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

This well timed booklet brings readers modern at the wide variety of advances made in fisheries technological know-how because the e-book in 1957 of at the Dynamics of Exploited Fish Populations (Beverton and Holt), looked through many fisheries scientists as some of the most very important books on fisheries but published.

Traditional fishery topics lined comprise old declines and alterations in fishing fleets, fisheries administration and inventory tests, data-poor occasions, 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, comparable topics of accelerating significance now that ecological techniques to administration are coming to the fore are offered. They contain benthic ecology, surroundings alterations associated with fishing, existence historical past idea, the results of chemical compounds on fish replica, and use of sounds within the sea by means of marine lifestyles. numerous chapters supply stimulating philosophical dialogue of the numerous debatable parts nonetheless existing.

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

Sample text

From about 1900 to the late 1950s, steam trawlers (Figure 2) were by far the most important component of the British fishing fleet, and in most of those years landed at least 80% of Britain’s entire North Sea demersal catch. However, there was a general decline in steam trawl effort over much of this period. Moreover, both World Wars caused significant reductions in steam trawl effort and landings, partly because vessel movements were restricted or the vessels themselves were lost in the hostilities, and partly because many vessels were requisitioned by the Royal Navy to be employed on war service, especially as minesweepers.

When stocks began to shrink). Beverton and Holt (1957a) provide a range of calculations of fishing power. Their book appeared in the period when steam trawling was gradually giving way to motor trawling (with diesel engines), and they made several comparisons of fishing power between the two. Although more refined, their methods used the same principle as Garstang’s half a century before, namely to compare the catch per unit effort (cpue) of a base vessel (base fleet) with data available over a number of years, with the cpue of other vessels (fleet or fleets) that are newly developing.

Note that these figures are only valid for the period examined – great caution is required when extrapolating any models on fishing power beyond the time-spans represented in the data (Bishop, 2006), given that fishing power may also stagnate or even decrease over time. , 2003). 15 From about the 1970s, analyses of fishing power changes can make use of the availability of several external survey indices of fish abundance in the North Sea, generally collected in a reasonably consistent way, against which commercial catch and effort data can be compared.
