“…While large egg size may compensate for low relative fecundity by increasing survival (Bagenal 1969, Wallace & Aasjord 1984, it may be that under conditions of poor growth large eggs are necessary to 'provide a better start in life' (Beattie 1987) and the corresponding reduction in relative fecundity is itself compensatory. Marsh (1984Marsh ( , 1986 suggests that large eggs of the orangethroat darter, Etheostoma spectabile, are advantageous where food is scarce. Similarly, Koskela & Pasenan (1975) found fewer and larger eggs in the common frog, Rana temporaria, from northerly latitudes and higher altitudes, where the growing season is short.…”

SynopsisEight geographically-diverse (33" 11' N to 39" 14' N) populations of least brook lamprey varied significantly in density of larvae and mean length of metamorphosing and adult lampreys (101-152 mm). Absolute fecundity (503-5900 eggs) did not change significantly with stage of post-larval development, suggesting little post-metamorphic atresia; egg dry weight increased to stage 6, the penultimate stage of metamorphosis. Absolute fecundity increased with the cubic power of total length. Relative fecundity (250-1124 eggs per gram total body weight) decreased significantly with increasing length within two streams. Relative fecundity, adjusted to a common length, increased with mean length of the population. Conversely, mean egg dry weight (0.09-0.24 mg, stages 6-8) increased with maternal length within three streams, and decreased with length among streams. In populations where spawning occurs at a small body size, females produce comparatively fewer but larger eggs. Large eggs may be required to counter the effects of an unproductive environment and the accompanying reduction in relative fecundity is compensatory. No relationship was evident between latitude, annual thermal units, or density and relative fecundity or egg size. Mean length of a population was also unrelated to these environmental factors.

“…In multiple-spawning fish egg size may initially increase with successive spawnings to a maximum value and later decrease. The latter pattern was observed for egg diameter in Amur loach (Misgurnus anguillicaudatus) (Suzuki, 1983) and egg dry weight in the orange throat darter (Etheostoma spectabile) (Marsh, 1984). Tinca tinca egg dry weight and energy content (J egg )1 ) tended to be largest in the middle of the breeding season and smaller early and late in the season, but this result was not significant (Kamler and Stachowiak, 1992).…”

“…In multiple spawning fishes, a tendency for egg size to decrease between successive clutches laid by the same individual has been frequently observed (Marsh, 1984;Hinckley, 1990;McEvoy & McEvoy, 1991;Kjesbu et al, 1996). McEvoy & McEvoy (1991) observed this pattern in turbot Scophthalmus maximus (L.) even when environmental conditions were constant.…”

Among individuals of female three-spined sticklebacks Gasterosteus aculeatus from a population in the Camargue, southern France, studied in 12 successive years, adult L T ranged from 31-64 mm, clutch size ranged from 33-660 eggs, and mean egg diameter per clutch ranged from 1·15-1·67 mm. Because the population was strictly annual, inter-annual variation corresponded to variation among generations having experienced different environmental conditions. Body mass varied significantly among years, suggesting an effect of varying environmental conditions. Gonad mass and clutch size increased with body mass, but mean egg diameter was not correlated to body mass. Body mass-adjusted gonad mass, interpreted as reproductive effort per clutch, did not vary significantly among years, suggesting that this trait was not influenced by environmental conditions. Body mass-adjusted clutch size and egg size varied significantly among years. Inter-annual variation in body length at breeding, clutch size and egg size was of the same order of magnitude as inter-population variation reported by other authors for this species. During the breeding season, reproductive effort and clutch size tended to increase. Egg size tended to decrease during the breeding season but this seasonal pattern varied among years. Observed life-history variation is discussed both in terms of its evolutionary significance and methodological implications in the study of life-history variation among populations.
