This study showed that reproductive successes (RPS) in fish stocks could be reproduced using only environmental factors. As the environmental factors, the monthly Arctic oscillation index and Pacific decadal oscillation were used. The RPS of 12 stock

Loop-shaped trajectories are commonly observed in the stock-recruitment relationship (SRR). A mechanism that explains why the loops emerge in SRR has been proposed, and the aim of this study was to validate this mechanism using 62 stocks that live in

Species assemblage can be fairly unstable in aquatic ecosystems because of strong environmental constraints. Measuring β diversity is one of the most useful tools for assessing community dynamics and differentiations among communities. Whereas many

I propose a mechanism that controls the stock-recruitment relationship (SRR), which should replace traditional SRR models. The difference between the traditional SRR models and the model proposed herein is whether or not a density-dependent effect is

This study developed a recruitment forecasting model based on a new concept of the stock recruitment relationship. No density-dependent effect in the relationship was assumed in the model, which showed that fluctuations in recruitment and spawning st

The aim of this paper is to discuss the validity of 20% B0, 20% Bunfished and BMSY as reference points for managing fisheries resources. I reanalyzed eight stock-recruitment relationship (SRR) sets of data that were analyzed by Myers et al. in 1994,
