Book The Status of the Northern Gulf of St Lawrence 3Pn 4RS Cod Stock Gadus Morhua in 2014

Download or read book The Status of the Northern Gulf of St Lawrence 3Pn 4RS Cod Stock Gadus Morhua in 2014 written by and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Assessment of the cod (Gadus morhua) stock of the Northern Gulf of St. Lawrence (3Pn, 4RS) is based on data from commercial fisheries, a tagging program, an abundance index calculated from the DFO research survey, abundance indices from the fixed gear sentinel fisheries program (longlines and gillnets), an abundance index from the mobile gear sentinel fisheries program and biological data. This document describes the data and methods used to assess several indicators including abundance, biomass, spawning biomass, natural mortality, exploitation rate and recruitment. It also includes a prediction of the stock trends until 2017. The cod stock of the northern Gulf of St. Lawrence remains in the critical zone and well below the limit reference point. The spatial distribution of this stock is now similar to that observed in the 1990s. The exploitation rate is currently low, while natural mortality is high. An annual harvest of 1,500 t for the next two seasons should allow the spawning stock biomass to increase. However, this increase is largely dependent on the abundance of the 2011 and 2012 cohorts, whose estimates will have to be clarified in the coming years.

Book Status of the Cod Stock in the Eastern Gulf of St Lawrence

Download or read book Status of the Cod Stock in the Eastern Gulf of St Lawrence written by R. Wells and published by . This book was released on 1977 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The cod of ICNAT Divisions 4RS and Subdivision 3Pn (Div. 3Pn4RS) are here considered to form one stock for management purposes. A major characteristic of this stock is a concentration off southwest Newfoundland in the winter and a movement towards the northern of the Gulf in the Spring. Cod stocks in other areas of the Northwest Atlantic have, in recent years, come under management on the basis of total allowable catches. It is the object of this paper to arrive at an estimate of the maximum sustainable yield and provide a basis for management"--Introduction.
