“…The diversity was low in summer probably due to the shrinkage of water spread of the reservoir. The similar investigation by Naik et al [47] on ichthyofaunal diversity of Tunga Reservoir (Gajanoor Dam), Karnataka (India) and Naik et al [48] on assessment of fish biodiversity in upper Mullamari reservoir, Basavakalyan, Karnataka, (India).…”

The present study deals with ichthyofaunal diversity of Hiran-II reservoir, Gujarat. Sampling was carried out on monthly basis from January 2019 to February 2020. Total 23 species from 6 orders, 10 families and 19 genera were recorded during the present study. The range of water parameters such as temperature, pH, dissolved oxygen alkalinity and hardness were recorded and found suitable for fish production. Dominant family Cyprinidae with 12 species and 08 genera followed by Bagridae with 03 species 02 genera and other all families Claridea, Heteropneustidae, Cichilidae, Channidae, Gobiidae, Belonidae, Mastacembelidae, Poecilidae and Anguilidae contributed single species with single genera. Regarding conservation status out of 23 fish species 21 species least concern and 2 species near threaten. During month of December (post monsoon) highest fish diversity was found. Seasonal diversity indices such as Shannon-Wiener species diversity, Pielou's evenness, Margalef's species richness, were calculated based on the abundance of fish species to access the ecosystem health of Hiran-II reservoir. These studies will be help for the maintenance and regulation of Ichthyofauna and other aquatic ecosystem of the Hiran-II reservoir.

Vulnerability Assessment of Target Shrimps and Bycatch Species from Industrial Shrimp Trawl Fishery in the Bay of Bengal, Bangladesh

et al. 2022

Productivity susceptibility analysis (PSA) is a semi-quantitative ecological risk assessment tool, widely used to determine the relative vulnerability of target and non-target species to fishing impacts. Considering the available information on species-specific life-history and fishery-specific attributes, we used PSA to assess the relative risk of the 60 species interacting with the shrimp trawl fishery in the Bay of Bengal, Bangladesh. Penaeus monodon, the most important target, and Metapenaeus monoceros, the highest catch contributor, along with other 15 species were in the moderate-risk category, while seven non-target bycatch species were in the high-risk category. PSA-derived vulnerability results were validated with IUCN extinction risk, exploitation rate and stocks’ catch trend. The majority of the identified species showed high productivity (37%) and high susceptibility (46%), and all the moderately and highly vulnerable species were subjected to overfishing conditions by shrimp trawl fishery, which coincided with the vulnerability scores (V ≥ 1.8). Species with V ≥ 1.8 mostly showed a decreasing catch trend, while the species with a stable or increasing catch trend had a V ≤ 1.72. Data quality analysis of productivity and susceptibility attributes indicated that the majority of species were considered data-limited, which emphasizes the acquisition of data on spatio-temporal abundance, catch and effort, and biological information specifically relating to species age, growth, and reproduction. However, our findings can assist fishery administrators in implementing an ecosystem approach to ensure the sustainability and conservation of marine biodiversity in the Bay of Bengal.
