| observations on cucullanid nematodes from freshwater fishes in mexico, including dichelyne mexicanus sp. n. | a new cucullanid nematode, dichelyne mexicanus sp. n., is described from the intestine of three species of fishes, agonostomus monticola (bancroft) (mugilidae, perciformes) (type host), ictalurus balsanus (jordan et snyder) (ictaluridae, siluriformes) and cichlasoma beani (jordan) (cichlidae, perciformes), from three rivers (la maquina river, veracruz; chontalcoatlán river, guerrero and santiago river, nayarit) in central mexico. this species is characterised by the absence of a ventral sucker i ... | 1999 | 10730201 |

| [helminths from the fish dormitator maculatus (osteichthyes: eleotridae) from alvarado, veracruz, mexico]. | dormirator maculatus (n=184) was collected in the alvarado lagoon, mexico during a year period (oct. 1993-1994). in the helminthologic review, the presence of clinostomum complanatum (82.3%), neoechinorhynchus golvani (76.1%), spiroxys sp. (21.3 %), and camallanus sp. (6.2%) was registered. reduction of the hematocrit caused by such infection is significant (t, a= 0.05). | 2004 | 17354390 |
| morphological and molecular data reveal a new species of neoechinorhynchus (acanthocephala: neoechinorhynchidae) from dormitator maculatus in the gulf of mexico. | neoechinorhynchus (neoechinorhynchus) mexicoensis sp. n. is described from the intestine of dormitator maculatus (bloch 1792) collected in 5 coastal localities from the gulf of mexico. the new species is mainly distinguished from the other 33 described species of neoechinorhynchus from the americas associated with freshwater, marine and brackish fishes by having smaller middle and posterior hooks and possessing a small proboscis with three rows of six hooks each, apical hooks longer than other h ... | 2014 | 25064596 |
| spatial distribution and seasonality of ichthyoplankton and anthropogenic debris in a river delta in the caribbean sea. | temporal changes in larval fish species composition and abundance compared with other components of the seston are described in four estuarine habitats in the atrato delta, colombia. in comparison with zooplankton, fish larvae and egg density and anthropogenic debris abundance were low in the south atrato delta. transparency, water temperature and chlorophyll a were the major factors influencing the spatiotemporal distribution of ichthyoplankton in the delta. the most abundant fish larvae were a ... | 2017 | 28138987 |
| morphological and molecular analyses of a new species of saccocoelioides szidat, 1954 (haploporidae nicoll, 1914) in the fat sleeper dormitator maculatus (bloch) (perciformes: eleotridae) from the gulf of mexico. | saccocoelioides olmecae n. sp. is described from specimens recovered from the intestine of the fat sleeper dormitator maculatus (bloch) (perciformes: eleotridae) collected in six localities along the coast of the gulf of mexico. the new species is mainly distinguished from the other three described species of saccocoelioides szidat, 1954 from north and middle america (i.e. s. sogandaresi lumsden, 1963, s. chauhani lamothe-argumedo, 1974 and s. lamothei aguirre-macedo & violante-gonzález, 2008) b ... | 2016 | 27456273 |
