| early ontogeny of <i>tatia neivai</i> (ihering, 1930) (osteichthyes, auchenipteridae), a small catfish from neotropical region. | the early development of tatia neivai (ihering 1930) was analyzed (i) to characterize its morphological, morphometric and meristic development; and (ii) to examine its possible ontogenic variation as a result of the development of structures and organs necessary for survival. samples were collected in the baía river, basin paraná river, mato grosso do sul state, brazil, between february 1999 and april 2000. after identification, the specimens were separated according to notochord development, an ... | 2017 | 29245502 |
| chromosomal polymorphism in rineloricaria lanceolata günther, 1868 (loricariidae: loricariinae) of the paraguay basin (mato grosso do sul, brazil): evidence of fusions and their consequences in the population. | rineloricaria is the most species-rich genus of the loricariinae (armored catfish) with 65 valid species. however, the karyotype structure is known only for eight species in this group. this study provides cytogenetic data for rineloricaria lanceolata collected from the upper paraguay basin (mato grosso do sul). the specimens revealed extensive chromosomal polymorphism constituting 10 karyotypes, which differed in the diploid number (48 to 45 chromosomes) and fundamental number (fn) between 52 a ... | 2014 | 25069031 |
| sustainable harvest of two large predatory catfish in the cuiabá river basin, northern pantanal, brazil. | fishery is an important economic activity in the pantanal. among the regions species, the pimelodidae catfish stands out as an important part of the annual catch. this study assesses the structure, exploitation and stock management of hemisorubim platyrhynchos and sorubim cf. lima, the sixth and seventh largest pimelodidae of the pantanal. the analysis is based on fish caught by commercial fishing in the cuiabá river and landed at the "antônio moysés nadaf" market in the cuiabá city, mato grosso ... | 2007 | 17505753 |
| age and growth of the porthole shovelnose catfish (hemisorubim platyrhynchos) in the pantanal. | the porthole shovelnose catfish, hemisorubim platyrhynchos, is the sixth largest pimelodidae of the pantanal. its age and growth were studied using pectoral fin-spines from fish collected in the cuiabá river basin, pantanal. the fish, which came from commercial and experimental fisheries, were all caught with hook and line. growth-ring formation time could not be defined through the kruskal-wallis test on marginal increment (h = 4.142; p = 0.247). nevertheless, decrease in the marginal increment ... | 2004 | 15744424 |
| injuries caused by the venomous catfish pintado and cachara (pseudoplatystoma genus) in fishermen of the pantanal region in brazil. | the fishing activity throughout the upper paraguay river basin has huge financial and biological importance. this retrospective study investigated the occurrence of injuries caused by fish of the pseudoplatystoma genus (spotted catfish or pintado and striped catfish or cachara) in professional fishermen of the pantanal of mato grosso do sul state. | 2016 | 27508991 |
