“…In the life cycle experiments, these could be calculated from the lengths and fecundities of the first three or four adult instars. An increasing fecundity with increase in body size of female has been reported by many workers (see review by Ivanova et al, 1987) and the regressions plotted in Fig. 2 for five species of Cladocera show very steep slopes in optimal non-limiting food concentrations.…”

This review considers what is known about the effects of food limitation upon the life cycle characteristics of rotifers and planktonic cladocerans. The characteristics considered in rotifers are the size of eggs, juveniles and adults and the durations of the juvenile phase and period of egg production. In cladocerans, the life history features dealt with are their length-weight relationships, the body size, instar stage, age and fecundity of the primiparous female and their fecundity-adult size relationship. The influence of limiting food conditions is demonstrated for these characteristics by comparison with the situation in non-limiting circumstances; the comparison is confined to experiments where food concentrations are quantified. A direct comparison is made between rotifers and cladocerans in conditions of defined food resource availability in terms of their length-weight relationships, the daily allocation of adults or near-adults to growth and reproduction and their threshold food concentrations. These comparisons are discussed in relation to the following topics: the high cost of cumulated respiration resulting from prolongation of the juvenile phase of body growth; the fundamentally different nature of growth in the two taxonomic groups; the body size of species and the size that must be attained for reproduction; the ecological implications of the very different threshold food concentrations.

“…Clutch size in E. latreillii increased sharply with maternal size, corroborating similar findings regarding both spider crabs from the northern hemisphere and brachyuran crab species from other families (Hines, 1982(Hines, , 1991Ivanova and Vassilenko, 1987). Our results thus provide further support for the hypothesis that female body size is the principal determinant of fecundity in brachyuran crabs (Hines, 1982).…”

Egg production in <i>Eurypodius latreillei</i> Guérin, 1828 (Decapoda: Majidae) in the Strait of Magellan, southern Chile

et al. 1999

SUMMARY: Egg production and reproductive investment were studied in the spider crab Eurypodius latreillii from the Straits of Magellan, southern Chile. A total of 66 ovigerous females were analyzed, ranging in size from 29.0 to 62.9 mm carapace length. E. latreillii produced up to 15886 embryos, and clutch size increased with maternal size. Initial egg size was large (0.162 mm 3 ), and the embryo volume increase during the incubation period was 32 %. Brood mortality was substantial (83 %), and since egg volume increase could not compensate for the egg loss, average egg mass volume decreased considerably during embryogenesis. The average brood mass at laying accounted for 13 % of the maternal body mass (on a wet mass basis), and this value coincides with previous findings concerning energy allocation for egg production in other brachyuran crabs. In general, our data regarding E. latreillii correspond well with those from spider crab species inhabiting the northern hemisphere. The large egg size of E. latreillii compared with majids from other geographical regions may be an indication of a latitudinal gradient in the reproductive biology of majid crabs. Future studies with spider crabs from the southern hemisphere are desirable to substantiate this assumption.Key words: egg production; energy allocation; brood mortality; southern hemisphere, Majidae. GUÉRIN, 1828 (DECAPODA: MAJIDAE) EN EL ESTRECHO DE MAGALLANES, SUR DE CHILE. -Se estudió la producción de huevos y la inversión reproductiva del cangrejo araña Eurypodius latreillii proveniente del Estrecho de Magallanes, sur de Chile. Se analizaron un total de 66 hembras ovígeras con un rango de tamaños entre 29,0 y 62,9 mm de longitud de caparazón. E. latreillii produjo hasta un máximo de 15886 embriones, y el número de huevos aumentó con el tamaño de la hembra. El tamaño inicial del huevo fue grande (0,162 mm 3 ) y el aumento del volumen embrionario durante el período de incubación fue de 32 %. La mortalidad de huevos fue considerable (83 %), y como el aumento en el volumen de los huevos no pudo compensar la pérdida de huevos, el promedio del volumen de la masa de los huevos disminuyó de forma considerable durante la embriogénesis. La masa de huevos representó un 13 % de la masa corporal de la madre, y este valor coincide con observaciones previas sobre la asignación de energía para la producción de huevos en otros braquiuros. En general, nuestros datos sobre E. latreillii concuerdan con datos sobre especies del cangrejo araña del hemisferio norte. El tamaño grande de huevos de E. latreillii comparado con Majidae de otras regiones geográficas podría ser interpretado como una indicación de un gradiente latitudinal en la biología reproductiva de cangrejos májidos. Para corroborar esta interpretación se requerirían estudios futuros con cangrejos araña del hemisferio sur.

Parameters of equations relating wet and dry body weight to length have been calculated for four species of caprellids from the Japan Sea (Possjet Bay), specifically Caprella cristibrachium, C. kroyeri, C. penantis, and C. bispinosa. A common equation was obtained for oxygen consumption rate in relation to body weight. It was shown that within the Order Amphipoda the metabolic rate of caprellids is 1.5 times lower than that of gammarids. The differences in the fecundity of gravid females of four species and females of one species in the spring and summer, respectively, are shown. At the same time the relationship between number of eggs per female and wet body weight of female is approximated by one equation. The equation obtained shows that caprellids represent an ecologically homogeneous group.
