“…The relationship between recruitment and spawning stock in fisheries has been a fundamental subject of many studies. Rejecting the null hypothesis leads to management strategies of preserving spawning stock abundance (Ricker, 1954;Beverton and Holt, 1957;Cushing, 1971;Tyler, 1992;Iles, 1994;Myers and Barrowman, 1996;Francis, 1997;Myers, 1997). In contrast, accepting the null hypothesis means, ''periods of recruitment appear to be environmentally induced and unavoidable'' (Gilbert, 1997), implying there is no need to set spawning stock threshold to keep the stock sustainable (Koslow et al, 1987;Wooster and Baily, 1989).…”

“…Both the Beverton-Holt and Ricker models assume compensatory dynamics, but they can be extended into versions that have flexible parametrization such that the models can adjust to both compensation and depensation. These model versions are the sigmoidal Beverton-Holt model [17] and the Saila-Lorda model [22,23], respectively. Both models include a shape parameter the values of which indicate depensatory dynamics when they exceed '1' (i.e.…”

The demographic Allee effect, or depensation, implies positive association between per capita population growth rate and population size at low abundances, thereby lowering growth ability of sparse populations. This can have far-reaching consequences on population recovery ability and colonization success. In the context of marine fishes, there is a widespread perception that Allee effects are rare or non-existent. However, studies that have failed to detect Allee effects in marine fishes have suffered from several fundamental methodological and data limitations. In the present study, we challenge the prevailing perception about the rarity of Allee effects by analysing nine populations of Atlantic herring (Clupea harengus), using Bayesian statistical methods. We find that populations of the same species can show either strong evidence for Allee effects or compensation. We explicitly demonstrate how the evidence for Allee effects is strongly provisional on observations made at low population abundances. We contrast our statistical approach with previous attempts to detect Allee effects and illustrate methodological issues that can lead to erroneous conclusions about the nature of population dynamics at low abundance. The present study demonstrates that there is no substantive scientific basis to support the perception that Allee effects are rare or non-existent in marine fishes.

Effects of variation in spawning stock and sea temperature on long-term temporal patterns in recruitment dynamics of 38 commercially harvested fish stocks in the northern North Atlantic were studied. Different statistical models were explored within a Ricker stock-recruitment framework. This includes, in order of complexity, adding a linear temperature term, a nonlinear (smooth) temperature effect, and non-stationarities (trends in intercept or in temperature effect) and finally allowing for a stepwise change (a threshold). The different models were compared in a uniform approach using Akaike's information criterion corrected for small sample size as the model selection criterion. The relationship between recruitment, spawning stock biomass and temperature varied over time. The most frequent alteration in the non-stationary linear models was, for 14 stocks, in the intercept in recruitment success, suggesting a change in pre-recruit mortality over time. Threshold models performed better than the best linear or nonlinear stationary models for 27 of the stocks, suggesting that abrupt changes (maybe even regime shifts) are common. For half of the stocks studied, the temperature effect was statistically significant when added to the model of the relationship between recruitment success and spawning stock biomass. This includes all 6 of the herring stocks studied, with a positive effect for cold-water stocks and negative effect for stocks in the more temperate southern areas. For the 4 plaice stocks analysed, all located towards the centre of the overall distribution range of plaice, a tendency toward recruitment being favoured by lower temperatures was found.
