    Description: Ichthyofauna was studied in the inshore waters around the Great Nicobar Island to assess the extent of biodiversity of fishery resources in the Great Nicobar waters by using various gears and crafts. During the present study, 258 species of fin fishes belonging to 141 genera, 84 families and 19 orders were recorded. Among these, Perciformes topped the list with 47 families, 84 genera and 169 species followed by Clupeiformes, Angulliformes, Tetrodoniformes, Cyprinodontiformes, Scorpaeniformes, Rajiformes, Elopiformes, Pleuronectiformes, Syluriformes, Laminiformes, Bercyformes, Aelopiformes, Syngathiformes and Gonorhychiformes which includes the medicinally important and ornamentally valuable species.

    Notes: The crystal structure of the title compound, 2C9H12NO2+·SO42−·H2O, consists of two protonated phenylalaninium cations linked together by hydrogen bonding with the water molecule and the sulfate anion. The aggregation of the hydrophobic zone is along (10\overline 1) and of the hydrophilic zone is along (20\overline 2). The phenylalaninium molecules show sterically least favourable g+ or g− conformations.

    Notes: In the title compound, 2C6H15N2O2+·H+·ClO4−·2Cl−, the two mono- and dicationic lysinium molecules are held together by strong O—H...O hydrogen bonds. Both the perchlorate and chloride anions link molecules 1 and 2 through the α-amino and ε-amino groups into infinite chains along the a axis. The aggregation of the hydrophilic groups is along the z = 0 plane and that of hydrophobic is along the z = 1 \over 4 plane. Molecule 1 is engaged in a zigzag (Z1) head-to-tail sequence.

    Notes: In the title compound, C8H10NO2+·ClO4−, the phenylglycinium cation is linked to the perchlorate anion through a normal O—H...O [2.78 (2) Å] hydrogen bond. The phenylglycinium cation and perchlorate anion are also held together by N—H...O hydrogen bonds. Chelated three-centered hydrogen bonds are observed involving the amino-N atom and the perchlorate-O atoms. The molecular aggregation of the hydrophilic zone at z = 1 \over 4 is sandwiched between two hydrophobic zones.
