Evaluation of Compliance of Marine Fisheries of Kerala with Article 8 of FAO CCRF

It is necessary to evaluate the compliance of local fisheries with relevant provisions of the FAO Code of Conduct for Responsible Fisheries (CCRF) which is an indication of how far the code has been implemented. The present study focused on applications of the Code at the grassroot level by local fisheries m anagement authorities in marine fisheries of Kerala with reference to guidelines for fishing operations (Article 8 of FAO CCRF). A question- naire-based approach was used to demonstrate the compliance with the same. Study on marine fisheries of Kerala showed compliance on many areas of Article 8 like documentation of catch and effort, registration and licensing of fishing vessels, safety of fishers and insurance coverage. However, mesh size regulations as per section 4 of Kerala Marine Fisheries Regulation Act (KMFRA), 1980 were not followed. Other areas where improvement is required include Monitoring, Control and Surveillance (MCS), fishing gear selectivity and energy optimization. An overall 54% score was obtained for compliance of marine fisheries of Kerala with Article 8 of the code

Towards attaining sustainable fishing operations in Kerala

493-496Kerala is one of the major marine fish producing states of India contributing about 20% of the marine fish landings. FAO Code of Conduct for Responsible Fisheries (CCRF) is a tool which aims to attain sustainability through responsible fishing practices. Evaluation of compliance of marine fisheries of Kerala with provisions of Article 8 (Fishing Operations) of CCRF is an indicator of the level of implementation of the Code. In the present study, a self assessment questionnaire-based approach developed by FAO was used to gather information on the relevant sections of Article 8 of the Code from the selected experts using Google survey form for evaluation. The review of marine fisheries sector as per Article 8 of the code was done by 29 experts and an overall score of 45 percent, below the satisfactory level was obtained. This evaluation would facilitate State Regulatory authorities to suggest measures for enforcement, conservation and sustainable management of marine fisheries of Kerala

Taxonomy of BIllfishes

Billfishes are one of the apex predators in the pelagic food chain, distributed worldwide in the epipelagic waters of tropical and subtropical oceans. These fishes can disperse widely throughout the world oceans and spawn over broad geographic regions during a protracted season (Nakamura 1985). Billfishes are commonly seen within 200 m of the ocean water layer above thermocline but the occurrence up to 800 m is also reported. They are characterized by a prolonged upper jaw forming a long rostrum called bill and using the long bill to attack and stun their prey by moving their heads in various directions to make the prey unconscious and form a hassle-free prey capture. Sexual dimorphism is reported in billfishes with large sized females

Exploring the Effects of Various Polymeric Backbones on the Performance of a Hydroxyaromatic 1,2,3-Triazole Anion Sensor

Polymeric chemosensors are vital sensing tools because of higher sensitivity compared to their monomeric counterparts and tunable mechanical properties. This study focuses on the incorporation of a hydroxyaromatic 1,2,3-triazole sensor, 2-(4-phenyl 1H-1,2,3-triazol-1-yl)phenol (PTP), into polymers. By itself, the triazole has a selective, fluorometric response to the fluoride, acetate, and dihydrogen phosphate anions, and is most responsive to fluoride. Current investigations probe the suitability of various polymeric backbones for the retention and enhancement of the triazole’s sensing capabilities. Backbones derived from acrylic acid, methyl methacrylate, divinylbenzene, and styrene were explored. UV-illumination, Nuclear Magnetic Resonance (NMR) titration, and ultraviolet-visible (UV-Vis) absorption and fluorescence spectroscopy studies are used to investigate the performance of newly synthesized polymers and the derivatives of PTP that serve as the polymers’ precursors. Among the polymers investigated, copolymers with styrene proved best; these systems retained the sensing capabilities and were amenable to tuning for sensitivity

Not AvailableAn indigenous fishing technique practised in River Brahmaputra and two of its north bank tributaries namely Bhelengi and Chaulkhowa in Barpeta district of Lower Brahmaputra valley, Assam is described here. This particular fishing method involves catching of a predatory freshwater fish species Wallago attu (Bloch & Schneider, 1801) using Salmophasia bacaila (Hamilton, 1822), a small indigenous fish and Lamellidens marginalis (Lamarck, 1819), a freshwater bivalve as baits. Olfactory stimulation owing to the strong flavour and taste of the bait used is found to be the main reason of attracting highly predatory fishes like Wallago attuNot Availabl

Investigations on temperature dependent properties of spray deposited tin oxide thin films

The present study reported the temperature dependent properties of tin oxide (SnO2) thin films deposited by using conventional, cost effective and non-vacuum-based spray pyrolysis technique (SPT). The as deposited films were characterized by various characterization techniques such as X ray diffraction (XRD), UV-Vis spectroscopy and Scanning electron microscopy (SEM) to study their structural, optical and morphological properties respectively. XRD analysis revealed tetragonal rutile crystal structure of SnO2 with preferred orientation along (200) plane. The refinement of XRD data was also carried out by Rietveld refinement to obtain the fitting parameters, crystallite size and lattice parameters. UV-Vis study showed considerable change in optical absorbance and transmittance with change in substrate temperature. Effect of substrate temperature on film thickness, refractive index and band gap energy were determined by Swanepoel method and by Tauc’s plot respectively. The Urbach energy was also calculated and were correlated to the defects in SnO2 films. SEM micrograph showed the transformation from granules to nanospheres as a function of substrate temperature. Electrical properties were determined by Hall effect measurements which gives carrier concentration, electrical resistivity and mobility in the order of 1019-1020 /cm3, 10−2-10−3 Ω.cm and 4–23 cm2/Vs respectively
