Modelling transport of inshore and deep-spawned chokka squid (Loligo reynaudi) paralarvae off South Africa: the potential contribution of deep spawning to recruitment

---

The South African chokka squid,Loligo reynaudi,spawns both inshore (≤70 m) and on the mid-shelf (71–130 m) of the Eastern Agulhas Bank. The fate ofthese deep-spawned hatchlings and their potentialcontribution to recruitment is as yet unknown.Lagrangian ROMS-IBM (Regional Ocean ModellingSystem-Individual-Based Model) simulations confirm westward transport of inshore and deep-spawned hatchlings, but also indicate that the potential exists for paralarvae hatched on the Eastern Agulhas Bank deep spawning grounds to be removed from the shelf ecosystem. Using a ROMS-IBM, this study determined the transport and recruitment success of deepspawned atchlings relative to inshore-hatched paralarvae. A total of 12 release sites were incorporated into the model, six inshore and six deep-spawning sites. Paralarval survival was estimated based on timely
transport to nursery grounds, adequate retention within the nursery grounds and retention on the Agul-has Bank shelf (
