The author's broad practical experience and proved scholastic and training ability make this the most authoritative work of its kind. Liberally illustrated, this book gives factual accounts of pareja, bull, Baltic and cod pair trawling, Canadian pair seining, freshwater and midwater pair trawling, ring net fishing, two boat purse seining, and the technique of fleet operation. With the extension of national sea limits and in modern conditions, the higher yields and greater economies of two boat fishing will become of increasing importance. Pair fishing needs less investment in vessels, manpower, fuel and yet can be more productive than large single ship operations. In this book, David Thomson clearly proveds this point by giving practical reports from operating skippers with much technical detail. An excellent glossary and bibliography complete the book which has been laid out in square format to give clear appreciation of the many illustrations and specifications.
