Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.

Having survived Borneo, Amazonia, and the Congo, the indefatigable Redmond O’Hanlon sets off on his next adventure: his own perfect storm, in the wild waters off the northern tip of Scotland. Equipped with a fancy Nikon, an excessive supply of socks, and no seamanship whatsoever, O’Hanlon joins the commercial fishing crew of the Norlantean, a deep-sea trawler, to stock a bottomless hull with their catch, even as a hurricane roars around them. Rich in oceanography, marine biology, and uproarious humor, Trawler is Redmond O’Hanlon at his finest.

Sedimentary coasts with their unique forms of life and productive ecosystems are one of the most threatened parts of the biosphere. This volume analyzes and compares ecological structures and processes at sandy beaches, tidal mudflats and in shallow coastal waters all around the world. Analyses of local processes are paired with comparisons between distant shores, across latitudinal gradients or between separate biogeographic provinces. Emphasis is given to suspension feeders in coastal mud and sand, to biogenic stabilizations and disturbances in coastal sediments, to seagrass beds and faunal assemblages across latitudes and oceans, to recovery dynamics in benthic communities, shorebird predation, and to experimental approaches to the biota of sedimentary shores.

Genetics and Fish Breeding gives an intensive survey of this vital subject, featuring species which are reproduced economically, for example, salmon, trout, carp and goldfish. The writer, has drawn together an abundance of data, giving a book which ought to be purchased by all fish researcher, fisheries researchers, geneticists and aquarists. A training initially created to deliver quality seed in imprisonment, actuated rearing has made awesome walks in angle populaces for India. The book offers a functional and concise diagram-from existing methods and operations to late patterns and their effects on aquaculture for what's to come. Provides point by point data about observational rearing practices like blended bringing forth and aimless hybridization; Presents the environmental and hormonal impact on development and bringing forth of fish with genuine fish rearing cases from around the globe; Includes well ordered logical measures to help tackle issues emerging from regular fish-cultivating botches; Provides genuine cases to maximize fish and seed creation to help general maintainability in aquaculture.

The Palk Bay region, which separates the coastal regions of Tamil Nadu from northern parts of Sri Lanka, has been in the headlines during recent years. The rich fishing waters, especially lucrative on the Sri Lanka side of the maritime boundary, became a bone of contention between Tamil Nadu fishermen and the Sri Lanka Navy during the years of the ethnic conflict. With the declaration of a ceasefire between the Sri Lanka Government and the the Tamil Tigers, a new dimension has been added to the problem. Sri Lankan fishermen have resumed fishing operations; however, they find poaching by Indian trawlers into Sri Lanka waters to be a major hindrance to their livelihood. The irony of fisheries in the Palk Strait is that while the trawling ground is limited, trawlers are unlimited. As more and more fishermen start fishing for less and less, storm clouds gather over the Palk Bay. What is the background to this controversy? What are the major issues? Can Indian interests, especially the interests of Tamil Nadu fishermen, be ensured, fostered and protected without depriving the livelihood of Sri Lankan fishermen? Can India and Sri Lanka work together and jointly enrich the marine resources in the southern part of South Asia? This book is an attempt to throw light on these and other relevant critical issues. It is hoped the conclusions would stimulate fresh thinking in New Delhi, Colombo, Chennai and Jaffna. REVIEWS
