By Andrew I. L. Payne, John Cotter, Ted Potter

This well timed booklet brings readers brand new at the wide variety of advances made in fisheries technology because the booklet in 1957 of at the Dynamics of Exploited Fish Populations (Beverton and Holt), looked by means of many fisheries scientists as probably the most very important books on fisheries but published.

Traditional fishery topics lined contain old declines and adjustments in fishing fleets, fisheries administration and inventory checks, data-poor events, simulation and modelling of fished shares, fisheries economics, assessing reproductive power and dispersal of larvae, fisheries for sharks and rays, and use of marine know-how. also, similar topics of accelerating value now that ecological methods to administration are coming to the fore are offered. They contain benthic ecology, environment alterations associated with fishing, lifestyles heritage thought, the results of chemical substances on fish copy, and use of sounds within the sea by way of marine existence. numerous chapters provide stimulating philosophical dialogue of the various debatable components nonetheless existing.

This major e-book, edited by way of Andy Payne, John Cotter and Ted Potter and containing contributions by way of world-renowned fisheries scientists, together with many established at Cefas (where Beverton and Holt's unique paintings used to be conducted) is an important buy for fisheries managers and scientists, fish biologists, marine scientists and ecologists. Libraries in all universities and learn institutions the place fisheries and organic sciences are studied and taught are inclined to want copies of this landmark publication.

Example text

9 Several fisheries scientists, including Beverton and Holt (1957a) and Gulland (1956) working simultaneously in Lowestoft, compared the fishing power of steam and motor trawlers in the North Sea. Beverton and Holt (1957a) reported that in the southern North Sea during the years 1946 and 1947, fishing power calculated from total demersal cpue was approximately proportional to gross tonnage in both steam and motor trawlers. 4. 32 times as powerful (again in terms of the cpue of total demersal fish).

However accurate this statement may be, it is clear that Brixham fishers used light beam trawls in the western English Channel well before the French Revolution. The fishery began to expand during the Napoleonic wars, apparently benefiting from 2 provisioning problems associated with high fish prices (Robinson, 2000a). When Anglo–French hostilities ended in 1815, Brixham trawlermen gradually began to explore fishing grounds farther east in the Channel, and settled in fishing towns close to these new grounds.

By 1898, otter trawls were adopted on virtually all steam trawlers. Garstang (1900) concluded that the resulting total fishing power of a single steam trawler by 1898 had become equivalent to eight smack units, or twice that of the 1884 steam-propelled beam trawler. ERA 2 – FIRST HALF OF THE 20TH CENTURY: DOMINATION OF STEAM TRAWLING Around the turn of the 20th century, steam trawlers were being built rapidly in Great Britain, and by 1900 their combined number in English and Scottish east coast ports was no less than 1 251, according to official statistics.
