Book Description
The tributaries that flow into Lake Erie provide some of the best steelhead fly fishing on the planet, as well as plentiful opportunities to catch salmon, brown trout, smallmouth bass, and other species. The 400 miles of southern Lake Erie shoreline in three states—Buffalo, New York at its eastern end; Toledo, Ohio, on its western flank; and Pennsylvania’s shoreline in the middle—is affectionately called “Steelhead Alley” by the tens of thousands of anglers that come to fish it. According to many, “the Alley” is the best location within the entire Great Lakes region to catch steelhead on a fly. This book is the culmination of over twenty years of guiding and fly fishing throughout the Alley. In addition to covering steelhead in depth, it also covers opportunities for smallmouth bass, lake run brown trout, lake trout, and the occasional chinook or coho salmon that you can catch on a fly, along with the best tributaries and shorelines in which to find them. The author shares his tips for timing the best fishing, reading the water, the most productive local fly patterns, and how to rig and fish for success. He covers detailed access, individual tributary descriptions and reports, many of which are relatively unknown, plus a few new techniques that will help you put some more fish in the net.

Book Description
Techniques and theory for processing otoliths from tropical marine fish have developed only recently due to an historic misconception that these organisms could not be aged. Otoliths are the most commonly used structures from which daily, seasonal or annual records of a fish’s environmental history are inferred, and are also used as indicators of migration patterns, home range, spatial distribution, stock structure and life history events. A large proportion of projects undertaken on tropical marine organisms involve removal and processing of calcified structures such as otoliths, statoliths or vertebrae to retrieve biological, biochemical or genetic information. Current techniques and principles have evolved rapidly and are under constant modification and these differ among laboratories, and more particularly among species and within life history stages. Tropical fish otoliths: Information for assessment, management and ecology is a comprehensive description of the current status of knowledge about otoliths in the tropics. This book has contributions from leading experts in the field, encompassing a tropical perspective on daily and annual ageing in fish and invertebrates, microchemistry, interpreting otolith microstructure and using it to back-calculate life history events, and includes a treatise on the significance of validating periodicity in otoliths.

Book Description
Up-to-date information, knowledge and research in progress in scientific fields related to natural production of juvenile Atlantic salmon and some other ecologically similar fluvial salmonids is contained in the 25 papers and 12 abstracts contained in this publication, which were prepared for an international symposium held in St. John's, Newfoundland. Studies relate to stream ecology, invertebrates and predators, habitat improvement, competitive effects, behaviour and dispersal, habitat and production of juvenile salmon, population dynamics and relationships of juvenile salmon estimates to smolt yields. A list of participants at the conference is also provided.

Book Description
Stock Identification Methods, 2e, continues to provide a comprehensive review of the various disciplines used to study the population structure of fishery resources. It represents the worldwide experience and perspectives of experts on each method, assembled through a working group of the International Council for the Exploration of the Sea. The book is organized to foster interdisciplinary analyses and conclusions about stock structure, a crucial topic for fishery science and management. Technological advances have promoted the development of stock identification methods in many directions, resulting in a confusing variety of approaches. Based on central tenets of population biology and management needs, this valuable resource offers a unified framework for understanding stock structure by promoting an understanding of the relative merits and sensitivities of each approach. - Describes 18 distinct approaches to stock identification grouped into sections on life history traits, environmental signals, genetic analyses, and applied marks - Features experts' reviews of benchmark case studies, general protocols, and the strengths and weaknesses of each identification method - Reviews statistical techniques for exploring stock patterns, testing for differences among putative stocks, stock discrimination, and stock composition analysis - Focuses on the challenges of interpreting data and managing mixed-stock fisheries
