Sentence examples for catchability in from inspiring English sources

We aimed to assess fish catchability in Mediterranean streams and to compare four electrofishing crews (with minor differences in gears used) and their short-term effects on fish populations.

At a minimum, the approach outlined here would protect the same proportion of fished populations as the target reduction in catches, assuming even catchability in space.

We also considered the relevance of including variables of heterogeneous catchability in the model, both from an epidemiological and a public health point of view.

There were no significant differences (p<0.01) in catchability (kg/km2), in the size composition of the catches over the course of 1 week.

The model assumes that fishing technology remains constant during each period (fishing, over-fishing, future of fishing) which is defined as catchability (q) in the model.

Catchability q in pike is density-independent (Pierce and Tomcko 2003).

Here we demonstrate how differences in catchability among vessels ("vessel effects"), as well as random variation in vessel-specific catchability over time ("vessel-year effects") can be incorporated into generalized linear mixed models through their treatment as random effects.

Identifying some the of the bio-physical variables which drive changes in fish distribution and behaviour will help quantify fish catchability and assist in the design and interpretation of better targeted surveys for top predators and prey fish species.

The overall catchability of smolts in the natural rearing environment was 428 fish in 1,300 trap hours (0.33 fish per trap hour).

These differences probably reflect changes in catchability and possibly movement of some lobsters out of the study area in response to changes in weather conditions.
