Suitable Environment

The sea urchins, belonging to phylum Echinodermata, are a good source of “roe”, (gonads) and are being consumed by humans since pre-historic times. In many countries of the world, it is a delicacy among the food items and in retail markets in Japan, it is sold at prices as high as US$ 600 kg-1. Among the 800 species of echinoids, 105 species are found along the east coast of India and 30 species are recorded along the coast of Tamil Nadu. There is a paucity of information on the biology and ecology of sea urchins and lack of studies on its edibility and palatability. The sea urchin aquaculture called as echiniculture is picking up in subtropics and temperate areas. Importantly, the tropical marine ecosystem of India, which supports diverse flora and fauna is a suitable environment for echiniculture, and the future research needs to be focused to find out the potential species and developing techniques for their aquaculture. The present investigation analysed the landings of echinoderms in the Gulf of Mannar and Palk Bay along the south-east coast of India and also studied the gonadal maturity of two species of sea urchins viz., Salmacis virgulata and Temnopleurus toreumaticus in order to assess their suitability for echiniculture. S. virgulata and T. toreumaticus formed 70 and 30% respectively of the sea urchins landings at Vedalai and Pampan landing centres. The overall sex ratio of both the species did not deviate significantly from 1:1. In S. virgulata the mean monthly gonad index was highest (9.62±0.46) during September 2014 and for T. toreumaticus, the peak GSI was observed during December 2013. Further studies on captive maturation and breeding are needed to explore the potential of these species for echiniculture.

Most snacks are prepared from basically cereal flours which are nutritionally inadequate. There is the need to complement the nutrient content of these snacks by varying the food sources. Chin-chin snacks were produced from composite flours of Maize, soybean and OFSP with the following formation; sample A (50%: 25%: 25%), B (25%: 25%: 50%), C (25%: 50%: 25%), D (0%: 50%: 50%) and E (50%: 50%: 0%). Wheat flour (100%) served as the control F. The flour bends were analysed for functional properties while the chin-chin snacks were analysed for their nutrient and sensory qualities. The result of functional properties of the flours showed that bulk density of wheat flour (F) was the highest (0.746 g/ml). OFSP flour enhanced the water absorption capacity of the flour blends. Flour blends with soybean recorded higher values in foam capacity (11.20 - 22.55%). In proximate composition, the moisture was low (3.80 – 4.80%) in the chin-chin. Higher fibre content (2.60 - 4.20%) was obtained in samples containing higher proportion (50%) of OFSP. Samples D (19.38%) and C (18.80%) with higher soybean, recorded higher protein values. The mineral and the vitamin contents of snacks from composite flours were higher than that of the control F. Vitamin B1, B2, B3 and β-carotene contents of the snacks were enhanced by OFSP. The sensory evaluation showed preference for snack F (100% wheat flour) followed by snack A (50% maize, 25% soybean and 25% OFSP). However, improved nutrient dense chin-chin snacks were produced from the composite flours.

Polyvinyl alcohol (PVA) is a synthetic polymer, widely used for industrial applications, and its contamination related to the ecosystem concerns an increasingly serious problem. In the present study, we account a novel, potent PVA degrader, VVD-MBB8, isolated from the Gulf of Mannar. The VVD-MBB8 was identified as Enterobacter cloacae based on the molecular analysis using 16S rRNA gene sequence, biochemical and evolutionary distance analysis. This is the first report for the PVA degrader from the Enterobacter genus. The results showed 83% of the PVA present in the culture medium was degraded by Enterobacter cloacae VVD-MBB8 after 48 hrs of incubation with 30⁰C at the agitation of 145rpm. The results obtained from the FTIR showed notable differences in the PVA degradation stretches (3000 to 3300cm-1, 2500 to 3000cm-1) at 24 and 48 hrs compared with control (before degradation of PVA). The effects of carbon and nitrogen sources for PVA degradation were identified and the results revealed nitrogen sources have a significant increase in PVA degrading enzyme production and the enzyme activity was 83 U/ml.

AbstractThe peacock-tail shrimp Ancylocaris brevicarpalis Schenkel, 1902, is an obligate symbiont of sea anemones and well known for its remarkable colouration. Yet, very little information is available about its population structure and life-history traits, including reproductive parameters (fecundity, embryo volume and reproductive output). A total of 574 individuals were collected from the Gulf of Mannar, Tamil Nadu, India between February 2017 and July 2018, out of which 214 were males (37.28%), 355 were females (61.84%), and 5 (0.87%) juveniles. The highest percentage of individuals were observed in the post-monsoon season (38.10%) followed by monsoon (34.85%), pre-monsoon (15.02%), and summer seasons (12.01%). The overall sex ratio was skewed towards female individuals (0.55 male: 1 female). Fecundity was higher in females carrying early-stage embryos and embryo volume did increase, but not statistically significantly from early to late stages. The reproductive output was negatively allometric to the mean female body weight. The present study provides first-of-its-kind information on the population as well as individual-level reproductive characteristics of A. brevicarpalis.

Lined wrasse Anampses lineatus Randall was recorded off the coast of Tuticorin (Gulf of Mannar), Tamil Nadu, India for the first time. It is easily distinguished by the presence of pale longitudinal lines on the body following scale rows. Broad pale white and black color patch at the base of caudal fin is distinct. Morphological description of A. lineatus is provided based on the present material along with detailed distribution records; habitat and closely related species were also discussed.
