herefishiefishie Posted December 30, 2003 Report Share Posted December 30, 2003 add population growth, destruction of forests, land used for agricultural farming,eg; the delta system of the Ruzizi river (supplies 50% of salt depoists to the lake) has had a tenfold increase of sedimentation over the last 2 decades. Several species of fish & vertbrates have vanished. Surely murky water would effect algae growth too. The BBC, temp increase of 1.5 degrees is more like 0.6 degrees increase & its over a 80 year period. Results also showed that the upper levels of the lake were still very high/saturation oxygen levels. So if the cichlids of tangy have been around for so many years could they evolve/ adapt again. :-? pollution will kill them first or will it 8) As for commerical fishing they started commerical fishing in 1954, they still take out 120,000 - 200,000 tonnes of fish a year.1983- Plus a question, 8) How come cichlids in tangy can co-exist(so far) with the nile perch??4 known species in the lake. Will we get a boom attack like in lake Victoria, at least there now the perch have turned to cannaballism. Frenchy :roll: Quote Link to comment Share on other sites More sharing options...
