In addltlon rothis etrict. aspect of selectlon of sanpllng eltes, the nl.ssion wae aleo aimed atpeifecting the knowledge already acqulred by conpleting certain faunlstic llstsfor basins still not well known. To thls end, cert,aln marginal baslns in the OCp area were sampled with 9111 ners (nesh eizes: 10-12.5, 15-17.5, 20-22.5, 25-30 and 40 nrn) and Rotenone, Ehe most I'bio-ecologica1" lchrhyotoxic available atpresent. Flnally' buE not falling dlrectly wlthln the monltorlng, some samples of fish gllls, liver and muscLes rrere taken fqr parasitological and geneEic studies to confirxn the tradltlonal taxonomy results. Only the result,s of the fishlng carried out wiEh 9111 nets will be presentedhere, giving for each Ehe data on the raw results, the catches per unl-L effort and the mean coeffieient of condition of the maln species (nunber of individuals above flve). When the nunber of individuals ls high, species length disEributton histograms will also be given. As regards gonad maturation, a summary rable of Ehe maturation stages of the princlpal species caughE ls given. We cannot glve results on the gonodosomatic ratios because we rdere unable to take a precisLon scale to the fieldl.

PERSONS WHO PARTICIPATED IN THE MISSION Reny Bigorne - ORSTOM technician Sidy Camara - Driver Moussa Coullbaly Driver Moussa Ellnane Diop - Guinean Researeher Jean-Francols Guegan - Grant-holder, Parasitology, USTL Mont.pellier Adama Kane - Fisherman Didier Paugy 0RSTOM Researcher Tiekoro Sineyogo - Fisherman 4- BRIEF DESCRIPTION OF THE STATIONS SAI'{PLED Banie aE Sanasslya: Ar this place and at that time, Ehis rributary of the Niger ffie.Deep1Eeaqu1EegreaEd1versityandconslderab1especies richness, this etatlon shouLd noE be selected because Ehere are oEher sttes already ln Gulnea on the Upper Niger. Bafing at Sokotoro: although rlch mainly in Cyprlnidae, this station appears to be a good monltorlng site because of its facleg and accessiblllty. Sala aE Markala: outslde treaEment area (t(orikoure basin). Koundlouol at Koumbia: slt.e on the Tomine, not very lnEeresElng. The stations of Gaoual on the Tomlne and Bantala on the lbumb ^2 ^r" preferable. Kogon at. Wendou Borou: station easily accessible wlEh pools easy to sample. Fatala aE Mabe: station not easily accessible and uncerEaln to reach durlng rainy season. Moreover conounity not quite rich and diversified. Site not recommended. Konkoure aE Konkoure Bridge: outside treaLmenE area. Kaba at Katiri: Ehe catching of nullets (Llza falcipinnis) proves thaE even here a marine influence is felt. This stat,ion ls therefore noE recommended. Panpana at Matotaka: despite many people collecting sand here, the waEer quallty(turbidlty) does noL seem to have been affected by it. The presence of big pools militate in favour of the selecElon of this site as nonlEoring staelon. IE is very easlly accessible (a few minutes) from Makeni by a Earred road. Sell at Magburaka: same remarks as above. Seli at Burnbuna: station interesEing but less easily accessible compared co abo"e. Pampana at Bendugu: stacion not very interesEing from t,he viewpoint of fishing as well as that of relationship with villagers (4 neEs sEolen): StaEion Eo be absoluEely proscrlbed. Bagbe at Yifin: despite a rich and diversified fauna, chis sLation cannot be selected because of the absence of water ln lE durlng the low-water period. Only a few pools of waEer of some m2 remain. Se11 at Kondembava: Etation lnterestlng ichthyologically buE difflculc to reach. Mongo at Mo0ssala: same remarks as above. 2See ORSTOM Bouake ReporEs No.35 (Dejoux and Leveque, 1989) and No.40 (Leveque and Paugy, 198I) on thls subject. 5- At the tlme Ehe conEracE was slgned, lE was agreed to conplete the flrst prospectlone made ln Guinea ln 1990. Because of the new OCP pollcy concerning the limiEing of larvlciding ln the western extension area to the upper baslns of the Nlger and to the Slerra Leone basin, we wll1 jusE recommend three sites ln Ehis country, slnce those of the Upper Niger have already been under nonltorlng since 1985. , Considerlng the flshing resulte and river accesslblllty and facies, we can, as regards Sierra Leone, reconunend two regular sampllng llltes1 i.€.; the Panpana near MaEot,aka and the Seli (Rokel) near Magbpraka. These two slEes are located a few kllonetres fron Makenl and acceeslble in a few minutes by a tarred road. A Ehlrd site situated on Ehe Mongo, near Moussala, Beems Eo be very interest,ing faunlstical.ly but not easlly accessible fron Makenl (Slerra Leone) or Faranah(Guinea). Slnce E,he Rot,enone flshing results take a long t,ine to process, Ehe detalls of these samples will be presenEed ln a subsequent report.
