In the last decade, puerulus harvesting for aquaculture seed has significantly expanded in the Indo-Pacific and delivered substantial economic benefit to coastal communities. Although the puerulus fishery provides local economic benefit, there is concern that it may threaten future lobster stocks and fisheries by reducing the number of puerulus that swim to shallow waters where they can live. We explored this issue by examining: 1) whether commercial puerulus harvesting filters puerulus so that the number reaching inshore collectors, and by inference natural reef, was reduced; and 2) whether wild lobster fisheries were displaced from bays where puerulus fishing occurred. The study was conducted in two adjacent bays, one with puerulus fishing and one without. To answer the first objective, we measured catches on multiple commercial collectors within 3 kilometers of the coast and examined spatial patterns. To answer the second objective, we tracked lobster fishing activities in the locations with and without puerulus fishing. Our research was unable to find evidence of puerulus harvesting presenting a risk to wild stocks or the fisheries that depend on them (Table 1, Figure 1).
