T.; Prakash, S; Rao, R. Vishwas; Gunasundari, V. Abstract: Two goby fishes Cryptocentrus cyanotaenia Bleeker, 1853 and Istigobius diadema Steindachner 1877 were collected from the Tuticorin and Mandapam coastal waters of Tamilnadu, India. C. cyanotaenia is well distinguished by the presence of grey color body with 9 narrow white bars; blue lines and spots with markings on the head and snout; yellow margins of dorsal, anal and caudal fins. I. diadema is easily recognized by bold black line on the posterior portion of the eye; head region with a dark reddish tinge; dorsal, anal and caudal fins with dark spots.

(Nematoda: Philometridae) infection in the ovary of Lutjanus russelli (Bleeker, 1849) in southeast coast of India Authors: Selvakumar, P.; Gopalakrishnan, A.; Sakthivel, A. Abstract: Prevalence and intensity of an ovarian nematode parasite, Philometra sp. (Philometridae) and its effect on reproductive potential of marine fish has been investigated. Fish was collected randomly from south east coast of India. Live Philometra sp were represented solely by females and found only in the ovary of mature fish caught in the spawning period of Lutjanus russelli. Fishes were measured length and weight. The normal and infected ovaries were carefully removed from dissected fishes and examined the prevalence of nematode infection for each fish. Than the nematode were carefully removed and washed in a 0.6% saline solution and fixed in 70% ethanol. Representative nematodes were clean with glycerin and fixed in a solution of 95% glacial acid and 5% formalin for identification for light microscopy (LM) examination. Since the ovary were maligned during that period, particularly ovaries would provide an abundant food source in the form of blood. Maximum prevalence in Kalpakkam and Poompuhar, the prevalence was 78.1 % and 87.8 % in summer and post monsoon season respectively. Minimum was reached in Point Calimere coast in post monsoon, summer, pre monsoon and monsoon season is 16.3 %, 25.9%, 29.4 % and 38.6 % respectively. The overall prevalence was 69.5±26.872 % in post monsoon, 53.4±19.254 % in summer, 55.6±22.273 % in pre monsoon and 73.3±18.140 in monsoon seasons.

Abstract: In the present report attempt is made to in depth survey of the species Sonneratia L. throughout Maharashtra and its analysis for biochemical, elemental composition, species dynamics and the distribution of the species along the coast. Carbohydrate composition varies from species to species. Protein content is more in all the three species followed by polyphenols. The elemental composition is also varies and is species specific. Chlorides concentration in S. alba is more indicating succulence and sulphate requirement in S. apetala indicates its non succulence. Amino acids content in S. caseolaris is more may used in osmoregulation.

Raja Abstract: Present study consists the stydu of status of some marine algal flora in relation to their occurrence, distribution status and diversity. Sampling was done along six stations between May, 2013 and December, 2013. A total of 34 marine macro-algae species were recorded, of which 12 species belong to Chlorophyta, 6 species to Phaeophyta and 16 species to Rhodophyta. The Species Ulva fasciata Delile, Chaetomorpha antennina (Bory) Kutzing, Amphiroa fragilissima Camouroux and Gracilaria corticata J.Agardh were found to be dominant in all the stations and are found to be widely distributed along rocky areas of the coast of Visakhapatnam.
