Effect of food limitation during the breeding season on the size body components and egg production of female sticklebacks gasterosteus aculeatus






Journal of Animal Ecology 46(3): 823-834

Effect of food limitation during the breeding season on the size body components and egg production of female sticklebacks gasterosteus aculeatus

The effects of a reduction in food supply during the breeding season of female G. aculeatus L. were examined. The number of spawnings and total egg production were a function of ration level. Although the normal maintenance ration of a non-spawning female was estimated to be about 100 J day-1, a ration more than 5 times greater was required for the females to spawn regularly without showing a net loss in weight. At lower rations the females subsidized egg production from body tissue. Females that were spawning had relatively high levels of tissue hydration and relatively low liver weights, and in these features showed some similarities to starved females. Starved females spawned only once at the most after the onset of food deprivation. Egg production per spawning was not a function of ration level but was positively related to the weight of the female, but the interval between successive spawnings (inter-spawning interval) was negatively related to ration level. Estimates of the gross efficiency of the conversion of food into eggs indicated that this efficiency was positively related to the weight of the female, but decreased with increasing inter-spawning interval.
