Résumé :	The increasing demand of world population for protein food such as that derived from the seas has led to improved technology for specialized fish catching methods. This in turn has led to heavy and often over-fishing with the threat of elimination of some species. Inevitably this must invoke conservation measures. In light of these developments the author, an outstanding gear designer and net maker, foresees the need for the development of working/catching units with a high degree of proficiency and flexibility. He advances the view that to cope more efficiently with depleting stocks, specific gears should be more generally adopted. By careful concentration on shoals of mature fish (e.g herring), indiscriminate catching of immature fish could be avoided and damage by mass hauls reduced. Appreciation of this need led to the production of this book which is intended to encourage the more efficient design and handling of gears fitted for the capture of pelagic and semi-pelagic fish. Many of the successful developments in current use have contributed to the commercially sound specifications already in use and outlined in this book.

Résumé :

The increasing demand of world population for protein food such as that derived from the seas has led to improved technology for specialized fish catching methods.

He advances the view that to cope more efficiently with depleting stocks, specific gears should be more generally adopted. By careful concentration on shoals of mature fish (e.g herring), indiscriminate catching of immature fish could be avoided and damage by mass hauls reduced.
