Structural and ultrastructural description of larval development in Zungaro jahu

The Zungaro jahu is an important large catfish of the order Siluriformes that is in danger of extinction due to habitat destruction. Studies on its biology are scarce and the majority relates only to nutrition or parasitology. In order to provide greater information on its morphology and aid husband...

Studies on its biology are scarce and the majority relates only to nutrition or parasitology. In order to provide greater information on its morphology and aid husbandry and larviculture studies, the aim of this study was to characterize larval development in Z. jahu from hatching to total yolk absorption. Samples were collected at pre-established times, processed, stained, and analyzed under stereomicroscopy, light microscopy, and scanning electron microscopy. Total yolk absorption was observed by 60 hours post-hatching (hph) at 28.75 ± 0.59°C. The newly hatched larvae showed slightly pigmented body, the outline of the digestive tract, evident eyes, and the first swimming movements. Mouth opening took place at 12 hph and the connection between the oral cavity and the rudimentary intestine was observed at 24 hph. Were analyzed the main larval organs and systems: digestive organs, heart, gill arches, sensory system, thyroid, kidney, and swim bladder. As the larvae grew, these organs became more mature and functional. The development of the sensory and feeding structures was observed at the start of larval development, and thus before depletion of endogenous energy reserves, the strategy for this species is to increase its chances of survival in the environment.Companhia Energética de São PauloCentro de Aquicultura da UNESP Departamento de Morfologia e Fisiologia Animal Faculdade de Ciências Agrárias e Veterinárias (FCVA) Univesidade Estadual Paulista Julio de Mesquita Filho, Via de Acesso Professor Paulo Donato Castellani, S/NFundação Amaral CarvalhoUniversidade Federal de São CarlosUNESP's Aquaculture Center (CAUNESP) Universidade Estadual Paulista Campus JaboticabalCentro de Aquicultura da UNESP Departamento de Morfologia e Fisiologia Animal Faculdade de Ciências Agrárias e Veterinárias (FCVA) Univesidade Estadual Paulista Julio de Mesquita Filho, Via de Acesso Professor Paulo Donato Castellani, S/NUNESP's Aquaculture Center (CAUNESP) Universidade Estadual Paulista Campus JaboticabalUniversidade Estadual Paulista (Unesp)Fundação Amaral CarvalhoUniversidade Federal de São Carlos (UFSCar)2018-12-11T17:09:39Z2018-12-11T17:09:39Z2017-04-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article149-159application/pdfhttp://dx.doi.org/10.1017/S0967199416000423Zygote, v. 25, n. 2, p. 149-159, 2017.1469-87300967-1994http://hdl.handle.net/11449/17416110.1017/S09671994160004232-s2.0-850112990922-s2.0-85011299092.pdf9203413733944127Scopusreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPengZygote0,3870,387info:eu-repo/semantics/openAccessMarques, CamilaFaustino, FrancineBertolucci, BrunoDo Carmo Faria Paes, Maria [UNESP]Valentin, Fernanda Nogueira [UNESP]Nakaghi, Laura Satiko Okada [UNESP]2024-06-06T18:41:41Zoai:repositorio.unesp.br:11449/174161Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestrepositoriounesp@unesp.bropendoar:29462024-06-06T18:41:41Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false
