Seasonal population dynamics and production of Microsetella norvegica, a widely distributed but little-studied marine planktonic harpacticoid copepod

Diet composition and food selectivity of sprat (Sprattus sprattus) in Hardangerfjord, Norway

“…This widely distributed species often represents one of the numerically dominant copepods in coastal waters in late summer and autumn, and has previously been reported as an important prey for fish larvae in temperate waters (Arthur 1976;Young & Davis 1992;Turner 2004;Morote et al 2010). There is, however, little knowledge on the basic biology of the genus (Uye et al 2002;Hjorth & Dahllö f 2008), as the traditional use of coarse-mesh samplers usually underestimates smaller copepods. It is thought to have three to four generations between March and September in boreal waters and persists during the cold period as overwintering adults throughout the water column.…”

Bacteria associated with copepods: abundance, activity and community composition

“…Copepodites were identified to species or genera, and the length of 10 individuals from each group was measured in each sample. The copepod biomass was calculated on the basis of length-carbon regressions from the literature (Berggreen et al 1988, Hay et al 1991, Hirche & Mumm 1992, Sabatini & Kiørboe 1994, Satapoomin 1999, Uye et al 2002.…”

Population structure and fecundity of the microcopepod Oncaea bispinosa in the Red Sea—a challenge to general concepts for the scaling of fecundity

“…Such values reported for Oncaea mediterranea and O. venusta range from 5 to 15 e/f/d (Sazhina 1985, Paffenhöfer 1993, Hirakawa 1995, Webber & Roff 1995. Similarly, EPR incubation data reported for nononcaeid sac-spawning microcopepods, such as species of Oithona (Paffenhöfer 1993, Uye & Sano 1995 or Microsetella (Uye et al 2002), range from 2.6 to 11.5 e/f/d. All these data extend to much higher values than even the maximum estimate obtained for the minute but abundant species O. bispinosa in the Red Sea (ca.…”
