ABSTRACT 
In the ichthyological research carried out from 1981 to 1993, Iwenty-two taxa (species, subspecies) and one hybrid (Salmo trutta m. fario x S. marmoratus) from 10 families (Siluridae, Anguillidae, Esocidae, Salmonidae, Cyprinidae, Cyprinodontidae, Poecilidae, Gaslerosteidae, Cottidae, Gobiidae) were recorded in fresh waters of the Istrian Peninsula. Twelve of them were native, and SO introduced. Results differ in comparison with literature data, in which 27 taxa and one hybrid from 7 7 families were listed, as well as one lamprey species (Petromyzontidae). We failed to repeat the records of five species listed in the literature, i.e. Barbus barbus, B. meridionalis, B. caninus, Leuciscus cephalus, and L. leuciscus. The mentioned data were related to Barbus plebejus, and Leuciscus cephalus albus and L. svallize respectively. The taxa Gobio gobio obtusirostris, Knipowitschia panizzai, Leuciscus svallize, Carasius auratus auratus, and Carassius auratus gibelio represent the first records for Istrian waters. For the first time, Alburnus albidus alborelh was caught in the Mima river and in Butoniga reservoir. Old data were related exclusively to Lake Čepic, drained out in 1932/33. The presence of Leuciscus svallize in Istrian waters is the most northernmost record of its occurrence in the Adriatic Basin. The present study has expanded the distribution data on Phoxinus phoxinus, Rutilus rubilio, and Gambusia affinis in Istrian waters. The northernmost occurrence of Rutilus rubilio in Croatia was registered in the Boljunč ica stream and the Raša river.

INTRODUCTIO N 

The fish fauna of the istrian Peninsula (the Adriatic catchment area) has not been systematically investigated in the past. The first data about Istrian freshwater fish from the second half of the 19th century to the beginning of the 20th century were published by Italian authors (Largaiolli 1904, Marchesetti 1920, Parenzan 1929, Cridelli 1936). 
The data published after the Second World War were scarce, cited localities were not precise (Taler 1953, Tortonese 1970, 2tki<i & BertoSa 1980, tikiC et al. 1982). 

STUD Y AREA 

The results of our research carried out from 1981 to 1993, were based on investigations of 23 sites located on Croatian streams watercourses (the Mima, the Bracan, the Boljundca, the Butoniga, the Fojba

MATERIAL AN D METHODS 

Fish were captured by electrofishing. Sampled stream sections were blocked at the upper and lower ends with 6-mm seines. Reservoirs, lakes and ponds were sampled by electrofishing too along the banks as well as by ordinary fishing gear and 30 m long floating nets. Captured fish were identified and then released. Some specimens were kept for further analysis. The material was stored in the Croatian Natural History, Museum, the Centre, for Fisheries in Zagreb and the Fisheries Research Institute in Ljubljana. 
New data collected in 1981-1993 period, were numbered and numbers correspond to the localities recorded in figure 1. Systematic arrangement and taxo­nomy follow Banarescu (1971), Hureau and Monod (1973) and Lelek (1987).

Comparisons of the literature data with our study indicate many discrepancies. Of the 35 species (and subspecies) recorded in literature and registered in our ichthyological research, eleven allochthonous species were registered; one of them, C. carassius, was mentioned only in literature. In the research, carried out from 1981 to 1993, 22 species and subspecies as well as 1 hybrid from 10 families were established; 12 species were confirmed as native and 10 as introduced. In literature, 27 species (eleven introduced), 1 hybrid, and 1 lamprey are stated for the same area. 
The pike Esox lucius occurs in Rakov Potok reservoir (Pazin Angler Society - personal communication), al­though we did not catch any specimen. 
The carp Cyprinus carpio is common and abundant in many Istrian waters. Although the carp was reported to be present in istrian waters already at the beginning of the century, the statement of Žikič ef al. (1982) that the carp is a native fish species in Istria is not acceptable. 
Barbus plebejus is native to the Adriatic Basin and we assumed that the data concerning 8. barbus by Žikič ef a/, (1982) were related to B. plebejus. It is present in most of the istrian streams, as well as in Butoniga reservoir, while for B. cartinus and B. m. petenyi we did not obtain any data. 
We have not information about C. a. gibelio being introduced to istrian waters. 
Concerning the genus Leuciscus in istria, Žikič & Bertoša (1980) and Žikič ef al. (1982) stated that L. cephaius and L leuciscus were native to these waters. These species are native to the Danue River basin. We suppose that the mentioned data were related to L. c. aIbus and L. svailize, although Bianco (1987) states that 
L. c. albus lives in central Italy only. 
We agree with C ridel i i (1936) that reports on L. c.. cabeda from the Mirna and Fojba rivers referred to the subspecies albus. 
The tench Tinea tinea, introduced to the carp fish farms around the Lake Čepic at the beginning of the 20th century, is now abundant in reservoirs and in streams. 
The present study has expanded the distribution data of P. phoxinus, ft. rubiiio, and G. afiinis in Istrian waters. The northernmost occurrence of R. rubiiio in Croatia was registered in the Soljunčica stream and the Raša river. 
forty years ago, Gambusia afiinis was a common species in the waters around Koper, but I and-recla­mation activities led to its almost complete disap­pearances (Porečnik 1958a). 
Bonaparte (1832-1841) and Karaman (1928) reported on the presence of Scardinius erytbrophthalmus and Cobitis taenia in this area, but we did not confirm these data. 
Gasterosteus aculeatus used to be widely distributed in Istrian waters. Today its presence was confirmed only in the Rižana river. 
Information by Porečnik (1958b) about Gobius fluviatilis living in the Rižana river, and lamprey species Lethenteron zanandreai in the waters around Koper were not confirmed during this research. 
The taxa Gobio g. obtusirostris, K. panizzai, L. svailize, C. a. auratus, and C. a. gibelio represent the first record of occurence for Istrian waters. The presence of Leuciscus svailize caught for the first time in fresh waters of Istria in the years 1983-1984, is northernmost record of its occurrence in the Adriatic Basin (Leiner 1983, Leiner & Popovič 1984). 
The presence of allochthonous species Gobio g. obtusirostris was recorded for the first time in 1984. 
For the very first we caught Albumus albidus alborella in the Mirna river and in the Butoniga reservoir. Old data are related exclusively to the Lake Čepic, drained out in 1932/3.3. 
We did not find any old or new data on the presence of sturgeons (Acipenseridae), and Petromyzon marinus occurred in the Adriatic Basin, in the waters of the Istrian Peninsula.

POVZETEK 
V obdobju 1981-1993 so potekale ihtiološke raziskave o razširjenosti sladkovodnih rib istrskega polotoka. Popisanih je bilo 22 vrst in podvrst iz 10 družin in 1 križanec Saimo trutta m. fario x S. marmoratus. Dvanajst vrst je avtohtonih in 10 naseljenih. Ti podatki se bistveno razlikujejo od literaturnih, ki navajajo, da živi na istrskem polotoku 27 vrst in 1 križanec iz 11 družin ter ena vrsta piškurja.
