Highlights
We investigated how local differences in maternal provisioning influenced the quality and quantity of larvae in sea perch (Helicolenus percoides, Sebastidae)
Subpopulations from Deep Cove within Fiordland, on the west coast, and the Otago shelf on the east coast of New Zealand's South Island were compared
Our results demonstrated a trade-off between fecundity and oil globule size, where sea perch from the Otago shelf were more fecund but provisioned their larvae with smaller oil globules than females from Deep Cove
The results of the present study highlight the important link between the maternal environment and the quality and fitness of fish larvae.
Ecosystem connectivity: tracking biochemical fluxes to inform EBM
We traced the fate of water and sediments from land through coastal food webs, evaluating connections between coastal and deep sea habitats, and identified the effects of key coastal developments (such as aquaculture) on food web connectivity.
