Targeting the non-target plant biota: Ecological implications of trawl fishery along Thoothukudi, Southeast coast of India

Assessing the ichthyofaunal diversity and trophic level from trawl bycatch of Chennai Fishing Harbour, Southeast Coast of India

“…Between the different seasons, the maximum similarity was seen between southwest monsoon and post-monsoon (39.31%). Ranjith et al (2018) showed the maximum similarity for seaweeds (53.31%) during summer and pre-monsoon and for seagrasses, maximum similarity (75.86%) during post-monsoon and monsoon. In this study, Leiognathus equulus contributed 7.97% (with 1.47% average similarity) to the total similarity of trawl bycatches of Chennai coast.…”

“…Similarly, Ramkumar et al (2019) found out 72.10% of seasonal similarities within the different seasons during 2013-14 for finfish bycatch along the northern Maharashtra coast. Ranjith et al (2018) estimated the SIM-PER for marine biota, which was exploited as bycatch along the Thoothukudi coast and revealed 34.68% similarity for the seaweeds and 49.38% for seagrasses. Between the different seasons, the maximum similarity was seen between southwest monsoon and post-monsoon (39.31%).…”

“…Bottom trawling is a pervasive source for benthic habitat, diversity, trophic structure, and community disturbance in the continental shelf of seas (Kaiser et al, 2002;Eastwood et al, 2007;Bijukumar and Deepthi, 2009;Foden et al, 2011;Ranjith et al, 2018;Ramkumar et al, 2019). Benthic habitat not only provides shelter and refuges for the juvenile but also serves as a major food source for demersal fishes (Kaiser et al, 2002).…”

“…estimated composition and trends in trawl bycatches on tropical fishing ground on Goa Samanta et al (2018). estimated the relationship between lunar cycle and shrimp trawl bycatches of Mumbai coast Ranjith et al (2018). estimated the diversity and biomass of plant biota, which are exploited as bycatch from trawlers along the Thoothukudi coast.Ramkumar et al (…”
