“…The Lakshadweep archipelago includes a group of ten inhabited and 17 uninhabited islands, under the jurisdiction of the Government of India, scattered between 08°16′–13°58′N and 71°44′–74°24′E in the Southern Arabian Sea. Tuna is the major fishery (86.5%) in the region with an estimated landing of 13,500 tonnes per year (Vinay, Ramasubramanian, Krishnan, Kumar, & Ayoob, ), followed by needlefishes of the family Belonidae which contributes to the second largest fishery. Owing the better texture, flavor, colour and superior meat quality, there is a good demand for this fish especially during “off season” (monsoon months), when tuna fishery declines.…”

Length‐weight relationships (LWRs) of three needlefishes belonging to the family Belonidae viz., Ablennes hians, Tylosurus crocodilus and Tylosurus acus melanotus were estimated based on samples exploited from a gill‐net fishery in Androth, an island in the Lakshadweep archipelago. The estimated allometric co‐efficient b value ranged from 3.047 (T. acus melanotus) to 3.274 (A. hians), and r2 value ranged from 0.911 (T. acus melanotus) to 0.973 (A. hians). The first estimate of LWR for these three commercially exploited needlefish species from the Lakshadweep islands indicate local populations to be fairly robust and forms a basis for future management of fishing stock in the region.

“…Scombridae constituted the major catch out of the fishes sampled. The islanders' major source of income is tuna fishing, which takes place for roughly six months, from October to April and forms the major resource (Vinay et al 2017). Tunas are highly migratory, effective epipelagic predators found more prevalent in the Indian exclusive economic zone's oceanic island regions, particularly Lakshadweep (Kumar et al 2020).…”

“…The fisheries in the Lakshadweep Islands have always been sustainable and subsistence oriented. Tuna and needlefish account for around 95% of the total commercial fisheries in the Lakshadweep Islands, where fishing is the primary source of income (Vinay et al 2017). These fishes have traditionally been caught with troll line, pole and line, handline and drift gillnet.…”

The Lakshadweep Islands are well-known for their abundant fishery resources. Present study primarily focused on the systematic representation of IUCN (International Union for Conservation of Nature) Red Listed marine finfish landings of Chetlat Island of Lakshadweep archipelago (India). Monthly collections were carried out from September 2019 to February 2020 from the study area. A list of finfishes along with their scientific name, common name, family, and present conservation status was prepared. As per the IUCN Red List, out of 41 fish species identified, one species is ‘Endangered’ (EN), two species are ‘Near Threatened’ (NT), four species are ‘Vulnerable’ (VU), one species ‘Data Deficient’ (DD), 29 species ‘Least Concern’ (LC), and four species are ‘Not Evaluated’ (NE) categories. Information on the conservation status of fishes plays a significant role in fisheries science since it forms the basis for managing marine fishery resources.

“…It has a shelf life of more than 1 year. According to a study, tuna account 15.83% of Indian total tuna landings and 86.5% of fish production of Lakshadweep islands (Vinay, Ramasubramanian, Krishnan, Kumar, & Ayoob, ). Out of it, 90% of total tuna landings is converted into Masmin that generate an average revenue of Rs.…”

Masmin preparation is a traditional method that has been practiced for many years to preserve skipjack tuna (Katsuwonus pelamis) mainly in Lakshadweep. However, the method is not evaluated scientifically for its quality concerning nutrition and environmental contamination. Thus, in the present study tuna fillets from four stages of Masmin preparation, namely fresh, boiling, smoking, and sun‐drying are evaluated for bacterial, nutritional, and heavy metal contents. The analysis revealed no significant difference in bacterial load, proximate nutrition (p = .93) and essential minerals, and heavy metals (p = .94) among all stages, suggesting the final product “Masmin” is nutritionally equivalent to the fresh tuna. However, pathogenic bacteria, such as Vibrio harveyi, Pseudomonas spp. Bacillus spp. are found, indicating poor hygiene during the processing. Heavy metals concentration like Al, Cd, Co, Cr, Mn, Ni, Zn, and Pb has increased with respect to previous reports, indicating an increase in pollution level in the catchment area that demands proper monitoring. Practical applications The findings inform the personnel engaged in Masmin preparation and consumption about the nutritional value of Masmin which is comparable to the fresh tuna even after different processing stages. Thus, the traditional fish preservation method could be applied to other economic important fishes where the cold facility is limited for fish preservation. On the basis of the microbiological analysis, we recommend the use of solar dryer and smokers in a traditional method of Masmin preparation to reduce microbial and dust contamination during processing and also it reduces the processing time that ultimately increases the production rate. Further, the findings from the heavy metal analysis bring into notice the increase in pollution level in Lakshadweep that raises health concern for the island populations and consumers.
