Book excerpt: "Landings from the American plaice fishery in the Gulf of St. Lawrence have been stable since 1963. A series of commercial catch and effort data from 1972-1980 is presented using a median smoother. The commercial CPUE however, may not be indicative of trends in the overall fishery since the large vessels of the mobile fleet do not direct their effort on plaice. Data from research vessel surveys indicate that a number of strong year-classes, especially those of 1971 and 1972 are entering the fishery. Biomass estimates for 1980 also indicate that the total plaice biomass has doubled since 1970"--Abstract.

[...] Modal lengths were at 29 cm during the early portion of the survey (1971 to 1990) and began declining during the early 1990s to attain 24 cm in the early 2000s and decreased further to 22 cm in the past five years. [...] Similar to the sGSL index, the biomass of Yellowtail

Available in PDF, EPUB and Kindle. Book excerpt: Over the past several years, many investigators interested in the effects of man-made sounds on animals have come to realize that there is much to gain from studying the broader literature on hearing sound and the effects of sound as well as data from the effects on humans. It has also become clear that knowledge of the effects of sound on one group of animals (e.g., birds or frogs) can guide studies on other groups (e.g., marine mammals or fishes) and that a review of all such studies together would be very useful to get a better understanding of the general principles and underlying cochlear and cognitive mechanisms that explain damage, disturbance, and deterrence across taxa. The purpose of this volume, then, is to provide a comprehensive review of the effects of man-made sounds on animals, with the goal of fulfilling two major needs. First, it was thought to be important to bring together data on sound and bioacoustics that have implications across all taxa (including humans) so that such information is generally available to the community of scholars interested in the effects of sound. This is done in Chaps. 2-5. Second, in Chaps. 6-10, the volume brings together what is known about the effects of sound on diverse vertebrate taxa so that investigators with interests in specific groups can learn from the data and experimental approaches from other species. Put another way, having an overview of the similarities and discrepancies among various animal groups and insight into the “how and why” will benefit the overall conceptual understanding, applications in society, and all future research.
