This book was released on 1980 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents the results of research on herring in the eastern Bering Sea from March 1978 through September 1979. Although capelin were originally included, the research on those fish stocks along with some data gathering objectives were dropped due to funding constraints. Research objectives include describing and monitoring separate spawning stocks of herring, evaluating their distribution, abundance, and spawning success, and evaluating abundance survey methods. Aerial surveys covered coastal waters from Port Moller to Bering Strait. Shore based studies were carried out at Metervik Bay, Tongue Point, Security Cove, Goodnews Bay, Nelson Island, Cape Romanzof, Cape Denbigh and Grantley Harbor.

This book was released on 2016 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This document was part of the information presented at a regional peer review of the assessment framework for the fall spawning component of Atlantic herring in the southern Gulf of St. Lawrence (sGSL) (NAFO Div. 4T). The stock area for the sGSL Atlantic herring extends from the north shore of the Gaspe Peninsula (Quebec) to the northern tip of Cape Breton Island (Nova Scotia) and includes the Magdalen Islands. The two seasonal herring spawning components that are assessed for the sGSL are spring spawners and fall spawners. SGSL herring are harvested by an inshore gillnet fleet fishing in coastal waters and a purse seine fleet of a maximum of 12 seiners (>65') fishing in deeper water. Since 1999, fall spawners have comprised 70% or more of the total catch in the sGSL. Market conditions have played a large role in determining catch levels in this fishery. There are approximately 3,000 herring bait licenses for personal use in the sGSL. In 2012 and 2013, there was an average of 712 actively fishing gillnet commercial licenses out of a possible total of 2,590 license holders. The assessment for each herring component currently provides a F0.1 fishing level calculation. Gillnet catch-per-unit-effort (CPUE) and acoustic survey indices were used to calibrate the population models. Spawning stock biomass reference points consistent with the Precautionary Approach were derived for both spawning components in 2005. The latest assessment of the sGSL herring stocks in 2013 showed pathological problems including blocks of residuals and large retrospective patterns when fitting the current population model. Similar problems were encountered in past assessments of the sGSL herring stocks"--Abstract.

This book was released on 2004 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document presents an analytical assessment of the spring spawning stock of Atlantic herring (Clupea harengus harengus) on the west coast of Newfoundland using Sequential Population Analysis. A second objective was to determine the acceptable catch levels in 2004 assuming various exploitation rates and changes in the spawning biomass of this stock.
