Future out l ook From an economlc slandpoi.nt, AMCF Ls at a c!ossroads ' Although adrninistered by Ewco, Ewco is severely constrained in its charge in that it derives no revenues fron the management of AMCF ' Profits are returned to the central national treasury ' thus
153 depriving EWCO of incentive for sound fiscal, husbandry, or labor management, Funds and manpower trom EJCo are sometimes dj.verted from other areas of responsibilj.ty to keep the project operational. AIiCF would almost assuredly be better rnanaged by a private concern or corporation that would provlde a rnore predictable operational cash flon and the professional expertise needed to guide labor and connnercial husbandry. Such a recomnendation in the past night have been contrary to the previous political interests, However, prospects might perhaps be better nolr for such a conversron srnce the installation of the Transitional Government of Ethropra. In terrns of crocodile conservation. AMCF has had a negligible j.mpact. Restocking of hatchlings to the wj.ld has occurred only when space \"ras unavailable to house them within AMCF. Some benefit to crocodj.le nests against depredation was afforded during previous years r.rhen surveys were conducted and nests gr.rarded and monitored for egg collection (Hailu, 1990), Hor,rever, this practice is now discoDtinued and no surveys of wild crocodile populations have been made slnce 1987. Trophy hunti.ng tor crocodiles is still of no irnportance i{ithin Ethiopia and wiIl probably remain so for the near future. The monitoEj.ng of crocodile curios is problenatical at best. While the quota for Ethiopia is very snall, the trade in curios (and other wildlife products) remains in the effective hands of the taxidertny industry for whj-ch there is no control at present. Protected and endangered wiLdlife species are regu).arly sold in Addis Ababa shops having been "certified" as legal by local
