Technical review of encircling ringed gillnet for gillnet standardization in Indonesia

IOP Conference Series: Earth and Environmental Science
Abstract A technical review of encircling ringed gill nets for gillnet standardization in Indonesia is necessary to determine the design and construction by the waters and their fish target. The aim of this study was to describe the characteristics and design of fishing gear, including dimension, shape, and construction.

Multi‐event modeling of Hector's dolphin (Cephalorhynchus hectori) fecundity using four decades of monitoring: Implications for current management of bycatch

Conservation Science and Practice, EarlyView.
Updated estimate of fecundity for Hector's dolphin is lower and more precise than prior estimation. This latest estimate suggests a lower capacity for population growth than previously thought and a reduced resilience to anthropogenic threats. Abstract Prediction of future population trajectories is vital in the management of threatened species but ...

Does nature shape risk preferences? Evidence from Chile, Norway, and Tanzania

Economic Inquiry, Volume 63, Issue 2, Page 568-590, April 2025.
Abstract Does exposure to a more risky environment affect risk preferences? Going beyond single‐case study evidence, we report results from five surveys conducted in three countries and link this with administrative data to study whether a link between exposure and preferences is detectable and widespread. We find no evidence for endogenous preferences

The Use of Gillnets for Estimation of Fish Stocks [PDF]

Journal of Animal and Veterinary Advances, 2010
In this research it has been targeted to estimate fishable stocks of Karakaya Dam Lake (in Turkey) by using fishing with gillnets method that had been suggested as an alternative method for estimating fish stocks. Productivity per hectare in the dam lake and the amount of fishable stocks has been calculated to be 13.67 kg ha-1 and 312.005 kg year-1 ...
