“…Results regarding the number of hatched juveniles coincide with those previously reported in penaeid shrimps (Arcos et al 2003(Arcos et al , 2005, and in the marine crab Maja brachydactyla (Andr es et al 2010), but differ from results obtained by Islam & Yahya (2016) in the mud crab S. paramamosain. This result, along with female mortality recorded throughout the experiment, may reflect the physiological exhaustion in females of N. davidi as a consequence of multiple spawning, considering the high energetic costs associated with reproduction in species with direct development.…”

The decline with age in components of fitness is variable among different taxa and includes changes in fertility and brood quality. In this study, we selected individuals of Neocaridina davidi, a freshwater shrimp with direct development, to analyze juvenile quality and female reproductive performance over successive spawnings, both of which are correlated with female age. Given the high costs of reproduction in species with direct development, we hypothesized that female reproductive performance and juvenile quality decrease in later spawns. Two experiments were performed. In Experiment 1, we evaluated the reproductive performance of females of N. davidi and the quality of juveniles (through a food restriction test) over the first six successive spawnings. In Experiment 2, we analyzed the lipid and protein contents in juveniles from the third, fourth, and fifth spawns, after feeding them daily or starving them for 8 d or 12 d after hatching. Female mortality was observed throughout Experiment 1, along with a decrease in the proportion of ovigerous females over successive spawns. However, the interval between spawnings and the number and size of newly hatched juveniles were similar among spawns. Moreover, females that spawned many times had a reproductive efficiency similar to those that spawned few times, as evidenced by a similar percentage of broods successfully hatched and a similar percentage of broods with more than 28 juveniles among all spawns. Overall, these results may indicate a partial effect of multiple spawning on female reproductive performance. Growth, survival, and biochemical composition of food‐restricted juveniles showed similar or even higher values in later spawns as compared to the first spawns. This is, to our knowledge, the first empirical demonstration in a decapod crustacean with direct development that, although the percentage of ovigerous females decreases over time, other reproductive variables and juvenile performance do not decline in successive spawnings, at least for the initial six consecutive spawns.

“…One such phenomenon, a short latency period-often as little as three days-from unilateral eyestalk ablation to complete ovarian development and first spawn has been reported to be significantly shorter in the better spawners (Arcos et al, 2003b;Arcos et al, 2004;Bray and Lawrence, 1992;Palacios et al, 1999a). Our findings of 4.1± 3.4 days for the best-performing females vs. 6.0±4.4 Fig.…”

“…This enigmatic phenomenon and the fact that individual female performance is extremely variable has been noted in a number of studies (Table 2; Arcos et al, 2004;Arcos et al, 2003b;Arcos et al, 2003a;Bray and Lawrence, 1998;Bray et al, 1990;Hoang et al, 2003;Holtschmit and Romero, 1991;Palacios and Racotta, 2003;Palacios et al, 1999b;Palacios et al, 1999a;Racotta et al, 2003;Wyban and Sweeney, 1991). Table 2 shows that the average fraction of non-active females exceeds 30% and that, on average, less than 20% of the females contributed more than 60% of the reproductive output of the whole broodstock.…”

The major bottleneck in the breeding in captivity of penaeid shrimp is the fact that females do not spontaneously undergo vitellogenesis, which thus has to be induced endocrinologically by eyestalk ablation. Partial compensation for the low responsiveness of the females to this treatment is obtained by the use of very large broodstock populations. This old problem was newly approached in the current study by monitoring individual female life-spans and vitellogenic cycles in a small population of the Pacific white shrimp, Litopenaeus vannamei. Vitellogenic activity and spawning peaked during the second month of the four-month trial and decreased thereafter due to the sharp fall in the number of reproductively active females. Only about 75% of all the females in the broodstock were reproductively active, and most of them spawned for the first time, or exhibited fully vitellogenic ovaries, during the first two weeks post-ablation. Nevertheless, the best performing females, which comprised less than 20% of the female broodstock, matured more rapidly, exhibiting fully vitellogenic ovaries 4.1±3.4 days after eye-stalk ablation. These animals contributed more than 50% of the total eggs and nauplii produced. The total number of vitellogenic cycles recorded from all reproductively active females was 305, but in less than a third of these cycles were the females observed to be carrying spermatophores or sperm masses. Since females-but not males-in captivity undergo accelerated reproductive cycles due to the endocrine induction, it is suggested that the lack of mating consistently reported from maturation systems may be due to the lack of sufficient ready-to-mate males.

“…Surprisingly, only one other similar study of egg size variation in marine invertebrates has reported egg sizes that do not vary with brood order. In that study, the average egg size for 54 white shrimp was shown not to vary (1-way ANOVA) over 4 broods after ovoposition was artificially induced by eyestalk ablation (Arcos et al 2003). However, only 15% of the animals produced 4 broods, and those that did were shown to have had larger eggs in the first brood than those that produced fewer broods, making interpretation of the data unclear.…”

Repeatability of egg size in two marine gastropods: brood order and female size do not contribute to intraspecific variation

Egg size has been shown to vary among females in many species of marine invertebrates and fishes. Usually, however, only a single reproductive event is measured for each female, leaving open the possibility that egg size could vary significantly among broods from the same female. Here I measured egg size from 3 to 7 broods per female from 2 calyptraeid species, Crepidula atrasolea and C. ustulatulina, in 2 experiments. In a preliminary experiment, females were raised from hatching under constant temperature in incubators; in a second larger experiment, they were raised under varying temperatures on the laboratory bench top. Under both conditions, there were significant differences in egg size among broods from each female, as well as significant differences among females from the bench top. Estimates of repeatability, which give an upper boundary on the heritability of a trait, were significantly reduced when among brood variation was included in the calculations, suggesting that caution should be used in interpreting among-female components of variation in studies that measure only a single brood per female. Egg size was not related to female size, and there was an effect of brood order on egg size in only C. ustulatulina from the bench top. Eggs produced in the incubators were larger than those from the bench top and they were more variable within broods, resulting in a lower repeatability of egg size from incubator animals than from bench top animals. The significant variation in egg size at all levels of the analysis suggests that such variation should be included in models of egg size evolution, and that the evolutionary dynamics of egg size may be more complicated than reflected in current models of life-history evolution.
