SummaryCatchability is a concept in fishery biology which reflects the efficiency of a particular fishery. Its quantitative magnitude is expressed by the catchability coefficient, which relates the biomass abundance to the capture or fishing mortality. This paper is a comprehensive review of catchability including the development of our knowledge, interpretation and estimation.Catchability patterns indicate that the catchability coefficient has been used in two main lines: (a) increased… 

Annual trends in catchability and fish stock assessments

A key assumption of many fish stock assessment models is that catchability is constant over time. We assume here that trends in catchability may occur through fishing power creeping. The tuning

This study quantify the effects of 11 variables on the catchability and fishing power of pelagic longlines, which are used to catch tunas and billfishes in the open ocean and highlights significant problems in deriving indices of abundance from commercial catch and effort data.

Improving the definition of fishing effort for important European fleets by accounting for the skipper effect

The scope of this paper is to quantify, for a wide selection of European fisheries, fishing tactics and strategies and to evaluate the benefits of adjusting the definition of. fishing effort using

Preliminary Estimates of Historical Variations in the Fishing Power and Catchability of Pelagic Longline Fishing Gear

I quantify the effects of 11 variables on the catchability of pelagic longlines, which are used to catch tunas and billfishes in the open ocean. Extension of the depth range and the duration of

Bioeconomic assessment of a change in fishing gear selectivity: the case of a single-species fleet affected by the landing obligation

A bioeconomic simulation of a change in the gear selectivity from 100- to 120-mm minimum mesh size was performed, showing that the private perspective (profits) does not change and this gain could be re-distributed to provide an incentive for selectivity improvements.

Area-based management and fishing efficiency

What makes fish vulnerable to capture by hooks? A conceptual framework and a review of key determinants

Considerable time and money are expended in the pursuit of catching fish with hooks (e.g., handlining, angling, longlining, trolling, drumlining) across the recreational, commercial and subsistence



On the dynamics of exploited fish populations

Series foreword A.J. Pitcher. Foreword D. Pauly. Part One: Fundamentals of the theory of fishing, illustrated by analysis of a trawl factoy. Introduction:- theoretical methods in the study of fishery


The California Pacific sardine fishery is examined for the period 1932 to 1950 to determine if the catchability coefficient, based on available measures of fishing effort, varied as a function of

Quantitative fisheries stock assessment: Choice, dynamics and uncertainty

I Introduction.- 1 Role of Stock Assessment in Fisheries Management.- 2 Objectives of Fisheries Management.- II Behavior of Fisheries.- 3 Behavior of Exploited Populations.- 4 The Dynamics of Fishing


The role of artificial reefs as a tool for increasing fishery production rather than just aggregating fish is addressed for two fisheries, octopus, Octopus dofeini, and flatfish, (Pleuronectidae),

Use of catchability equations for population estimation of marron, Cherax tenuimanus (Smith) (Decapoda : Parastacidae)

Compared with other methods of estimation in which equal catchability is assumed, this method takes into consideration variation in catchability, requires no marking of individuals, and needs only one sampling occasion to obtain an estimate of crayfish numbers.

A stochastic catch-effort method for estimating animal abundance.

A method for estimating the size of a heavily exploited animal population from catch data and relative-harvest-effort data is presented and a 68% reduction in the mean sum of squares for error is obtained and the accuracy of future catch predictions is greatly improved.

Using Frequency Distributions of Catch per Unit Effort to Measure Fish‐Stock Abundance

Abstract Mean catch per unit effort often is used as an index of fish abundance, N. This index is often biased. Frequency distributions of catch per unit effort (C/f) and independent estimates of N

Size Selection of Snappers (Lutjanidae) by Hook and Line Gear

To determine which type of curve best describes the selective sampling characteristics of fish hooks, an experiment was conducted in the Marianas Islands during 1982-84 and showed that neither model in its simplest form depicted hook selectivity well.

Aspects of the population dynamics of the western rock lobster, Panulirus cygnus George. II. Seasonal changes in the catchability coefficient

The catchability coefficient of a population of the western rock lobster P. cygnus was calculated monthly from November 1969 to January 1973 and was positively correlated with water temperature and water salinity, and negatively correlated with the percentage of rock lobsters in a premoult condition.
