Download or read book Population Characteristics of the Spiny Dogfish, Squalus Acanthias Linnaeus, 1758, from Geographically Distinct Locations in Atlantic Canada During the Summer and Fall of 1996 written by Tina Mae Moore and published by . This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A total of 1684 dogfish were sampled to determine population characteristics from three regions in Atlantic Canada: the Minas Basin, the outer Bay of Fundy, and the Gulf of St. Lawrence. The posterior dorsal spine was removed from 211 male and 475 female dogfish for ageing. Ages were determined from the spines and annuli lost to wear were calculated using a spine dimension standardized equation. This study was the first attempt to define a complete reproductive stage assessment of a shark. A total of 475 females had the reproductive tracts removed and categorized as one of six stages. The Minas Basin sample exhibited the highest number of reproductively mature females (56.1%) and female dogfish captured in the outer Bay of Fundy were predominantly immature (97.6%). Maturity for 50% of female dogfish in Atlantic Canada was calculated at 17 years of age and a total length of 83.4 cm. Male dogfish age and total length were similar between the three regions but only 11 male dogfish were taken during the entire season in the Minas Basin (male:female ratio; 1:99). The Minas Basin female dogfish were significantly larger, older, and more mature than females in the other two sampling locations. Few comprehensive studies exist on spiny dogfish in the Northwest Atlantic because it is has only recently been commercially exploited. If commercial exploitation of dogfish were to begin in Atlantic Canada it would be more economically and biologically successful as a bycatch fish with other fisheries.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The meeting was reconvened on May 29, 2014, at the Bedford Institute of Oceanography, to complete the assessment and finalize the Science Advisory Report. [...] Although the Spiny Dogfish population is considered one metapopulation, with migratory and resident components, the population model also provides regional stock abundance estimates for the Canadian and US components of the population. [...] The Canadian stock is defined as Spiny Dogfish in Canadian waters during the summer, corresponding to the timing of the Canadian DFO Summer Research Vessel (RV) survey. [...] NORTHWEST ATLANTIC SPINY DOGFISH ASSESSMENT (MAY 29, 2014) INTRODUCTION The Chair of the meeting, Tana Worcester, welcomed participants (Appendix 1B) to the conclusion of the Northwest Atlantic Spiny Dogfish framework and assessment. [...] Discussion Model Update To monitor stock status of Spiny Dogfish in Canadian waters, in the absence of US data, there was consensus during the framework meeting on January 20-21, 2014, to update the Canadian data by not including migration of Spiny Dogfish between Canada and the US (i.e., migration component turned off in model) in the 2010 population model to obtain an updated Canadian stock abun.

Download or read book Special Issue: Age and Growth of Chondrichthyan Fishes: New Methods, Techniques and Analysis written by John K. Carlson and published by Springer Science & Business Media. This book was released on 2007-04-05 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume offers a collection of papers on the quantitative assessment of age and growth in Chondrichthyan fishes. It details new hard parts for assessments of age, such as caudal thorns; new techniques like bomb radiocarbon for validation; and reexaminations of previous age and growth models. It also examines the importance of assessing the precision and accuracy of statistical formulas, analyses, and models used in age and growth studies.
