“…For the first time, we show that the predicted distribution of shortbill spearfish overlaps highly with fisheries and may require a targeted management response, including intensified data collection to address the substantial data gaps. Precautionary fisheries management approaches could be applied mainly in the EEZs of the Western IO, where its niche is centred (S. M. Garcia, 1994; González‐Laxe, 2005; Karim et al, 2020). The high seas occupy approximately half of the study area and comprise the spatial distributions of most of the billfish species.…”

Background and aim: Billfish are epipelagic marine predators facing increasing pressures such as overfishing and rising global temperatures. Overfishing is a major concern, as they are caught by industrial longline fishers targeting tuna. Billfish are targeted by multiple fishing sectors, which provides food, socio-economic and cultural benefits. To support effective billfish management and conservation, it is essential to understand their spatial distribution and the environmental factors that may influence it. Location:The focus of this study is the Indian Ocean (IO), where there are gaps in understanding the interactions between fisheries and billfish distribution. Three of six billfish species are at risk from overfishing. Therefore, determining their distribution is crucial to their management and conservation.Methods: Using Ocean Biogeographic Information System (OBIS) occurrence data, Indian Ocean Tuna Commission (IOTC) catch data, and environmental covariates, we applied species distribution models to investigate the spatial extent of the realized niches of six billfish species in the IO. We also determined the role and relative importance of environmental drivers. Moreover, we evaluated the association between species' spatial distribution and the fishing effort distribution. Results:We found niche partitioning and overlap among the six species identified spatial distribution, with higher species richness in the northern region of the IO and off the East coast of Africa. Temperature, mixed layer depth and salinity were identified as the most important predictors of species distribution, with moderately warm and stable environments preferred by most billfish species. Areas with high species richness and high fishing effort overlap were primarily found in the Areas Beyond National Jurisdiction (ABNJ). In contrast, areas with high species diversity richness and low fishing effort were found mainly in the Exclusive Economic Zone (EEZ). Main conclusion: Spatial overlap between fishing effort and billfish projected distribution suggests inadvertent fishing pressure on billfish populations as they are caught together with targeted tuna.

“…Globally, marine fisheries catches have been declining steadily since peaking in 1996 Zeller 2016, 2019; Food and Agriculture Organization of the United Nations 2018). By contrast, the Indian Ocean basin seems to have experienced an ongoing increase in marine catches over time (Pauly and Zeller 2016), although there are concerns about localised resource depletions (Karim et al 2020). This divergent trend in catches has been variously explained by (1) a shift in global fishing effort to the Indian Ocean from historically overexploited regions elsewhere owing to the existence of stocks that might not have been overfished at that time (Worm and Branch 2012), (2) an increasing dependence of Indian Ocean rim countries (Indian Ocean Rim Association, IORA, www.iora.int/en) on marine fisheries (De Young 2006; Selig et al 2019), and (3) the very high uncertainty around official catch data from the Indian Ocean region, as the statistics of various fishing countries operating in the Indian Ocean may be unreliable (Pauly and Zeller 2016; Food and Agriculture Organization of the United Nations 2022).…”

“…This variety also affects the capacity of coastal countries to manage and control fisheries in the region, where a few examples of reasonably well-managed fisheries contrast with a general lack of management, regulation, control and enforcement (De Young 2006). Such a lack of effective management and enforcement capacity often results in development-driven policies in national fisheries that largely encourage unfettered and unsustainable growth and exploitation (van der Elst et al 2005(van der Elst et al , 2009De Young 2006;van der Elst and Everett 2015) and the substantial presence of illegal, unreported and unregulated (IUU) fishing in the region (Karim et al 2020;Samy-Kamal 2022).…”

Trends in Indian Ocean marine fisheries since 1950: synthesis of reconstructed catch and effort data

et al. 2023

Context Contrary to other ocean basins, Indian Ocean catches have increased consistently since 1950, although reported data are known to be incomplete. Fish is a crucial food source in the Indian Ocean; however, ineffective management often empowers over-exploitation. Aims We synthesised and reviewed Indian Ocean reconstructed catch and effort data by fishing sector and fishing country at the ocean-basin scale. Methods We aggregated reported and reconstructed unreported catch and effort data for the Indian Ocean and derived catch-per-unit-effort (CPUE) time-series by sector. Key results Indian Ocean rim country catches dominated in the Indian Ocean. Small-scale catches in the Indian Ocean have grown continuously by over 300% from 1.9 × 106 tonnes (Mg) year−1 in 1950 to 6.5 × 106 tonnes year−1 by 2018. By contrast, total industrial catches from the Indian Ocean have reached a plateau at ~8.5 × 106 tonnes year−1 since the late 1990s, after having steadily risen from very low levels in the early 1960s. Unreported catches declined from 45 to 25% of total catches. Total fishing effort, driven by the industrial sector, has increased 30-fold since 1950 from 0.4 × 109 to 11 × 109 kW-days by 2010, whereas CPUE has declined 78%, with steeper declines in the small-scale (>80% since 1950) than in the industrial sector (65% from its 1981 peak). Conclusions The different sectoral patterns in the Indian Ocean compared with other ocean basins are likely to be due to the region’s high dependence on small-scale fisheries and the later onset but swift growth of industrial fishing. The declining CPUE suggests strong decreases in stock biomass caused by strongly increasing fishing effort, especially in the industrial sector. Implications Indian Ocean countries should prioritise lower-impact well-managed domestic small-scale fisheries to maximise long-term, sustainable nutrient supply for local livelihoods.

“…Some people believe that the fishery industry is facing critical threats and risks as a result of anthropological activities such as overfishing, which destroys aquatic ecosystems (Zeng et al 2022). Another group believes that underdevelopment management is a major threat to the fishery industry (Karim et al 2020). A top-down strategy can help maintain the resources of the fishery industry in most developing countries (Samian et al 2017).…”

Fisheries within India have significant financial, nutritional and socio-economic development prospects. The country has a diversified natural fishery resource. Fishermen have continuously undertaken fisheries activity throughout the country over decades and fisheries co-operatives have now been developed for cumulative production and effective regulation of fishery activities. It was observed that there have been many inconsistencies, mostly in the management of fisheries co-operatives; a few were effectively handled under active supervision and government backing, whereas many co-operatives are facing various problems for their existence. Effective administration of fisherman's co-operatives is critical for increasing fishing productivity and the socio-economic growth of fishermen. Co-operatives can help fishermen develop their skills and gather information about technology, marketing, and management. Co-operatives can improve productivity, processing, storing and transportation capabilities while also meeting financial demands. As a result, co-operative organisations may contend with multinational corporations by integrating competent management abilities with co-operative power. To do this, a nationwide research project focusing on different elements of fisheries co-operatives is recommended. The need for appropriate policy implications for such sustainable management of fisheries co-operatives in accordance with current technical advancements in the sector of aquaculture, environmental degradation and global warming has been highlighted.
