Summary of information relating to impacts of sea lice from fish farms on Scottish sea trout and salmon

Sea lice infest both farmed and wild salmonids to the potential detriment of aquaculture and angling interests. Several reviews have recently considered information concerning interactions between salmon farms and wild salmonids (e.g. Revie et al. 2009; Costello 2009; Whelan, 2010). Here, the evidence available to assess the likelihood and scale of impact of sea lice from salmon farms on Scotti...

Trends during development of Scottish salmon farming: An example of sustainable intensification?

Commercial farming of Atlantic salmon in Scotland started in 1969 and has since expanded to produce >179,000 t yr. A government department has published annual statistics and information on the seawater and freshwater sub-sectors of the Scottish salmon farming industry since 1979, and this review collates and discusses metrics covering aspects of production, farm sites and systems, fish perform...

Investigating the Effect of Palangan fish Farms on Water Quality of Sirvan River Using Physicochemical and Biological Indicators

The effect of Palangan fish farms on water quality of Sirvan River was investigated using physicochemical and biological indicators from January 2015 to June 2015. Five stations were determined including 1) before the fish farm 2) after the fish farm effluent 3) sub-branch 4) 100 meter after fish farm effluent and 5) 1000 meters after fish farm effluent. EC showed significant differences in dif...

Seasonal influence on the hematological parameters in cultured Nile tilapia from southern Brazil.

This study evaluated seasonality in hematological parameters of Nile tilapia cultured in the state of Santa Catarina, southern Brazil. A total of 240 fish were examined during four seasons between April 2007 and March 2008 in three different fish farms. After being anesthetised in a benzocaine solution, blood samples were withdrawn into syringes containing a drop of 10% EDTA for hematological a...
