“…The lower growth rate obtained during the present study may be due to the comparatively higher stocking density, which needs to be sized down in the future trials. The daily growth of E. suratensis recorded was found to be lower than the earlier report of 120 -130 g in 6-8 months by Padmakumar et al (2012). The lower growth rate reported here could be attributed to the high saline condition that prevailed during the culture period.…”

Integrated multi-trophic aquaculture (IMTA), farming of species from different trophic levels and with complimentary ecosystem function, is regarded as a suitable approach to develop a sustainable aquaculture system. In order to establish an IMTA system, a study was carried out in Sindhudurg District, Maharashtra, India for selected tropical brackish-water species. Two equal sized pens (250 m2) were constructed for IMTA and control respectively in each land based system and open water cages were set in the estuary. Different combinations of fed species (Chanos chanos, Etroplus suratensis, Mugil cephalus, Penaeus indicus) and an extractive crop (Crassostrea madrasensis) were stocked in IMTA experimental system whereas monoculture of P. indicus served as control. Water quality characteristics were found to be within the admissible limits. Soil organic carbon was found to be lesser in the IMTA system compared to control. The productivity of IMTA system was higher than control: 3250 kg h-1 vs 2000 kg ha-1. Further, income and benefit-cost ratio was found to be higher in IMTA pens. The present study concludes that IMTA is a possible option for system diversification as well as species diversification without compromising economic profitability of culture.

“…The backwaters of Kerala are the potential source of its seed. This commercially important species is a symbol of delicacy in the backwater tourism and treated as the 'state fish' of Kerala (Padmakumar et al, 2012). The fish was reported to constitute almost 10% of the total landings from these backwaters during 1960's (George and Sebastian, 1970).…”

“…Previous research on this endemic species focused on its biology (Jayaprakas, 1980;Vijayaraghavan et al, 1981;Jayaprakas et al, 1990;Bindu andPadmakumar 2008, 2014), reproduction (Padmakumar et al, 2009a(Padmakumar et al, , 2012, phylogenetic diversity (Sachithanandam et al 2012) and culture (Padmakumar et al, 2009b). Fishery of this species in Vembanad Lake was documented by Unnithan et al (2001) and Padmakumar et al (2002).…”

The present study investigated catch and size composition of Etroplus suratensis (Bloch, 1790), based on the data collected from two main fishing practices common in the Vembanad Lake, South India. Both the fishing practices viz., gillnetting and scare line fishing were in vogue round the year and the landings showed considerable variations. E. suratensis constituted 49% of the gillnet landings, while scare line fishing is exclusively for this species. In Kumarakom region of the lake, the estimated annual landings of E. suratensis by scare line and gillnet varied from 14,369 to 30,232 kg and 1,747 to 2,142 kg respectively during the study period. Size distribution studies showed that young ones constituted a significant proportion of gillnet landings, whereas subadults and adult fishes were more in scare line catch. Length-weight relationship showed isometric growth pattern with b values of 2.890 and 2.700 for gillnet and scare line fishing respectively.

“…E. suratensis is one of the most sought after candidate species for brackishwater aquaculture in Kerala due to its suitability for culture in confinement along with tolerance to a wide range of environmental conditions (Chandrasekar et al, 2014). E. suratensis is designated as the 'State fish of Kerala', with backwaters of Kerala being the major source of the wild population and a potential source of its seed (Padmakumar et al, 2012). Wild populations of E. suratensis are facing habitat deterioration due to increasing urbanisation, tourism activities in backwaters/ estuaries and threats from proliferation of exotic species like Oreochromis mossambicus and Trichogaster trichopterus (Padmakumar et al, 2002;Kumar et al, 2009).…”

Attempts have been made for captive breeding aimed at conservation along with the creation of aquatic sanctuaries/no fishing zones, within some of the larger estuaries (Padmakumar et al, 2012).…”

The complete mitochondrial genome and phylogeny of the green chromide, Etroplus suratensis (Bloch, 1790) from Vembanad Lake, Kerala, south India

The green chromide Etroplus suratensis (Bloch, 1790), is a cichlid species which forms an economically valuable food fish and a preferred candidate for brackishwater aquaculture in India. The complete mitogenome of E. suratensis collected from Vembanad Lake, Kerala, India has been characterised in the present study. The entire mitogenome was PCR amplified as contiguous, overlapping segments and sequenced. The assembled mitogenome of E. suratensis is 16456 bp circle, contained the 37 mitochondrial structural genes, two ribosomal RNA genes (12S rRNA and 16S rRNA), 22 transfer RNA (tRNA) genes, 13 protein-coding genes and 1 non-coding control region/D-loop, with the gene order identical to vertebrates. In the phylogenetic analysis, E. suratensis is clustered with other Indo-Sri Lankan taxa. Among cichlids, the groups from South America and Africa are monophyletic in origin. The mitogenomic information generated in this study will be valuable for further studies on evolution, taxonomy, conservation, environmental adaptation and selective breeding of this species having aquaculture, ornamental and evolutionary importance.
