“…We found a positive relationship between egg diameter and larval growth. Similar to our findings, the majority of previous studies with fish that have assessed the relationship between egg diameter and larval growth have shown the two to be positively Egg Diameter (mm) correlated (e.g., Bagenal 1969;Elliott 1984;Springate & Bromage 1985;Marsh 1986). Bluegill larvae that hatched from larger eggs were longer at hatch than those produced by smaller eggs, translating into larger, better developed larvae.…”

“…Bluegill larvae that hatched from larger eggs were longer at hatch than those produced by smaller eggs, translating into larger, better developed larvae. Egg effects may have a significant influence on the early life history of bluegill since individuals that hatch from larger eggs will outgrow the gape of predators at a younger age and are less prone to starvation (Marsh 1986;Jonas & Wahl 1998). In addition, individuals that hatch from larger eggs may begin to forage on prey items earlier and optimize growth at a younger age (Mayer & Wahl 1997;Claramunt & Wahl 2000) allowing for greater larval size.…”

Many bluegill (Lepomis macrochirus) populations are characterized by a stunted adult size structure and consist primarily of individuals that mature at a relatively young age and small size. Little is known about maternal effects in bluegill populations and whether they may explain the occurrence of stunted growth. We spawned bluegill from both stunted and non-stunted populations in experimental tanks and collected eggs and larvae from each clutch. We determined whether differences in egg and oil globule diameter and larval growth existed between eggs collected from females from each population. Egg and oil globule diameter were not related to female length and did not differ between stunted and non-stunted populations. Larvae length after 21 d was positively related to egg diameter but was not related to either female length or oil globule diameter. Consequently, egg diameter had a greater influence on larval growth than female source population or size. No differences were observed between source populations indicating that some aspects of early life history are more heavily influenced by egg properties than adult life history differences between parental source populations.

“…This suggests that maternal effect does not affect sequential growth of juveniles until the breeding season. However, large offspring generally exhibit higher survival than small offspring when food conditions are unfavorable (Mashiko 1985, Marsh 1986, Tessier & Consolatti 1989, and may be better at acquiring food resources (Knutsen & Tilseth 1985, Berejikian et al 1996, Chaparro et al 1999.…”

Some Age-0 males of the protandrous pandalid shrimp Pandalus latirostris Rathbun mature in their first year, and the proportion of these early maturing males (EMMs) in a population varies both locally and annually. Two laboratory experiments and 2 field observations were conducted to clarify the factors affecting the occurrence of EMMs. The first experiment showed that EMMs needed to grow fast until the breeding season and began producing sperm at about 14 mm carapace length. Individuals with an AMP (length of the endopod/length of the appendix masculina) value above 40 were defined as EMMs. In the second experiment, the effects of food amount, hatching date and maternal size on growth at Age-0 were examined. Food amount strongly affected the early growth. A difference in hatching date of > 2 wk caused a large difference in body size of juveniles; this difference was maintained until the breeding season 3 mo later. Large females spawned larger larvae than small females, but the size difference between larvae from large females and those from small females decreased with time. Field observations showed that at one site in Saroma Lagoon, Hokkaido, Japan, hatching occurred over a 1 mo period. In 1996/1997, we found no obvious differences of size distribution of Age-0 individuals and the occurrence of EMM as a function of location in the lagoon or year. These results may have been caused by slow growth, because water temperatures in the lagoon were much colder in 1996/1997 than during 1987 to 1995. We conclude that the occurrence of EMMs is closely related to various environmental factors in shallow waters. Therefore, the proportion of EMMs may fluctuate both locally and annually. This study shows that a small difference in juvenile growth over a short period can alter the subsequent life history of P. latirostris.

“…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.
