The authors estimate that between 17.9 and 39.5 million tons (average 27.0 million) of fish are discarded each year in commercial fisheries. These estimates are based on a review of over 800 papers. The highest quantities of discards are from the Northwest Pacific while tropical shrimp trawl fisheries generate a higher proportion of discards than any other fishery type, accounting for one third of the global total. Of four major gear groups, shrimp trawls stand alone at the top of the list; bottom trawls, long-lines and pot fisheries come next. The third group consists of Japanese high-seas drift net fisheries, Danish seines and purse seines for capelin. Relatively low levels result from pelagic trawls, small pelagic purse seines and some of high seas drift nets. The authors point to inadequate data to determine the biological, ecological, economic and cultural impacts of discards although economic losses run to billions of dollars. However, it appears most likely that socio-cultural attitudes towards marine resources will guide international discard policies. Techniques to reduce bycatch levels including traditional net selectivity, fishing gear development and time/area restrictions, are discussed. Effort reduction, incentive programmes and individual transferable quotas (that make the vessel responsible for bycatch reduction) are seen as promising avenues for the future. However, quick solutions to the problem are unlikely and much more information is required. The publication includes a diskette with the complete Bycatch Database, which was compiled for the study, and a summary of it.

This book describes the 1873 voyage of the British explorer Benjamin Leigh Smith, based on the diaries and photographs of Lieutenant Herbert C. Chermside, who joined the expedition of the seas around Svalbard. Chermside’s photographs, long believed lost, have recently been uncovered in Sweden and are being curated there by the Grenna Museum. The three unpublished diaries of Herbert Chermside were lent to the Scott Polar Research Institute in 1939 by Mrs. Benjamin Leigh Smith. For the first time, Chermside’s diaries are published in their entirety, with the original photographs shown alongside modern images of the same locations. This includes the first photographic record of the north coast of Svalbard, images that are today being used as comparative data for the study of climate change in the archipelago. The diaries have been fully transcribed and edited. Introductory chapters are included, written by specialists in the history of exploration, history of science, and the history of photography from Penn State University, the University of Gothenburg, and UiT, the Arctic University of Norway, as well as contributors from the UK and Germany. This volume is published in association with Grenna Museum, which will present Chermside’s photographs in a 2022 exhibit on Leigh Smith and A.E. Nordenskiold.

This assessment is a summary of the accumulated scientific understanding of the estuary and Gulf of St. Lawrence. It discusses the extent of anthropogenic modifications to this marine environment, points out principal uncertainties that hinder our understanding, and identifies important regional environmental issues. Many assessments attempt to provide easy-to-understand information to a wide, non-specialist audience. Others are directed more specifically to scientists, but include a conclusions section written for non-scientists. This document offers something of a middle approach: it is intended to be understood by a non-specialist audience, albeit one with a general knowledge of contemporary science. At the same time, it gives the professional scientist a broad-scale synthesis of current information.

Aristotle's zoological writings with their wealth of detailed investigations on diverse species of animals have fascinated medieval and Renaissance culture. This volume explores how these texts have been read in various traditions (Arabic, Hebrew, Latin), and how they have been incorporated in different genres (in philosophical and scientific treatises, in florilegia and encyclopedias, in theological symbolism, in moral allegories, and in manuscript illustrations). This multidisciplinary and multilinguistic approach highlights substantial aspects of Aristotle's animals.
