Seasonal influence on settlement, distribution and diversity of fouling organisms at Mumbai harbour
نویسندگان
چکیده
Biofouling at two sites was examined with regard to species abundance (density) and its composition. Sixty species were recorded during the investigation period (2000 – 2001). These species mainly belong to phylum annelida (11 species), bryozoa (22 species), cirripedes (4 species), mollusca (5 species.), coelenterata (6 species), tunicata (10 species) and porifera (2 species). Thirty five species have been recorded from tidal basin. Which is influenced by organic pollutants released through sewage water. Among sixty recorded species, 16 were new records from the region. There is significant variation in density from month to month at Near-shore waters and at Tidal basin. Species settled in pre-monsoon were significantly higher than species settled in monsoon and post monsoon. Settlement pattern varies with seasons at Near-shore waters and at Tidal basin.

Marine fouling on test panels and in-service structural steel in Tuticorin harbour
As more and more structural materials are used in marine and offshore service, studies on the effects of fouling organisms on corrosion and cathodic protection phenomena have gained renewed importance. This communication describes the common fouling organisms of Tuticorin harbour and their possible association in corrosion processes. Earlier studies on fouling in Tuticorin waters are restricted...
متن کاملHydration and chain entanglement determines the optimum thickness of poly(HEMA-co-PEG₁₀MA) brushes for effective resistance to settlement and adhesion of marine fouling organisms.
Understanding how surface physicochemical properties influence the settlement and adhesion of marine fouling organisms is important for the development of effective and environmentally benign marine antifouling coatings. We demonstrate that the thickness of random poly(HEMA-co-PEG10MA) copolymer brushes affect antifouling behavior. Films of thicknesses ranging from 50 to 1000 Å were prepared vi...
متن کاملLow densities of epiphytic bacteria from the marine alga Ulva australis inhibit settlement of fouling organisms.
Bacteria that produce inhibitory compounds on the surface of marine algae are thought to contribute to the defense of the host plant against colonization of fouling organisms. However, the number of bacterial cells necessary to defend against fouling on the plant surface is not known. Pseudoalteromonas tunicata and Phaeobacter sp. strain 2.10 (formerly Roseobacter gallaeciensis) are marine bact...
متن کاملField experimental evaluation of secondary metabolites from marine invertebrates as antifoulants.
The crude organic extracts of the endemic gorgonian Phyllogorgia dilatata and two sponge species Aplysina fulva and Mycale microsigmatosa were evaluated for anti-fouling properties through field experiments. To investigate this property in ecologically meaningful conditions, crude extracts from these invertebrates were incorporated at concentrations naturally found in these marine organisms int...
متن کاملThe interaction of marine fouling organisms with topography of varied scale and geometry: a review.
Many studies have examined the effects of surface topography on the settlement behaviour of marine organisms and this article reviews these investigations with more emphasis on the effects of topography scale. It has been observed that macro topographies (1-100 mm) are generally favoured by marine fouling taxa and are unsuitable for antifouling applications. This is because macro topographies a...
