Intraspecific variability in reproductive patterns in the temperate hermaphrodite fish, Labrus bergylta

Marine and Freshwater Research (2013)

David Villegas‐Ríos Alexandre Alonso‐Fernández Rosario Domínguez‐Petit Fran Saborido‐Rey

For many fish populations reproductive patterns remain unknown, which often results in inadequate management strategies. Timing and intraspecific variability in the main reproductive traits of ballan wrasse (Labrus bergylta) were investigated based on microscopic analysis of gonads sampled from NW Spain in 2009–2012. This species displays two main body colour patterns, plain and spotted, which coexist in sympatry. Females spawned from January to April whereas spawning capable males were present almost year-round. Length at 50% maturity did not differ between colour patterns and was above the minimum catch size. Plain individuals attained the length and age at 50% sex change earlier than spotted individuals, which might be explained by differences in growth patterns, mortality rates or by an evolutionary genetic divergence between populations. Individuals with gonads infected by encysted trematode metacercariae were associated with an earlier timing of sex change, which represents one of the few examples of a possible parasitic influence on the sex allocation of its host. Our findings provide a framework for scientific-based management of this hermaphrodite fish.

Study of the relationship between total egg production, female spawning stock biomass, and recruitment of Flemish Cap cod (Gadus morhua)

Ciencias Marinas (2010)

Alfonso Pérez‐Rodríguez M. J. Morgan RM Rideout Rosario Domínguez‐Petit Fran Saborido‐Rey

In stock-recruitment relationships, spawning stock biomass (SSB) has traditionally been assumed to be equivalent to total egg production (TEP); however, in the last decade a number of studies have indicated the need to include more biological complexity in measures of reproductive potential and advocate the use of TEP instead of SSB. The relationship between fecundity and length is often used to estimate TEP. In that case, the equations used to estimate female spawning stock biomass (FSSB) and TEP only differ in the coefficients determining the fecundity and weight relationships with length. In the present paper, TEP and FSSB have been estimated for Flemish Cap cod (Gadus morhua) for the period from 1978 to 2008. Total egg production was calculated using six different fecundity-length relationships applied to the whole time series in each case. A greater difference between the allometric coefficient in the weight-length and fecundity-length relationships led to a lower correlation between FSSB and TEP. The TEP time series using higher fecundity allometric coefficients explained a greater proportion of recruitment variance. Despite this pattern, correlation between FSSB and TEP was always higher than 0.96. These results support the necessity of making annual estimates of potential fecundity and studying its relation not only to length but to other variables, such as fish condition, in order to really get an improvement of TEP over FSSB as a predictive variable in recruitment assessments.

Parental Effects and Reproductive Potential of Fish and Marine Invertebrates: Cross-Generational Impact of Environmental Experiences

Fishes (2022)

Rosario Domínguez‐Petit Cristina García‐Fernández Ezequiel Leonarduzzi Karina A. Rodrígues Gustavo J. Macchi

The reproductive success of aquatic animals depends on a complex web of relationships between the environment, the attributes of the reproductive individuals and human-induced selection. All of them are manifested directly or indirectly through parental effects, which can also compensate for certain external impacts. Parental effects refer to the influence that the phenotype and environmental conditions in which individuals develop exert on the phenotype of their offspring, and they can even have transgenerational impact. This paper describes the different types of parental effects and reviews the published literature to analyze the causes of their variation and their impact on reproductive resilience and population dynamics.

Reproductive strategy, egg characteristics and embryonic development of Greenland halibut (Reinhardtius hippoglossoides)

ICES Journal of Marine Science (2012)

Abstract Domínguez-Petit, R., Ouellet, P., and Lambert, Y. 2013. Reproductive strategy, egg characteristics and embryonic development of Greenland halibut (Reinhardtius hippoglossoides). – ICES Journal of Marine Science, 70: 342–351. Despite the commercial importance of Greenland halibut (GH), important gaps exist in our knowledge of the reproductive and early life stage biology for this species. The present study examined through laboratory experiments the spawning strategy, realized fecundity, egg characteristics, biochemical composition, and embryonic development of GH. The results confirmed the hypothesis that GH is a single-batch spawner producing large eggs, resulting in low realized fecundity. Embryonic development and hatching time are highly dependent on incubation temperature; 50% hatching occurred after 46, 30, and 24 days at 2, 4, and 6°C, respectively. Few changes in the biochemical composition of the eggs are observed during embryonic development. Newly hatched larvae are not well developed, having a large yolk sac, no pigmentation and incomplete development of the jaws. Egg specific density confirmed the mesopelagic distribution of the eggs at sea. However, important buoyancy changes occurring in the last 3–4 days before hatching indicate that larvae hatch higher in the water column. These results are important for understanding advection and dispersion processes of GH eggs and larvae and the connectivity between spawning grounds and nursery areas.
