  Citation × Citation Citation Abstract Copy Title: Economic Valuation of Mangroves for Assessing the Livelihood of Fisherfolk: A Case Study in India Author: DebRoy, Piyashi, Jayaraman, R. The study was carried out in a village named MGR Thittu in the vicinity of the Pichavaram mangroves in the state Tamil Nadu in India. The objectives of the study were to review the current status of mangroves in Tamil Nadu, study the fisherfolk’s perceived role of mangroves on their livelihood, estimate the economic value of mangroves as a case study, and suggest policy measures needed for the conservation, protection, management and development of mangroves. The required data were collected randomly from 41 experts and 120 villagers. The most important concern for protecting the mangroves was found to be strengthening of coastline against Tsunami through mangrove plantation. The most important present use of the Pichavaram mangroves was their services through their ecological functions like protection against tsunami, floods and heavy winds; followed by contribution to fishery; and firewood collection. In calculating the Total Economic Value of the concerned mangrove area, the values were divided according to direct use values, indirect use values and willingness to pay estimates, and was added upto be Rs. 353,52,31,312. The economic valuation of the particular mangroves attributed an indicative price to the huge value of the mangrove resources, which is necessary for investing in protecting natural resources on the part of the government and other stake holders for protecting fisheries resources in the view point of sustainability.

  Citation × Citation Citation Abstract Copy Title: The Value of Environmental Impact of Fisheries on Nutrient Dynamics Author: Virtanen, Jarno The Baltic Sea is referred as the most polluted sea in the world. The most serious problem is the eutrophication that is a consequence of nutrient loading through human based activities. Nutrient enrichment has led to growth of phytoplankton that has induced increased algal blooms and oxygen depletion in the sea bed that have resulted to changes in ecosystem balance. Conservation needs of the Baltic Sea are directed by HELCOM, the intergovernmental body on protecting Baltic Sea. The HELCOM Baltic Sea Action Plan objective is to restore the good ecological status of the Baltic marine environment by 2021. The agreement set up country-wise annual reduction targets for phosphorus and nitrogen loadings. Every member state should define their abatement measures in a cost efficient manner. The cost estimates for nutrient abatement varies significantly depending on the measures taken. Apart from abatement measures fisheries have a significant role in nutrient dynamics in the Baltic Sea. It is estimated that the phosphorus removal of fisheries accounts for 18% of anthropogenic load; corresponding share in nitrogen is 2.4%. Using the cost estimates of different abatement measures it is possible to estimate the shadow value of the positive environmental impact of fisheries. We estimated the real social value for the Finnish trawler fleet and compare that to realised value. Accounting for the positive value of the environmental externality increases the profits of the fisheries significantly. The increased profitability increased the potential resource rent and consequently the value of resources. The results show that the real social value of fisheries is considerably higher than realised.

  Citation × Citation Citation Abstract Copy Title: Bycatch Avoidance Programs in Two New England (USA) Fisheries Author: Bethoney, David, DeCelles, Greg, Stokesbury, Kevin, Cadrin, Steven, O'Keefe, Catherine, Georgianna, Daniel We conducted similar bycatch avoidance programs in two New England fisheries: yellowtail flounder bycatch in the sea scallop closed area fisheries and river herring bycatch in the Atlantic herring and mackerel fishery. These species have different behavioral properties: sea scallops are sessile; yellowtail flounder are demersal with limited but unknown range. Herring and mackerel are pelagic species with wide spatial and temporal ranges; river herring are anadromous. Management actions also differed between the two fisheries. The sea scallop closed area fisheries were limited in time and space with hard quotas for each species. The herring and mackerel fishery was limited in large scale areas by hard quotas, without quotas for river herring. Fishermen were motivated to avoid river herring by strong conservation pressure, river herring are listed as a species of concern and under review for endangered species by the U.S. agencies, which designation would effectively close the Atlantic herring fishery. In the scallop fisheries, we mapped and updated densities for target and bycatch stocks through real-time monitoring and communicated hotspots with captains at sea. In the herring and mackerel fishery we identified densities through port sampling and communicated hotspots to captains at sea. We also reported environmental factors of river herring density such as depth to captains. Percent participation exceeded 75% in each fisheries with evidence of avoidance behavior in both fisheries. Yellowtail bycatch was sharply reduced in the scallop closed area fisheries with some reduction of river herring bycatch in the herring and mackerel fisheries.
