“…Larger and older marbled sole females produced larger eggs. Similar relationships between maternal attributes and egg size, larval size, or larval quality have been reported for many fishes (e.g., Buckley et al, 1991a, b;Chambers and Leggett, 1992;Chambers and Waiwood, 1996;Kjesbu et al, 1996;Solemdal, 1997;Marteinsdottir and Steinarsson, 1998;Keckeis et al, 2000;Riveiro et al, 2000;Johnston and Leggett, 2002;Fox et al, 2003;Berkeley et al, 2004;Trippel and Neil, 2004;Green and McCormick, 2005). Although we found that larger larvae had higher feeding ability, direct correlations between feeding rate and maternal attributes were not significant.…”

Maternal effects of animals are the phenotypic influences of age, size, and condition of spawners on the survival and phenotypic traits of offspring. To clarify the maternal effects for marbled sole Pseudopleuronectes yokohamae, we investigated the effects of body size, nutrient condition, and growth history of adult females on egg size, larval size, and starvation tolerance, growth, and feeding ability of offspring. The fecundity of adult females was strongly dependent on body size. Path analysis revealed that the mother's total length positively affected mean egg diameter, meaning that large females spawned large eggs. In contrast, the relative growth rate of adult females negatively affected egg diameter. Egg diameters positively affected both notochord length and yolk sac volume of the larvae at hatching. Under starvation conditions, notochord length at hatching strongly and positively affected days of survival at 14°C but not at 9°C. Under adequate food conditions (1000 rotifers L -1 ), the notochord length of larvae 5 days after hatching positively affected feeding rate, implying that large larvae have high feeding ability. In addition, the mean growth rate of larvae between 0 and 15 days increased with increasing egg diameter under homogenous food conditions, suggesting that larvae 1 hatched from large eggs might have a growth advantage for at least to 15 days after hatching. In marbled sole, these relationships (i.e., mother's body size-egg size-larval size-larval resistance to starvation-larval feeding ability) may help explain recruitment variability.

“…Future research should involve studies of the biochemical components (Buckley et al, 1991a;Keckeis et al, 2000;Riveiro et al, 2000) of marbled sole eggs and the buoyancy of larvae (Saborido-Rey et al, 2003) to estimate their quality. Table 2.…”

“…Large eggs tend to have higher caloric value than small eggs, but this is not always the case (Kamler, 2005). For Sardina pilchardus, Riveiro et al (2000) found that that time to yolk absorption was not a function of egg size but a function of egg biochemical composition (protein content) which illustrates the point we make in figure 1. We converted E 0 to V Y f with the implicit assumption that the fraction of water per volume is constant.…”

To cite this version:Starrlight Augustine, Litvak Matt, Sebastiaan Kooijman. Stochastic feeding of fish larvae and their metabolic handling of starvation. Journal of Sea Research, Elsevier, 2011, 66, pp.411-418 Developmental patterns of yolk-sac larvae are well captured by the standard deb model: (i) when feeding is delayed post birth the size at which post-feeding growth begins is reduced but the rate of growth post-feeding is unaffected and (ii) maternal effects (initial energy in egg) show up as differences in condition at birth and maximum length of non fed individuals. We extended the standard deb model in two ways to account for starvation. (I): if somatic maintenance can no longer be paid structure is also mobilized to cover the costs, but at an extra cost-conversion efficiency of structure to energy. Death occurs if structure reaches a fraction of the maximum at the onset of shrinking. (II): if maturity maintenance can no longer be paid then maturity level decays exponentially (rejuvenation). Hazard due to rejuvenation is proportional to the difference between maturity and the maximum maturity at the onset of rejuvenation.We performed Monte Carlo simulation studies which treat feeding as a random process to evaluate the contribution of the metabolic handling of starvation to early teleost life history. The simulations suggest that food density strongly impacts growth, energy reserves, mineral fluxes, hazard and mortality from shrinking. Environmental factors can soon override maternal induced differences between individuals. Moreover in the low food density, simulated individuals from eggs of lower caloric content experience mortality from shrinking earlier than their counterparts issued from higher energy eggs. Empirically observed patterns of real data, i.e. high scatter in respiration in combination with low scatter in lengths, can be expected when the metabolism is treated as a deterministic system while behaviourally controlled input is stochastic. At low food densities where mortality from shrinking reaches 10% almost all individuals experience hazard due to rejuvenation. This hazard is difficult to access experimentally but represents moments of heightened susceptibility to pathogens and toxicants and could be ecologically significant.

“…The protein, carbohydrate and lipid content of the seston fraction between 20 and 1000 µm, as described by Riveiro et al (2000), was used as an indicator of the quality of food potentially available to the larvae. In the stations in which we collected eggs or larvae for amino acid analysis, 20 m vertical net hauls (using a 20 µm mesh net equipped with a flow meter) were towed at each station.…”

We analysed the amino acid composition (AA) of eggs and larvae of the pelagic fish species Sardina pilchardus (sardine), Scomber scombrus (mackerel), Trachurus trachurus (horse mackerel) and Micromesistius poutasou (blue whiting) collected along the west Atlantic coast of Spain and from the Cantabrian Sea during March to April 2000. A discriminant analysis showed that it was possible to distinguish each fish species according to the egg and larval AA. Moreover, egg and larval AA varied among different areas within each fish species. From the data of larval abundance obtained from 5 cruises carried out along the northern Spanish coast from 1995 to 2000 (Mph-1995, Sefos-1995, Careva-1998, Jureva-1998 and Seamar-2000, the temporal and spatial overlap among fish species was estimated. There was a significant relationship between larval AA similarity and larval spatial-temporal overlap among fish species, which means that those larval species that had greater spatial and temporal overlap, had a similar larval AA. On this basis, the differences in egg and larval AA within each fish species among different areas seem to be due to differences in habitat conditions; mainly temperature, salinity, and food quality and quantity. We concluded that egg and larval AA could be used as indicators of niche resource partitioning (food resources and spatial allocation) among pelagic fish species.KEY WORDS: Fish · Egg · Larvae · Amino acid · Niche · PopulationResale or republication not permitted without written consent of the publisher
