The diet composition and food habits of two species of Silverbellies, Karalla dussumieri (Valenciennes, 1835) and Gazza minuta (Bloch, 1795) from Mandapam vicinity of Gulf of Mannar was analysed. The diet composition was studied from December 2016 to April 2018. K. dussumieri with full stomachs appeared in very high percentages (100%) in December followed by empty stomachs (100%) in January and February. Empty stomachs were prevalent in most of the months for G. minuta with a peak in January (100%). The vacuity index (VI) of K. dussumieri was highest during January (100%) and minimum from September to December (11-21%). Correspondingly the highest fullness index (FI) was recorded during December (4.69). The monthly mean FI of G. minuta has shown a single maximum value during August (4.81), whereas the highest VI was noticed in most of the months with a peak in January (100%). Fishes of higher length group 105-110 mm and above had the highest FI in both species. The diet analysis of K. dussumieri revealed that a planktivorous feeding habit as copepods became the principal diet with an average %IRI of 32%, followed by foraminifera (26.12%). The monthly average %IRI values showed that G. minuta is a carnivorous fish with teleost fishes (50%) as the main food followed by shrimps (15%) and copepods (9%). The gut content of smaller fishes showed diatoms, polychaetes and amphipods as the main components and as they grew, more of nekton appeared in the stomach.

Vegetated habitats like mangroves, seagrasses and saltmarshes capture and store carbon and act as carbon sinks. The carbon captured and stored in these habitats, especially in the below-ground sediments, is called blue carbon. We report the blue carbon storage potential of seagrass habitats from the lagoons of Agathi, Bangaram, Kavaratti, Kalpitti, Thinnakara and Parli Islands of the U.T. of Lakshadweep. Sediment core samples were collected in triplicate from 30 cm deep from six stations located in the lagoons and estimated the organic carbon content in the sediment samples. The mean C org ranged from 0.1863 (Bangaram) to 0.3453% (Thinnakara); while the dry bulk density was 0.9115 (Kalpitti) to 1.1174 g/cm 3 (Kavarathi). Of the six Islands studied for blue carbon storage, the Thinnakara lagoon registered the highest level of 0.9795 mgC/ha and the Bangarum lagoon showed the lowest rate of 0.3796 mgC/ ha. Very low organic carbon stock in these lagoons indicated an urgent need for restoring and reviving the seagrass meadows, which are shrinking rapidly.

Mitochondrial oxidative phosphorylation genes play critical role in energy metabolism, aerobic potential and thermogenesis. These genes were thought to evolve neutrally, however increasing evidence suggests that mitogenome is susceptible to selection and adaptive variation. Organisms that have encountered selective forces to improve their metabolic potential or adapt to cooler environment can be suitable candidates to study the pattern and impact of selection on mitochondrial genome. Tunas, billfishes, butterfly mackerel and opah are the only teleost fishes to exhibit regional endothermy. They might have experienced strong selective forces to enhance their metabolic potential making them a suitable candidate group to search for positive selection. Mitochondrial protein coding genes of 16 regionally endothermic teleosts retrieved from NCBI GenBank were used to examine the pattern of selection using different ω -based approaches implemented in DATAMONKEY and TreeSAAP to analyze the changes in physicochemical properties of the amino acids. We found evidence for positive selection in different mitochondrial protein subunits across several branches of the phylogeny. Changes found in the subunits ND5 and ND6 might have modified the proton pumping efficiency and assembly of complex I respectively and the substitutions found in the subunit ATP6 might have an impact on the rotor performance of the complex V. Further studies on assessment of metabolic consequences of OXPHOS substitutions are essential to understand the importance of these substitutions on the performance of the fishes.
