“…The LBSPR model was also used to assess the spawning potential ratio of javelin grunter in the Persian Gulf and Oman Sea (Vahabnezhad et al, 2021), the overfished stock status of Atlantic Bonito in the Moroccan-Atlantic coast (Baibbat et al, 2019), and the selectivity pattern for setting length and catch limits to sustain fisheries for Bombay Duck and Hilsa Shad of the Northern Bay of Bengal Coast (Alam et al, 2021(Alam et al, , 2022. The GTG-LBSPR approach was used to assess healthy stocks of Common sole on the Iberian coast (Pennino et al, 2022) and the artisanal fishery of sea silverside in southern Chile (Mora et al, 2022). Performance of the LBSPR model provides a cost-effective starting point for management that is efficient for assessing stock status, but less so for short-lived species and to assess recruitment overfishing of severely overexploited stocks, and inconsistent for assessing growth overfishing when stocks are underexploited (Chong et al, 2020).…”

Inland capture fisheries in many parts of the world, especially in developing nations, receive relatively low governance priority, thereby raising concerns about their sustainability. Consequently, most inland capture fisheries are data‐limited, which renders conventional capture fisheries assessment methods inapplicable for making science‐based monitoring and management decisions. Three recent data‐limited approaches for marine fish stock assessments using length frequency and catch data (Length‐Based Indicators [LBI], Growth‐Type Groups Length‐Based Spawning Potential Ratio [GTG‐LBSPR] and Catch Maximum Sustainable Yield [CMSY]), were explored for applicability to assess stock status of three commercially exploited finfish species, Daysciaena albida, Eleutheronema tetradactylum and Mugil cephalus, in Chilika lagoon, an inland water body along the east coast of India. The LBI and GTG‐LBSPR approaches are based on catch length‐frequency data, while the CMSY is based on catch‐only data. The LBI provided insight into current exploitation status of the three species in relation to sustainable fishing, the GTG‐LBSPR provided reference points (RP) for the unfished portion of spawning biomass and relative yield in relation to selectivity, and the CMSY provided RPs for MSY, biomass and fishing pressure that yield MSY, to assess stock status and fishery management decisions. All three approaches suggested that the three species were overfished in terms of catch length and quantity, which agreed with expert knowledge of the fishery in the lagoon. All three approaches can support management and policy decisions in inland fisheries and fishery management recommendations. Future research should explore and standardise such approaches to overcome data limitations in assessing and managing inland capture fisheries.
