Aspects of the reproductive and maturation biology of the brown shrimp Crangon crangon (L.) were studied in various subareas of the German Bight (North Sea). The size-specific sex ratio of C. crangon was examined based on length frequency distribution data. The sex ratio for the smallest size groups at which sex was determined was typically around 0.5, indicating an even ratio between males and females. The proportion of females decreased in the 30-45 mm size range. In length classes larger than 50 mm, the proportion of females constantly increases to 100% at around 60 mm total length. We concluded that sex reversal from male to female may not occur in C. crangon. Size at sexual maturity was determined from the proportion of ovigerous females. Size at maturity (L 50 ) was estimated as 55.4 and 62.0 mm total length for spring and winter data, respectively. The seasonal spawning cycle was studied over the period . Between mid February and late June and for size classes larger than 65 mm ovigerous shrimps exceeded 80% and reached up to 100% of the females in the population. This period can be seen as the core spawning season. From early August to early December the proportion of ovigerous shrimps in the female population is very low. Interannual differences in the seasonal process are obvious with a dramatic decline in C. crangon reproductive success in the late 1980s. Various options are discussed for the reasons of the decline and recovery of the reproductive performance.

“…The dominance of crustaceans in the diet of several species of Crangon has been reported, including C. crangon (Pihl & Rosenberg 1984;Oh et al 2001), C. franciscorum (Sitts & Knight 1979), and C. uritai (Hanamura & Matsuoka 2003).The diet of C. hakodatei consists of benthic organisms in three main categories: (1) organisms that, as a result of vertical migration, occur close to the benthos during part of the day (e.g. mysids, shrimps, fishes); (2) organisms that occur on or just beneath the surface of the substratum (e.g.…”

“…is the spatial and temporal availability of prey (Wilcox & Jeffries 1974;Wahle 1985;Oh et al 2001), with amphipods being the most important benthopelagic prey animals (Venables 1981;Moller & Rosenbreg 1982). Spatial differences in the diet of C. hakodatei are related to differences among habitats, particularly with respect to substrate type, which would determine the abundance and population structure of potential prey types in the community.…”

“…A number of studies have investigated the feeding behavior of crangonid shrimp including C. affinis by Kosaka (1970) and Hong and Oh (1989); C. allmani by Allen (1960); C. crangon by Lloyd and Yonge (1947); Tiews (1970), and Oh et al (2001); C. franciscorum and C. nigricauda by Wahle (1985); C. septemspinosa by Price (1962) and Wilcox and Jeffries (1974); and C. uritai by Nakaya et al (2004). However, despite its ecological and economic importance, there is no information on the diet of C. hakodatei.…”

“…They are commonly distributed on sandy, muddy, or mixed benthic substrata of littoral and sublittoral areas from cold to temperate regions of the northern hemisphere. The sand shrimp is one of the most abundant and important components of estuarine and coastal soft bottom habitats (where it is both prey and predator in the associated communities) and also has high commercial value as a protein source for human consumption (Price 1962;Tiews 1970;Boddeke 1989;Hayashi & Kim 1999;Oh et al 2001;Hanamura & Matsuoka 2003).…”

The feeding habits of the sand shrimp Crangon hakodatei in the East Sea (Korea) were investigated through analysis and comparison of the stomach contents of 602 individuals according to season, shrimp size class, and prey diversity. The diet of C. hakodatei consisted of 17 prey categories mainly comprising crustaceans, molluscs, polychaetes, nematodes, algae, and fishes, with crustaceans dominating the diet. Molluscs, nematodes, and fishes were also important prey, whilst other categories including polychaetes and algae comprised small percentages of the diet. For small C. hakodatei individuals (B10 mm carapace length [CL]), amphipods and mysids comprised more than 67% of the prey in both relative abundance and frequency of occurrence. Large individuals ( 10 mm CL) tended to be more dependent on amphipods than mysids. Amphipods and mysids together constituted the dominant prey, accounting for more than 50% of the diet in terms of both percent occurrence and relative abundance. The abundance and occurrence of prey showed a seasonal variation, with amphipods and mysids being the predominant prey in autumn (45%), winter (30%), and spring (40%). Amphipods were the dominant prey with regard to season, size class, sex, and area.
