“…In the growth-mortality hypothesis (Ware, 1975;Shepherd & Cushing, 1980), it is hypothesized that predation decreases with increasing size (Folkvord & Hunter, 1986;Pepin 1991). Higher growth rates therefore enhance the chance of survival by reducing the duration of the "predation window", i.e.…”

Abstract:The Northeast Atlantic blue whiting (Micromesistius poutassou) stock has undergone striking changes in abundance in the last 15 years. The stock increased dramatically in the late 1990s due to a succession of eight unusually strong year classes and dropped again equally dramatically after 2005 when the recruitment collapsed to former levels. The North Atlantic subpolar gyre has previously been shown to have a strong influence on the behaviour of this stock: synchronous changes in the gyre and recruitment suggest a causal linkage and the possibility of forecasting recruitment. A range of mechanisms are reviewed that may explain these observed changes, with two major candidate hypotheses being identified. One hypothesis suggests that the large mackerel (Scomber scombrus) stock in this region may feed on the pre-recruits of blue whiting, with the spatial overlap between blue whiting and mackerel being regulated by the subpolar gyre. Alternatively, variations in the physical environment may have given rise to changes in the amount, type and availability of food for larvae and juveniles, impacting their growth and survival and therefore recruitment. It was not possible to draw firm conclusions about the validity of either of these hypotheses: nevertheless, forecasting recruitment to this stock may be possible in the future if the underlying mechanisms can be resolved.

The most controversial fishery in U.S. waters of the Gulf of Mexico (Gulf) is for northern red snapper Lutjanus campechanus, which collapsed in the late 1980s when stock biomass became too low to be fished commercially in the eastern Gulf. 123Rev Fish Biol Fisheries (2011) 21:187-204 DOI 10.1007 of red snapper in the Gulf, which in turn has strained the relationship between science, management, and stakeholders there. We provide a simple empirical argument and alternate interpretations of a recently published perspective on the historical fishery of red snapper in the Gulf to conclude that the preponderance of evidence used in the agency stock assessment process, and the simple arguments made here, do not support the perspective that the red snapper stock has increased in size sufficiently to defer compliance with the MSRA.

“…The Malthusian view that the development of any population must be checked by some density-dependent mechanism, and the failure to detect such mechanisms in the adult phase, have led to the hypothesis that the density-dependent regulation of marine fish numbers takes place early in life (Jones 1973, Cushing 1974, Ware 1975, Shepherd & Cushing 1980. Density-dependent competition for food is thought to reduce growth and increase the duration of the period during which the larvae are vulnerable to predators, thus leading to density-dependent mortality (Cushing 1974, Ware 1975.…”

ABSTRACT. Ontogenetic migrations of fish larvae were studied in relation to vertical distribution of their prey and their predators at a single, unstratified, 60 m deep, station off Plymouth, UK. The vertical distribution of fish larvae was highly stratified. Die1 migrations were weak. Marked ontogenetic migrations reflected a size-related shlft in the equilibrium between predation and starvation risks. Yolksac larvae concentrated in the top half of the water column where planktonic predators were the least abundant. As size increased, the overlap between the vertical distribution of the postlarvae and that of potential predators increased. Postlarval stages of species feeding on copepods were distributed in direct proportion to resource availability. This suggested an optimization of postlarval foraging behaviour in response to density-dependent competition for food. Calculations showed that the larvae themselves had little impact on their resource, but indications were found that the abundance of larval fish food was affected by other planktivorous predators. We conclude that the density-dependent competition for food suggested by the observed patterns of postlarval distribution could only be generated at the level of the entire assemblage of planktonic predators.
