Campaign: Fishes of Oroklini Lake, Cyprus

March 1st 2013 

With Cypriot friends Athena and Iakovos and guided by Melpo Apostolidou from BirdLife Cyprus we explored Oroklini Lake. It is a soon-to-be famous wetland area located near Larnaka. This was our first ever wet-season ichthyological sampling here using a fry-net seine (everybody should have a fry-net with them anywhere they go...). Water levels were surprisingly high and the water that entered the lake from the upstream riverlet smelled rather bad. However the first site we sampled (near "The Sluice") is full of invert life - but no fish. The lake has a huge population of Gambusia Mosquito Fish but they are probably widely dispersed all around at this time (densities are low at high-water levels during winter here). Near the main "East Canal" outflow by the beach we tried in vain to catch elvers (young eels) - no luck. We did spot some rather large grey-mullets (but we need a fish-trap to catch those...). We did catch Mosquito Fish here and then again more at the second canal ("West Canal"). No eels this time; but, the birding was fantastic. It was a great afternoon out. 

For more info on the restoration and conservation work being done at Oroklini please see:

Melpo Apostolidou works at one of the most important NGOs for nature conservation on Cyprus BirdLife Cyprus - a group all Cyprus-lovers should support! Have a look at their new site:

No life- could someone have poisoned the water? 
West Canal with reedbed - great Eel habitat.

Chest-waders are not enough!
