“…The mean concentration of trace metals in fish organs, seawater, and sediment was well within the permissible level as per the guidelines (WHO, 1989). However, considering that this location is a tourist hotspot, regular monitoring is required to estimate the metal concentration, develop a mitigation plan for promoting healthy habitats for flora and fauna, and contribute to coastal conservation and fisheries management (Murugan et al, 2005;Vijayakumaran et al, 2005;Kumar et al, 2009;Jha et al, 2017;Pandey et al, 2021;Pandey et al, 2022).…”

“…Currently, after imparting necessary professional skills, an attempt was made to examine n sh cage farming as an addition or an alternate to their livelihood in marine capture. Despite the vast pristine ocean space available in the coastal states ideal for mariculture, commercial sh farming in the country is still in its infancy (Jha et al 2017). Cage farming is not subjected to the same degree of uncertainty and risk attributable to environment parameters and inherent stock dynamics in uencing sh catch.…”

Artisanal fishers, fishing in nearshore coastal waters off Visakhapatnam using motorized crafts and in estuaries of Krishna using non-motorized crafts were selected for the study. Their annual net operating income varied between US$ 520.53 and US$ 2990.93, respectively. Inspired by the potential of cage farming from the frontline demonstrations in marine and estuarine waters, and after acquiring appropriate skills, 15 individuals from the Traditional Fishermen’s Co-operative Society, Visakhapatnam and 76 individuals from Yanadri Girijana Matsya Sakhara Sangam, Krishna embarked on cage aquaculture of Indian pompano in 15 and 70 cages. Marine cages were circular (6 m diameter) and estuarine cages were square (5 m X 5 m), and were stocked with hatchery-produced Indian pompano (Trachinotus mookalee) fingerlings of 22.6 g weight @ 2500 and 1500 numbers respectively, and were fed with floating pellets at 8 − 3% of biomass. Average body weight, survival and production from marine and estuarine cages were 843 g and 666 g, 96.28% and 91.47%, and 2029.0 kg and 913.85 kg respectively. Deducting all capital and operational expenses, annual net operating income per unit ranged from US$ 1383 to US$ 2917; which represented an improvement from that of capture-fishing. Cluster-cage farming, as adopted, did not adversely impact the water and sediment quality. Present study, provides virgin knowledge on bio-growth and economic parameters for commercial cage farming of Indian pompano, and when vigilantly replicated for marine and estuarine tropical waters offers immense promise as diversified or additional livelihood option for artisanal fishers in ensuring their economic sustainability.

“…It is well known that exclusion mapping may account for the majority of these features, nevertheless very few studies have been carried out (Barber et al, 2009) that combine them with physical and biological field data to determine site suitability. Site selection is a complex process in which the role of geographical information systems (GIS) is well established (Moeinaddini et al, 2010;Mousavi et al, 2015;Jha et al, 2017).…”

A planned artificial reef (AR) deployment program as part of a fisheries enhancement might be a useful tool for managers to supplement traditional ways to utilize available space and augment local productivity. Several AR deployment initiatives have been carried out globally, but they are rarely subjected to a rigorous site selection process. We created a site selection procedure in this study that includes systematic stages including exclusion mapping, underwater visual transect, benthic composition, seawater quality, and comparative visual mapping. This research focused on restoring the fishing grounds for artisanal fishermen by deploying AR along the southeast coast of India. The results of each stage in the procedure enabled us to choose suitable locations at a target depth with low wave action, no slope, and a good substrate capable of supporting an AR. Analysis of variance (ANOVA-one way) showed significant (p < 0.05) spatial variation for depth, slope, seawater current, salinity, chlorophyll-a, benthic density, and diversity. The geographical information system (GIS) based model output showed space allocation for AR deployment. The GIS methodology for site selection was developed to be easily adaptable to the demands of diverse artificial reef programs. The integrated strategy has proven to be a successful regulatory intervention for AR deployment practices in order to facilitate coastal restoration and management.
