“…The results show that the oil droplet is not used during the first half of embryonic development. As in salmonids (Pavlov, 1989) and tropical coral-reef fish Siganus randalli (Collins and Nelson, 1993), the oil droplet in wolffish resorbs at later stages of development and remains after total resorption of the yolk sac.…”

Embryonic development of common wolffish (Anarhichas lupus L.) was studied at constant temperatures 5.0, 7.0, 9.0, 11.0, 13.0 and 15.0°C. Duration of development from egg activation to several morphological stages including 50% hatching was determined. At 5.0-11.0°C, the survival rate of eggs to hatching ranged from 51 to 88% with a tendency to increase at 5.0 and 7.0°C. Morphological anomalies, bacterial contamination and large mortalities were observed in eggs incubated at 13.0 and 15.0°C. The period of hatching lasted from 10 to 50 d in different egg groups. Embryo length and yolk sac volume at identical morphological stages of development showed only slight relation to temperature. At lower temperatures newly hatched larvae were longer and at more advanced stages of ontogeny. Normal numbers of fin rays in larvae (mean values 74 for dorsal fin and 46 for anal fin) were observed at 5.0 and 7.0°C and in most larvae at 9.0°C. At 11.0 and 13.0°C, many rays were absent, with mean values for dorsal fin 60 and 39 respectively and for anal fin 28 and 4 respectively. The approximate upper limit for normal development of fin rays appeared to be 9.0°C.

“…they spent more time fanning with increasing age of the clutch. Providing oxygen by fanning is essential for the survival and the development of the embryos (Van Iersel 1953;Bakker et al 2006a), with older clutches needing more oxygen than younger ones (Reebs et al 1984;Collins & Nelson 1993;Kamler et al 1998). Brood care was also influenced by the males' body condition (BC m2 ).…”

“…Van den Assem 1967;Belles-Isles & FitzGerald 1991;FitzGerald 1992;Frommen et al 2007;Mehlis et al 2009) and is more common late in the breeding season (Belles-Isles & FitzGerald 1991). In general, parental care is energetically costly (Smith & Wootton 1999) with more developed eggs needing more oxygen and, thus, care (Collins & Nelson 1993;Kamler et al 1998). Consequently, males lose body condition during the breeding cycle (Sargent 1985;Smith & Wootton 1999).…”

To eat or not to eat: egg-based assessment of paternity triggers fine-tuned decisions about filial cannibalism

et al. 2010

Filial cannibalism occurs in many animal species ranging from insects to mammals, and is especially well described in teleost fishes. Numerous causes may lead to this behaviour, e.g. certainty of paternity. However, the cues males use to assess their paternity often remain unknown. One possible way to differentiate between own and foreign offspring is by using egg cues. Nevertheless, in egg-laying species, evidence for this is still scarce. In this study, male three-spined sticklebacks (Gasterosteus aculeatus), a fish with paternal care in which sneaking as well as filial cannibalism is common, were allowed to care for manipulated nests that contained different percentages of own fertilized eggs. After 7 days, embryo survival was determined. Furthermore, brood-caring as well as aggressive behaviour was measured daily. Clutches containing a higher proportion of foreign eggs were more likely to be completely cannibalized than clutches containing a lower proportion of foreign eggs, particularly when the clutch was laid early in the breeding season. However, the behavioural observations revealed no influence of paternity. The results show that paternity triggers filial cannibalism in sticklebacks and that males are able to evaluate their paternity using egg cues alone.

“…Similarly, the oxygen and temperature environment into which eggs are laid may influence early developmental rates and size at hatching (e.g. Collins & Nelson 1993, Cancino et al 2003, Green 2004. As the larva exhausts its yolksac reserves and begins exogenous feeding, water temperature (Houde 1990, Houde & Zastrow 1993 and the timing of prey production cycles (Cushing 1990) become particularly important determinants of survival.…”

Maternal and paternal effects determine size, growth and performance in larvae of a tropical reef fish

Larval mortality in marine fishes is strongly linked to individual life history traits such as size and growth, but the processes that influence variability in these traits are poorly understood. We explore the relative importance of maternal and paternal influences and water temperature on the larval growth and performance characteristics of the tropical clownfish Amphiprion melanopus (Pomacentridae). Larvae were reared from an incomplete 4 male × 4 female diallel breeding cross at 2 temperatures (25 and 28°C). Paternity interacted with maternity and affected traits immediately prior to and after hatching. Size of larvae at metamorphosis was primarily affected by maternal and paternal influences, but not by rearing temperature. Paternity explained 52% of the variance in growth rates to metamorphosis, while the combination of paternity, maternity and temperature explained 30%. This strong paternal influence may be due to the extensive role males play in nesttending coupled with the relatively long embryonic duration of the species. A negative relationship between larval growth rate and mortality within a tank emphasised the importance of these parental effects to larval survival and also provides support for the 'bigger is better' hypothesis.
