Effects of ration on the maturation and fecundity in captive Atlantic herring (<i>Clupea harengus</i>)

Abstract: Abstract:We examined the effects of amount of food on vitellogenic oocyte size and number (fecundity) between two experimental groups of Atlantic herring (Clupea harengus) kept in separate but identical compartments of a large seawater tank. Growth and maturation were monitored for 1.5 years. Each group of 200 fish was fed exclusively on krill. At the end of the experiment, a high-ration group, fed 12 mg⋅g fish -1 ⋅day -1 , had similar weights-at-length as wild specimens of the same stock. A low-ration group f… Show more

“…Factors such as nutritional condition or ration level have been found to be positively related to fecundity (Kjesbu et al, 1991;Millner et al, 1991;Rijnsdorp, Year 199219951996199719981999 Number of eggs ('000) at 40 cm 1991; Rijnsdorp et al, 1991;Kjesbu et al,1998;Ma et al, 1998;Lambert and Dutil, 2000). Selective pressures from fisheries have also been suggested as a factor in changes in fecundity with fishing mortality selecting for fish that have a higher investment in reproduction earlier in life, including increased fecundity (Yoneda and Wright, 2004;Wright, MS 2005).…”

“…However, there is evidence that the probability of spawning omission at a given level of condition may be affected by diet composition Rideout and Rose, 2006). In addition, fish may resorb only some oocytes, rather than totally skipping spawning (Hislop et al, 1978;Ma et al, 1998;Thorsen et al, 2006).…”

“…Numerous studies showed relations between potential fecundity and many environmental factors such as food abundance/ availability/ consumption, temperature, fish density, and biomass index (Trippel, 1998;Lambert et al, 2003;Kamler, 2005). Laboratory studies demonstrated the positive relation between potential fecundity and food ration in haddock (Melanogrammus aeglefinus), plaice, herring and winter flounder (Pseudopleuronectes americanus) (Tyler and Dunn, 1976;Hislop et al, 1978;Horwood et al, 1989;Ma et al, 1998). In natural environment, prey abundance/density has been related to potential fecundity in cod (Kjesbu et al, 1998;Marshall et al, 1999;Kraus et al, 2002) and to batch fecundity in the anchovy (Encrasicolina heteroloba) (Milton et al, 1995).…”
