The hooks and line fishery for sharks by the migrated fishermen from Kanyakumari was noticed at Thai and Korlai centres of Janjira-Murudregion, Raigad District, Maharashtra. The fishery commences In November and extend upto May

Unusual landing of Hilsa ilisha and Rastrelliger kanagurta at Raigad region of Maharashtra

Presently there are three landing centres in Raigad Disrict under regular operation during monsoon fishery viz., Alibag, Borli-Mandla and Nandgao-Mazgao. In these landing centres, fishes caught during monsoon fishery by gillnet operation are landed where good catch of Hilsa ilisha and Rastrelliger kanagurta are obtained

Unusual landing of Penaeus juveniles by bag net operation (boxinet) at Tevhanda Creek

On 23rd and 24" June 2005, there was an unusual landing of Penaeus merguiensis (5- 7 cm total length) juveniles at Janjira Murad to the tune of 20-35 Kg by non- mechanized craft using boxinet

Observations of the coastal area consequent to collision of two ships near the Gateway of India, Mumbai

A visit was undertaken in and around Alibag which was reportedly affected as a result of spillage of oil in the sea due to collision of two ships near JNPT Port. It was noticed that there were huge quantities of tea/coffee powder bags, biscuit packets and empty plastic bags soiled with oil, spread all over the beach area of Navgaon, Thal, Mandwa, Saswane and Rewas Bodni

On the incidental heavy catch of prawns and mackerels at two landing centres along Raigad District, Maharashtra

An unusual heavy catch of the banana prawn, Penaeus merguiensis was landed at f^amde landing centre on 10-4-'97 landed by the gill net locally called Daran Jal. Nine gill nets operated from the dug-out canones. Wahan hodi in the Rajpuni creek at a depth of 4-5 m landed a total of 304 kg of P. merguiensis which fetched a price of Rs. 35/- per kg

Honeycomb stingrays (Himantura uarnak) washed ashore at Uran coast in Maharashtra

About 50 to 55 numbers of the honeycomb stingray, Himantura uarnak (Fig.1) were washed ashore at Mankeshwar beach near Uran coast in Raigad District of Maharashtra on 21st August 2010. These fishes were about 4 feet long and about 3 feet in disc width

On the stranding of a dolphin at Janjira Murud, Raigad distirct, Maharashtra

A dead dolphin measuring about 2.5 m in total length was stranded ashore on 15-11-'97 at Janjira- Murud, Ralgad District, Maharashtra (Fig. 1). Due to itsdecomposed condition, clear identity could not be ascertained but indicated close affinity to the common dolphin, Delphinus delphis

Evaluation on the Corrosion of the Three Ni-Cr Alloys with Different Composition

Dental casting alloys are widely used in contact with oral tissue for many years now. With the development of new dental alloys over the past 15 years, many questions remain unanswered about their biologic safety. Concepts and current issues concerning the response to the biologic effects of dental casting alloys are presented. In this paper, samples of three commercially available nickel-chrome (Ni-cr) casting alloys (Dentaurum, Bego, Sankin) were taken to assess their corrosion behavior, using potentiodynamic polarization method (electrochemical method) with fusayama artificial saliva as an electrolyte medium to check for their biocompatibility. The parameters for corrosion rate and corrosion resistance were obtained from computer-controlled corrosion schematic instrument, namely, potentiostat through corrosion software (power CV). The results obtained were analyzed by classic Tafel analysis. Statistical analysis was done by Student's t-test and ANOVA test. It was concluded that Dentarum and Bego showed satisfactory corrosive behavior, with exception of Sankin which depicted higher corrosion rate and least resistance to corrosion. Thus, the selection of an alloy should be made on the basis of corrosion resistance and biologic data from dental manufactures
