Sentence examples for increase catchability from inspiring English sources
Repeated use of the same areas by fish can dramatically increase catchability via reduced unit effort to find a fish, which may not be predicted by fishery models and thus could lead to higher exploitation levels [4].
The results also show that there is a large latent effort in the lobster fisheries that could threaten the sustainability of any initiatives aimed at increasing catchability, prices, or markets.
There are signs of changes in catchability [31], [50] and increased fishing pressure and effort as has been observed in the decline and collapse of other cod populations [11], [31].
Therefore, the findings of this and other studies indicate that it is worth investigating the hypothesis that the catchability of sailfish by longline increases in both hemispheres during periods of increased solar radiation, which is closely connected with the reproduction of this species.
Error in sampling location generally caused negative bias in the catchability estimates with the amount of bias increasing as location error increased.
Next we increase strengths of environmental forcing to (sigma_{1}=0.2), (sigma_{2}=0.2), and the catchability coefficient does not change.
Multi-species procedures increased precision and accuracy of parameter estimates when compared with single-species procedures, and minimized errors in annual catchability estimates when compared with the assumption of constant catchability.
This is supported by data of Namwandi (2002) indicating that during the Benguela Niño in 1995, annual catches of horse mackerel from the pelagic purse seine fishery increased 50% from 1994 to 1995, whereas catches from the mid-water fleet decreased during the same period, suggesting a higher catchability of the species in shallower waters.
"I have worked extensively on trawl fisheries, and on this very issue of catchability, and have never encountered anyone using such low catchabilities for large benthic fishes".
(ii) The catchability coefficient q is not always constant.
