Our study investigates the environmental and astronomical drivers of olive ridley (Lepidochelys olivacea) hatching success at Batu Hiu Beach, Indonesia. We demonstrate that air temperature is the dominant predictor of hatching outcomes, while Earth–Moon distance exerts an additional, significant influence independent of humidity and tidal effects ...

Pacific Herring, Clupea pallasi, spawning population assessment for San Francisco Bay, 1992-93 [PDF]
We conducted hydroacoustic surveys, spawn surveys, and sampled schools and fishery landings from 8 November 1992 through 18 March 1993 to assess the status of San Francisco Bay's Pacific herring spawning population.

Rapid warming of marine environments is threatening ecosystems, especially species at the edge of their range. This study analysed the genetic structure and diversity of Australian sea lion populations and found the northernmost population to be highly isolated with extremely low genetic variation.

Discards monitoring in the Gillnet Sole Fishery
The Gillnet Sole Fishery Study Group monitored discards since 2011. This document describes results from the self-sampling. No observer trips in the Dutch Sole Gillnet Fishing have taken place under the EU data collection framework (DCF). Under the DCF The Netherlands are obliged to sample ten gill net fishing trips.

The influence of multiple stressors on the spatial distribution of corals
Abstract Coral reef ecosystems are widely threatened by global change, yet the cumulative impacts of multiple interacting stressors remain difficult to quantify over space and time. We evaluate how long‐term artisanal fishing effort, blast fishing, human population density and marine protected areas (MPAs) interact with biophysical and seascape ...

Estimation of production trend of the depik, Rasbora tawarensis (Teleostei, Cyprinidae), in Lake Laut Tawar, Indonesia [PDF]
The objective of the present study was to evaluate the production trend of the depik (Rasbora tawarensis) during the last two decades in Lake Laut Tawar. The production trend was examined based on the catch per unit efforts.

ABSTRACT The browning of freshwater ecosystems is increasingly evident in temperate and northern regions, with widespread ramifications for lake physics, chemistry, and biology. Contrasting results on how freshwater browning may impact fish have been reported, but there has been no comprehensive examination of how browning may cause cascading effects ...
