Dead Bryde's whale washed ashore at Veraval, Gujarat

Bryde’s Whale (Balaenoptera edeni Anderson, 1879) measuring 10.4 m in length and weighing about 7 tons was found washed ashore on the beach of Veraval on 4th august 2017. Locally called as “Machchh” it was found in dead condition with small injuries in the caudal peduncle and genital region. With the intervention and supervision of forest officials, it was towed ashore and a veterinary officer conducted post-mortem after which it was buried on the shore. Occurrenc

Case study on dol net fishing operation and its economic analysis off Gujarat, north-west coast of India

Dol net is traditionally used for fishing along the north-west coast of India. In this study, the operational as well as economic aspects of dol net operation off Navabandar, Gujarat was studied. Dol nets operations from mechanised boats locally called as Van along Navabandar coast were considered for the present study. The overall length (OAL) of the mechanised vessels were in the range, 10-12.8 m with 2.4-3.6 m breadth and 1-1.8 m height. The total capacity of vessels was in the range 15-20 t and average fish holding capacity was 2.5 t. The fishing vessels had six cylinder engines of 87 to 105 hp. Fishermen themselves fabricated the nets for the dol net, which had seven different parts with various lengths. Kaba-sus system using steel pipes was the method of dol net fishing off Navabandar. They were locally known as Bochi, Patiya, Aor, Trijo, Bangu, Chothi and Jalo. The study indicated that the profit of a dolnetter at Navabandar in a year was `2,88,122

GIS based mapping of spatio-temporal distribution pattern of ribbonfish Trichiurus lepturus (Linnaeus, 1758) along Saurashtra coast, India

Identification of spatio-temporal distribution of fish species represents fundamental information for stock assessment which in turn is essential for formulation of fishery management plans as well as for GIS based decision making. This study investigated the spatio-temporal distribution and abundance of different life stages of ribbonfish, Trichiurus lepturus (Linnaeus, 1758) off Saurashtra coast. Geographical coordinates of fishing and allied information on the time of fishing, depth of the fishing area as well as catch details were collected using a structured schedule, from selected trawlers operated from Veraval. Information was mapped using a GIS software to get the spatio-temporal distribution of the species. It was observed that juveniles were more abundant along the south Saurashtra coast whereas subadults and adults showed a discontinuous distribution with abundance in the waters off south Saurashtra as well as north Saurashtra coasts

Correlation of phytoplankton density with certain hydrological parameters along the coastal waters of Veraval, Gujarat

The present study was conducted to study the biological diversity of phytoplankton and the impact of abiotic factors on them along coastal waters at two locations viz., Location-1 (Jaleshwar) and Location-2 (Sagareshwar Mandir), Veraval from May 2012 to April 2013. Six classes of marine phytoplankton were identified from these locations. Out of the total 162 species of marine phytoplankton collected, nine could not be identified. Diatoms were the dominant group (133 spp.) followed by dianoflagellates (12 spp.), blue-green algae, brown or orange chromatophores and green algae. The correlation between the density of phytoplankton with the environmental variables viz., Dissolved Oxygen and pH were significantly positive, whereas it was inversely correlated with temperature and salinity. The density of phytoplankton, ranged from 4,90,495 to 8,57,160 cells L-1 and 3,87,495 to 8,65,665 cells L-1 at Location-1 and Location-2 respectively. Phytoplankton cell count was the highest and lowest in January and March respectively and the diversity was higher in winter than other seasons. The diversity of marine phytoplankton was very high along the coastal waters of Veraval (at both the locations of study) which confirms that the Veraval coastline is very productive and supportive for fish production and also for other marine biodiversity

Self-help Group earn profit from cage farming The Times of India dated 14th August 2021

Synthesis and Characterization of Iron oxide Nanoparticles with Thymoquinone

Nigella sativa is a medicinal plant used for its antimicrobial properties. Thymoquinone (TQ) being the lead component of this plant seeds, exerts antibacterial, antifungal and antioxidant activity. It has also shown promising activity against cancer and inflammation through different modes of action. In recent developments for new applications in the field of medicine, nanotechnology has excelled as a very prominent and important field. Nanoparticles are generally in the dimension range of 1–100 nm. Iron oxide nanoparticles show enhanced antibacterial activity against gram-negative bacteria. The current research focuses on comparing the yield, stability and purity of thymoquinone synthesised iron oxide nanoparticles using different organic solvents, the benefits expressed by thymoquinone as a herbal drug and a novel approach to green synthesis of iron oxide nanoparticles with thymoquinone and testing for their stability, size and functional groups
