“…The largest capture in the study area occurred in spring and the smallest in summer. Other studies (Maravelias and Reid, 1995;Power et al, 2000;Corten, 2001) stated that in certain regions, Clupeiformes were more abundant during periods of high temperatures. Nevertheless, in the internal continental shelf of Paraná State, the smallest capture values occurred in summer.…”

“…Herring migrations have typically been explained in terms of climate or predator-prey interactions (Dragesund et al 1997, Fernö et al 1998, Toresen & Østvedt 2000, Corten 2001a, Holst et al 2004. However, there is increasing support for the theory that herring migrations are influenced by social learning (Røttingen 1992, McQuinn 1997, Fernö et al 1998, Slotte 2001, Huse et al 2002, and the evidence for this has been reviewed by Corten (2001b).…”

Norwegian spring spawning (NSS) herring migrate to wintering areas in late summer and remain there for about 5 mo in dense aggregations. First-time spawning cohorts typically adopt the wintering area of the spawning stock. However, over the last 50 yr the NSS herring stock has occupied 7 discrete wintering grounds, spanning from the high seas to narrow fjords, which shows that there is considerable plasticity in choice of wintering area. We show that 5 cases of establishment of new wintering areas take place when abundant first-time spawning cohorts take up the adult migration pattern. The ratio in abundance between age 4 and age 5+ herring is on average 14 in the years when new wintering areas are established compared to 0.3 in years without changes. The wintering areas vary greatly with regards to temperature and distance to the feeding and spawning grounds, features that heavily affect energy expenditure during wintering and migration. Rather than being strictly optimized, the establishment of new wintering areas seems to be governed by general school cohesion mechanisms when naïve first-time spawners flood the population and the social learning process is disrupted.

The degree to which individuals will exert leadership is often related to their knowledge level or motivation. For example, food-deprived roach Rutilus rutilus appear more often in front of a school than wellfed individuals (Krause et al. 1992). However, it is probably costly to consistently lead a school both in terms of predation risk and energy expenditure, and in the long run individuals will have to trade off their behaviour to accommodate the rest of the school. For example, post-spawning observations of individual herring with fully developed or ripe ovaries in schools that are moving away from the spawning ground (A. Slotte pers. comm.) indicate that collective behaviours can override the strong individual urge to spawn. Thus, the school association has positive effects, e.g. related to increased foraging (Pitcher et al. 1982) and reduced mortality (Pitcher & Parrish 1993), but can also have negative effects, e.g. the tyranny of collectivity. Changes in wintering area of Norwegian spring spawning herringThe Norwegian spring spawning (NSS) herring Clupea harengus L. stock follows a classic migration pattern (Harden Jones 1968) and spends the winter in dense concentrations without feeding, awaiting and preparing for the commencement of spawning in spring and the subsequent return of plankton to the surface waters. The adult part of the stock mostly winters together in one area. There have been substantial changes in the location of the wintering area of NSS herring since the 1950s as illustrated in Fig. 1. During the 1950s and for an unknown period before, the wint...

Internal growth lines in shells of 3 suspension-feeding bivalves (Arctica islandica, Mya truncata and Chamelea striatula) from the SE North Sea were analysed in search of common interannual variations of their growth rate. The high similarity (69 to 80%) between the growth records in the 3 species suggests that a large-scale (climatic) factor is responsible for an important part of the variation in annual shell growth. The common trend extracted from the individual growth records was correlated with monthly data on phytocolour, NAO index, temperature and wind. The strength and sign of the effect of the last 3 factors varied seasonally. Effects of wind strength and direction were analysed in detail, as in situ measurements showed that wind speeds >10 m s -1 (Beaufort 6) cause resuspension of fine sediment at the site where the bivalves were collected. Resuspended sediment causes a drop in the quality of food for suspension feeders. During the bivalve growing season, northwesterly to easterly winds tended to depress growth, whereas winds with a westerly component mainly had a positive effect. Strong winds from a WNW direction in May, however, had a negative effect and could explain the highest proportion of variance in the common growth trend; WNW winds have a long fetch at the study area and generate (high) long waves, facilitating resuspension of fine sediment at relatively low wind speeds.
