Abstract This study was conducted in an Amazonas state conservation unit, the Catua-Ipixuna Extractive Reserve (Catua-Ipixuna RESEX). The main purpose was to provide an ichthyological survey of its small streams, all them tributaries of the Solim6es River. Nine small streams (up to 4 m width and | m depth) were sampled in September 2006. A total of 1,525 specimens were captured, belonging to 78 species, 24 families and eight orders. Eight species had higher abundances and represented altogether 61.4 % of all collected specimens (Hemigrammus belotii, Microphilypnus amazonicus, Physopyxis ananas, Apistogramma agassizii, Elachocharax pulcher, Apistogramma cf. cruzi, Gladioglanis conquistador and Copella nigrofasciata). Based on the high number of singletons and doubletons present in our samples, as well as the estimated number of species for those streams (106 spp.), we believe that the total fish species richness present in the Catua-Ipixuna Extractive Reserve may be considerably higher than indicated by our samples. This seems especially true when considering the dimensions of the Catua-Ipixuna RESEX and the dense hydrographic network present in the area. Introduction Although not so conspicuous as the large streams may also be used as temporary refuges, rivers that dominate the landscapes in the Amazon region, the vast numbers of small forest streams constitute one of the main components of that fluvial system (Fitkau 1964; Welcomme 1985). These small water courses are hydrologically and ecologically connected to larger streams and rivers, and are a source of many essential resources (e.g. nutrients, particulate and dissolved organic matter, invertebrates) for the maintenance of the physical, chemical, ecological and biological integrity of the whole system (Vannote et al. 1980; Nadeau and Rains 2007; Wipfli et al. 2007). Low order feeding and spawning areas to migratory fish species (Meyer et al. 2007). Despite their reduced area and apparent low structural complexity, small forest streams harbor a rich fish fauna (Walker and Henderson 1996; Sabino and Zuanon 1998; Lowe-McConnell 1999; Buhrnheim and Cox-Fernandes 2003; Mendonca et al. 2005; Anjos and Zuanon 2007). However, published studies concerning the ichthyofauna of Amazon streams are still scarce and mainly concentrated to the vicinity of Manaus in central Brazilian Amazon. 154 Check List 5(2): 154-172, 2009. ISSN: 1809-127X LISTS OF SPECIES The main purpose of this study is to provide an ichthyological survey of small, 2"? and 3" order streams (according to Horton’s scale, modified by Strahler; see Petts 1994) at the Catua-Ipixuna Extractive Reserve (Catua-Ipixuna RESEX), a conservation unit in the Solimdes River basin west of Manaus. There are no studies about stream fish fauna in that area, and the information presented herein will help to increase the knowledge about fish species distribution and diversity in the Brazilian Amazon. Material and Methods The Catua-Ipixuna Extractive Reserve occupies an area of 217,486 hectares located between Tefé and Coari municipalities, state of Amazonas, Brazil (IPAAM 2003). The name of the Reserve refers to its two largest streams, Catua 64°40'0"W (03°47'13.1" S, 64°03'0.6" W) and Ipixuna (3°50'31.2" S, 63°52'22.7" W), both tributaries of the right bank of the Solim6des River (Figure 1). Nine small streams were sampled in 20 days of field work in September 2006 (dry season): four in Catua basin (Stream 1: 03°58'21.5" S, 64°20'20.8" W; Stream 2: 03°58'32.9" S, 64°21'13.3" W; Stream 3: 03°58'01.9" S, 64°20'47.2" W; Stream 4: 03°47'52.5"_ S, 64°10'31.8" W) and five in the Ipixuna basin (Stream 5: 03°52'20.3" S, 63°54'32.2" W; Stream 6 - affluent of the Marco Stream: 03°56'14.7" S, 63°56'26.1" W; Stream 7 - affluent of the Marco Stream: 03°55'48.4" S, 63°56'34.1" W; Stream 8 - affluent of the Marco Stream: 03°55'44" S, 63°56'33.7" W; Stream 9: 03°54'00"_ S, 63°56'03.4" W). 64°20'0"W 6f°o'o"w Legend » Sampled Points |_| Limts of RESEX Catua-Ipixuna Figure 1.

ISSN: 1809-127X LISTS OF SPECIES Studied streams showed mean width and depth of 2.0 m and 0.60 m respectively, and were largerly surrounded by primary forest, with substrate composed mainly by coarse litter and sand patches. Four streams are located in ferra-firme areas (upland, non floodable) and five in varzea areas (lowlands seasonally flooded by turbid water rivers). Each sample station consisted of a 50 m reach of stream. The sampling effort was standardized and based on the use of hand nets (0.4 m” area, 2 mm mesh) by two collectors during a period of 120 minutes in each stream (Mendonga et al. 2005). Fishes were preserved in 10 % buffered formalin in the field and later transferred to 70 % ethanol. Specimens were sorted and identified at the Fish Collection of the /nstituto Nacional de Pesquisas da Amazonia (INPA) in Manaus. Species were identified with the use of specific dichotomic keys and ichthyofaunal catalogues (e.g. Géry 1977; Weitzman and Géry 1980; Lucena 1987; Ploeg 1991; Buckup 1993; Mago-Leccia 1994; Buckup and Reis 1997; Retzer and Page 1997; Sousa and Rapp Py-Daniel 2005; Rommer 2006), as well as the aid of fish taxonomists of INPA, Museu de Zoologia da _ Universidade de Sdo Paulo (MZUSP), Museu de Zoologia da Universidade de Londrina (MZUEL), Laboratorio de Ictiologia da FFCL-USP-Ribeirdo Preto (LIRP), Academy of Natural Sciences of Philadelphia (ANSP), and Museu Paraense Emilio Goeldi (MPEG). Voucher specimens are deposited in the INPA Fish Collection (Table 1). Scale bars in the photos of voucher specimens represents | cm. Fish species composition was compared for the whole set of streams and for the Catua and Ipixuna basins using Jaccard’s coefficient (for presence-absence data). The coefficient values varies from 0 (completely different) to | (highly similar; Krebs 1999). A Student’s ¢ test was employed to compare the mean similarity values among streams of Catua and Ipixuna basins (Zar 1996). An overall estimate of the fish species richness in the Catua-Ipixuna RESEX was calculated by means of the Jackknife 1 method (Krebs 1999). Species richness and_ similarity values are presented as mean + standard deviation (sd). Statistical analyses were conducted using Past software (Hammer et al. 2001). Fish were collected with IBAMA authorization number 11696-2. Results and Discussion A total of 1,525 specimens were captured, belonging to 78 species, 24 families and eight orders (Appendix 1 - Table 1, Appendix 2 - Figures 2 to 78). The ichthyofauna was composed by 33 species of Characiformes (42.3 %), 17 Siluriformes (21.8 %), 14 Perciformes (17.9 %), eight Gymnotiformes (10.3 %), _ three Cyprinodontiformes (3.8 %), one Synbranchiformes (1.3 %), one Beloniformes (1.3 %) and one Myliobatiformes (1.3 %). Characiformes (830 specimens, 54.4%) was the most abundant group in the samples, followed by Perciformes (349 specimens, 22.9 %), Siluriformes (268 specimens, 17.6 %), Gymnotiformes (40 specimens, 2.6 %), Cyprinodontiformes (32 specimens, 2.1 %), Synbranchiformes (four specimens, 0.3 %), Beloniformes and Myliobatiformes (one specimen, = 0.1 % each) (Table 1). Eight species had higher abundances and represented together 61.4 % of all collected specimens: Hemigrammus belotii (Steindachner, 1882) (243 %), Microphilypnus amazonicus Myers,1927 (7.3 %), Physopyxis ananas Sousa & Rapp Py-Daniel, 2005 (5.9 %), Apistogramma — agassizii (Steindachner, 1875) (5.0 %), Elachocharax pulcher Myers, 1927 (4.9 %), Apistogramma cf. cruzi Kullander, 1986 (4.8 %), Gladioglanis conquistador Lundberg, Bornbusch & Mago- Leccia, 1991 (4.6 %) and Copella nigrofasciata (Meinken, 1952) (3.9 %) (Appendix 2, Figure 79). None of the sampled species was found in all of the investigated streams. Two species (Hemigrammus belotii and Hemigrammus ocellifer (Steindachner, 1882)) occurred in eight streams, one (Copella nigrofasciata) in seven, another one (Elachocharax pulcher) in six, and four species (Gladioglanis —conquistador, Microphilypnus) amazonicus, Microsternarchus bilineatus Fernandez-Yépez, 1968 and Rivulus 156 Check List 5(2): 154-172, 2009. ISSN: 1809-127X LISTS OF SPECIES cf. compressus Henn, 1916) were found in five streams (Table 1). Besides, 52 species (67% of the total species richness) occurred in just one or two Streams. Species richness in the samples ranged 10 - 26 (20 + 7 sd). The overall fish richness estimated for the Catua-Ipixiuna RESEX was 106 species. Overall, fish assemblage similarity values were low and ranged 0.03 - 0.35 (0.18 + 0.08 sd). There was no significant difference in mean similarity values among the streams of the Catua (0.17 + 0.01 sd, n=6) and Ipixuna (0.20 + 0.01 sd; n=10) basins (t= -5.63; p=0.582). Comparing the streams of the two basins, 22 species occurred exclusively in the Catua and 21 in the Ipixuna. Thirty five species were common to both basins. Among the fishes that occurred in just one of the sampled basins were species of the genera Gymnotus, Aequidens, Apistogramma and Nannostomus, with different species in each basin (Table 1). Studies about the composition of fish communities of small streams in Central Amazon sometimes diverge in relation to the dominance of the taxonomic groups that compose the ichthyofauna. Most studies generally point out to the dominance of Characiformes and Siluriformes (Araujo-Lima et al. 1999; Mendonga et al. 2005), although sometimes Perciformes can be _ the second in number of representatives, with approximately two times the amount of species of Siluriformes and Gymnotiformes together (e.g. Silva 1995; Buhrnheim and Cox-Fernandes 2001; Espirito-Santo et al. 2009). In the small streams of the Catua-Ipixuna Extractive Reserve, Characiformes constituted more than half of the specimens collected, mainly small midwater characins such as the ubiquitous Hemigrammus belotii. The abundance of Perciformes in our samples resulted from the large number of specimens of the minute gobiid Microphilypnus amazonicus, aS well as the dwarf cichlid Apistogramma agassizii, an also very common species in the Amazon lowlands (Kullander 1986). Fish species richness in Amazon streams is known from several studies developed in terra firme areas in Central Amazon, with numbers varying between 17 and 61 species albeit being obtained with the use of diverse sampling efforts and methodologies (Sabino and Zuanon 1998; Araujo-Lima et al. 1999; Buhrnheim and Cox-Fernandes 2001; Mendonga et al. 2005; Anjos and Zuanon 2007). As far as we know, only Henderson and Walker (1990) studied the fish fauna of a stream subjected to periodic flooding, although focusing on species associated to litter banks. The species richness found in the Catua-Ipixuna streams (78 species) may be considered high due to the small number of streams sampled (nine) in a single occasion, and to the fact that only hand nets were employed as sampling equipment. However, this high number of species may have been influenced by the close proximity and sometimes direct connection of the sampled streams to larger, main water courses of those basins. For instance, specimens of the gobiid Microphilypnus amazonicus were commonly found close to the main streams of the basins. Among the species collected there were some fishes that constitute typical inhabitants of well preserved forested streams such as Helogenes marmoratus Gunther, 1863 (Cetopsidae) and Monocirrhus polyacanthus Heckel, _——:1840 (Polycentridae). Some species were found in most of the streams sampled, such as Apistogramma spp. (Cichlidae) and Elachocharax pulcher (Crenuchidae), always associated to litter banks. Based on the high number of singletons and doubletons present in our samples, as well as the estimated number of species for those streams (106 spp.), we believe that the total fish species richness present in the Catua-Ipixuna Extractive Reserve may be considerably higher than indicated by our samples. This seems especially true when considering the dimensions of the Catua-Ipixuna RESEX and_ the — dense hydrographic network present in the area. Further efforts should be directed to the study of the ichthyofauna of the small streams of floodplain areas in the Amazon, which had been largely negleted so far. 157 Check List 5(2): 154-172, 2009.
