in less than 150 words) Negombo Lagoon is one of the most productive and sensitive ecosystems in Sri Lanka. The main fresh water input comes to this lagoon from the rivers Dandugam Oya and Ja-ela. The Negombo Lagoon and its coastal environment have had a long association with the fishery industry. The salinity of Negombo Lagoon is strongly related to the monsoon rains and varies from almost zer...

Assessment of socio-economic issues of fishing community is an important aspect in framing a strategy for the preservation of eco-systems which leads to sustainable lagoon management. The present investigation analyses the current potential socio-economic status of the fishing community of Pulicat lagoon, the second largest lagoon in India. The socio-economic indicators considered in the study ...

The concentrations of malodorous compounds in a 0.4-ha anaerobic lagoon that received waste from approximately 2000 sows were monitored during the late summer to late fall of 2006 to gain insight into the factors influencing their concentrations. Selected malodorous compounds were measured by the use of equilibrium samplers consisting of submersible stir plates and stir bar sorbtive sampling wi...

A study was conducted to determine the effects of solid‐liquid separation of liquid swine manure on ammonia emissions from lagoons. This determination was done at full‐scale in two contiguous swine production units that had similar animal production management. One of these units was maintained as a control using the anaerobic lagoon treatment method. In the second production unit, solids were ...

Radium isotopes (Ra, Ra, Ra, and Ra) and water chemistry were used to identify two chemically distinct sources of submarine groundwater discharge (SGD) in Celestún Lagoon, Yucatán, Mexico. Low salinity groundwater discharging from springs within the lagoon has previously been identified and extensively sampled for nutrient concentrations. However, a second type of groundwater discharging into t...

The helminth communities of silverside, Odontesthes bonariensis (Valenciennes, 1835), from two Argentinean lagoons were studied and compared at component community and infracommunity levels. Nine helminth species were found: five digeneans (Austrodiplostomum cf. mordax, Ascocotyle (Phagicola) cf. diminuta, Ascocotyle sp., Thometrema bonariensis and Saccocoelioides sp.); two nematodes (Contracae...

The Sand Motor is a mega-nourishment characterized by a very large sand volume of around 20 million m placed along the Dutch coast. The Sand Motor is a pilot project to evaluate the performance of an alternative nourishment strategy with respect to different functions of the coastal system. Within the scope of the coastal functions, the hook-shaped design of the initial morphology of the Sand M...

Seasonal and diel variations in community structure and abundance of the lagoon hyperbenthic community were examined at Davies Reef, Great Barrier Reef. The lagoon floor community differed from that in the overlying water, it was faunistically more uniform, and it was assembled into statistically distinct seasonal and diel groupings. The lagoon floor community was characterized by reef-associat...

The Anzali Ramsar Convention wetland is located in an ecologically and economically important region in Iran. The wetland is largely surrounded by agriculture, natural forests and rangelands (approximately 36% and 63%, respectively). Urban areas consist of less than 1% of the total area. Urban land use produces the highest rates of nutrient transfer into the lake as TN, TP and BOD5 equal to 24,...
