chapter 1 and a conclusion in Chapter 5. Appendix A and B provide background information on Pacific sardine and the Pacific sardine fishery, respectively. Chapter 2 develops a three-agent bioeconomic framework to investigate the impact of ocean climate variability on stock abundance and geographic distribution. A game theoretic analysis was conducted to evaluate the conservation and economic benefits of various management strategies. The results show that under a regime of ocean climate variability, a country having a dominate share of the resource within its waters cannot achieve effective unilateral conservation for optimal economic benefits due to the actions of free-riders. Chapter 3 conducts simulations to evaluate the stability of full and partial cooperative management of Pacific sardine under various climate variability scenarios. The results show that in all scenarios, ocean climate variability is an obstacle to the formation of stable, fully-cooperative management of Pacific sardine fisheries as operated by the three countries.

Book Assessment of the Pacific Sardine Resource in 2016 for U S A Management in 2016 17

Download or read book Assessment of the Pacific Sardine Resource in 2016 for U S A Management in 2016 17 written by Kevin T. Hill and published by . This book was released on 2016 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Pacific sardine resource is assessed each year in support of the Pacific Fishery Management Council (PFMC) process of recommending annual harvest specifications for the U.S. fishery. The following assessment update for 2016-17 management is based on data and methods reviewed by a Stock Assessment Review (STAR) Panel during March 2014 (STAR 2014) and more fully described in Hill et al. (2014). A stock assessment update conducted in March-April 2015 served as the basis for management measures during the 2015-16 management year (Hill et al. 2015). The 2016 stock assessment update includes one additional year of data from fishery-dependent and fishery-independent sources. The draft assessment was reviewed by members of the Scientific and Statistical Committee’s CPS Subcommittee on March 10, 2016 in Sacramento, CA. The following final draft reflects minor modifications recommended during that review and was provided to the Pacific Fishery Management Council for their April 2016 briefing book"--Preface.

This book was released on 2017 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Pacific sardine resource is assessed each year in support of the Pacific Fishery Management Council (PFMC) process of stipulating annual harvest specifications for the U.S. fishery. This report serves as a full stock assessment for purposes of advising management for the 2017-18 fishing year. Presently, the assessment/management schedule for Pacific sardine is based on a full assessment conducted every three years, with an update assessment conducted in the interim years. A full stock assessment was conducted in 2014 (Hill et al. 2014; STAR 2014) and update assessments were completed in 2015 and 2016 (Hill et al. 2015, 2016)"--Preface.

Book Spawning Biomass of Pacific Sardine Sardinops Sagax Estimated from the Daily Egg Production Method Off California in 2015

Download or read book Spawning Biomass of Pacific Sardine Sardinops Sagax Estimated from the Daily Egg Production Method Off California in 2015 written by Emmanis Dorval and published by . This book was released on 2016 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Fishery independent surveys are critical for assessing and managing Pacific sardine stocks along the North American Pacific coast. These surveys provide relative abundance indices to calibrate stock assessment and to monitor stock productivity as environmental conditions change. The Daily Egg Production method (DEPM) is one of two fishery-independent surveys that are currently used to assess the northern Pacific sardine stock from Ensenada to British Columbia and to set harvest guidelines for annual management in the USA. The DEPM was developed by Lasker (1985) to estimate the spawning stock biomass of northern anchovy (Engraulis mordax) based on growth, mortality and abundance of eggs and larvae, and the adult reproductive biology of this species. The method was later applied to assess the spawning of Pacific sardine off California from 1986 to 1996 (Wolf 1988a, Wolf 1988b, Lo et al. 1996, Scannel et al. 1996, Barnes et al. 1997). Since 2004, spawning biomass computed from the DEPM has been integrated in annual stock assessments of Pacific sardine by: 1) calculating the daily egg production from ichthyoplankton survey data; 2) computing the reproductive parameters of females from adult fish samples; and 3) calculating the biomass of spawning adults"--Introduction.

Book Biology and Ecology of Sardines and Anchovies

Download or read book Biology and Ecology of Sardines and Anchovies written by Konstantinos Ganias and published by CRC Press. This book was released on 2014-03-14 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Apart from being commercially and socially significant, anchovies and sardines populations occupy crucial positions in the oceans’ ecosystems. Low in the food chain, clupeoids tend towards abundance, as if their purpose in life was to be eaten and fuel the upper levels of marine trophic chains. The present book covers a broad spectrum of topics on the biology (sytematics, phylogeography, reproduction, feeding) and ecology (habitat characterization, recruitment variability) of anchovies and sardines. It also puts together important information on the state of their fisheries, exploitation, and management.
