“…On a more economic ground, what could be the relative energy costs of FAD and FSC strategies? Some authors may consider that FAD fishing should result in lower fuel consumption per tonne of landed fish because of a reduced searching time (Dagorn et al, 2013;Hanich et al, 2019;Holmes et al, 2019;Parker et al, 2015).…”

“…In that respect, what could be the effects of management plans aiming at shortening FAD seasons, limiting FAD sets or the authorized number of buoys at sea? A limited number of deployed FAD buoys as well as seasonal closures represent effective ways of containing the FAD fishing capacity, rather than the closure of FAD strata or limitations in the number of FAD sets which might be more difficult to enforce (Fonteneau et al, 2015), although some authors expect some benefits from FAD set limits (Holmes et al, 2019). A 6-month moratorium on FAD sets was simulated by an iterative "fishing-day" model to look at the consequences on catch and bycatch (Escalle et al, 2017).…”

The Another attempt was made for the Pacific Ocean to look at the economic benefits of setting FAD limits instead of closure periods (Holmes et al, 2019). FAD closures were deemed ineffective because they had just the effect of increasing fishing pressure in non-closure periods/areas, except for fleets relying on FAD fishing during lower tuna price periods.…”

The management of fish aggregating devices (FAD) creates heated debates in tuna fishery management organizations striving to reduce the number of deployed floating objects. Through several econometric models and a machine learning approach, we evaluate the consequences of three management scenarios on the catch and profit of the French purse‐seine fleet operating in the Indian Ocean: (1) a half reduction in the number of authorized buoys per vessel, (2) a 72‐day closure of FAD fishing with and (3) without re‐allocation of effort on free schools. The results show a significant decrease of fleet profits by 7%, 10% and 18% respectively. We hypothesize an “economic trap” of FAD fishing caused by the far greater efficiency of this harvesting technique for larger vessels searching for economies of scale, and by the overfished status and catch limitation of yellowfin (Thunnus albacares) and bigeye (Thunnus obesus) tunas in the Indian Ocean. The results are compared with other studies looking at the impact of FAD management measures in other oceans.

“…Fish aggregating device limits other than per vessel are being discussed (Table 1). Holmes et al (2019) suggest that a limit on FAD sets could alleviate impacts on small and juvenile tuna mortality. Limiting the number of sets could also increase FAD deployments (ICCAT, 2019b) and thereby cause changes in vessel behaviour that incentivise misreporting of information (Lopez et al, 2020).…”

Drifting fish aggregating devices (dFADs) are extensively used in modern tuna purse seine fisheries. The use of dFADs has greatly improved fishing efficiency and generated substantial economic returns in purse seine fisheries, but adverse impacts on tuna juveniles, associated species and marine ecosystems are still of concern.Based on an analysis of current challenges in dFAD management measures in tuna regional fishery management organisations (t-RFMOs), we explored opportunities to strengthen dFAD management in tuna fisheries. An integrated dFAD management scheme with multiple tools that account for different usage stages of a dFAD needs to be organised to regulate, track, monitor and recover in tuna purse seine fisheries. We recommend that (1) dFAD-associated definitions should be standardised to provide operational guidance for dFAD activities; (2) all deployed dFADs should be counted towards dFAD limits on active dFADs, except those reported as lost and abandoned;(3) a regional dFAD tracking and monitoring program should track dFAD paths based on daily position reported to RFMOs directly, in addition to mandatory dFAD marking requirements; and (4) a framework of compensation mechanisms should provide financial support for joint dFAD recovery and eco-compensation.
