Broodstock management: cryopreservation parameters to select native tropical fish. Author(s): MATAVELI, M.; ALVES, A. L.; KIRSCHNIK, L. N. G.; MORO, G. V.; VARELA, E. S. Genetic management of broodstock aims to produce fingerlings of superior quality from the adoption of practices and technological processes that assist in the control of the breeders. For this effecti... ... Repository: BDPA Publication year: 2015
Mass synchronization of gonadal maturation in banded knifefish broodstock (Gymnotus cf. carapo) Author(s): ROTTA, M. A.; RODRIGUES, R. B.; PEDROSO, M. F.; ACORCI FILHO, L. C.; LARA, J. A. F. de; STREIT, D. P. Abstract: The banded knifefish Gymnotus cf. carapo (Pisces, Gymnotidae), also known locally as tuvira, is a natural resource of great importance to the Pantanal biome that has been used as live bait i... ...

Impacts of stocking on the genetic diversity of Colossoma macropomum in central Amazon, Brazil. Author(s): QUEIROZ, C. A. de; SOUSA, N. R.; SILVA, G. F. da; INOUE, L. A. K. A. Tambaqui (Colossoma macropomum) is the main fish species farmed on a commercial scale in northern Brazil. In view of the current scenario of Brazilian aquaculture, studies on the genetic improvement a... ... Repository: BDPA Publication year: 2016
First record of an in vivo collection of semen from pirarucu Arapaima gigas (Schinz, 1822). Author(s): TORATI, L. S.; LOPES, J. T.; LIMA, A. F.; KIRSCHNIK, L. N. G. In this study we report novel information on the opening position of the spermatic duct of Arapaima gigas, and method to collect semen in live broodstocks. Repository: BDPA Publication year: 2022
SNP discovery in three South American freshwater characiformes species by deep sequencing of Reduced Representation Libraries (RRL). Author(s): IANELLA, P.; VARELA, E. S.; VILLELA, L. C. V.; YAMAGISHI, M. E. B.; OLIVEIRA, F. S. de; PAIVA, S. R.; CAETANO, A. R. This represents the first report of a large-scale effort to identify SNP markers for Pacu and Pirapitinga species, useful for prospecting species-specific SNPs for species-purity certification of comm... ...

Genetic variability of marine shrimp in the brazilian industry. Author(s): MAGGIONI, R.; COIMBRA, M. R. M.; COSTA, R. B. da; DINIZ, F. M.; MOLINA, W. F.; OLIVEIRA, D. M. de; LEGAT, A. P. The objective of this work was to estimate the genetic variability level and distribution in Brazilian broodstocks of marine shrimp (Litopenaeus vannamei). Nine of the country?s largest hatcheries wer... ... Repository: BDPA Publication year: 2013
The spermatozoa ultrastructure of the giant Amazon pirarucu Arapaima gigas (Schinz, 1822). Author(s): KIRSCHNIK, L. N. G.; LOPES, J. T.; LIMA, A. F.; TORATI, L. S. In this study we provide a first complete ultrastructure description of the spermatozoa from pirarucu A. gigas collected in vivo. To do so, adult male broodstocks of A. gigas held at Embrapa Fisheries... ... Repository: BDPA Publication year: 2022
Advances into the captive reproduction of the amazon pirarucu (Osteoglossidae: Arapaima). Author(s): TORATI, L. S.; LIMA, A. F.; MESQUITA, P. E. C.; TAGGART, J. B.; ALBALAT, A.; TAYLOR, J.; MIGAUD, H. This communication will present preliminary findings on the development of tools to improve captive reproduction of A. gigas. A method for ovary inspection through gonoductoscopy was developed to over... ... Repository: BDPA Publication year: 2015
Effects of GnRHa slow-release implants in the steroid profile of isolated couples of Arapaima gigas (Schinz, 1822). Author(s): TORATI, L.; TAYLOR, J.; MESQUITA, P.; MIGAUD, H. The aim of the study were 1) to induce spawning of isolated broodstock pairs with GnRHa slow-release implant technique (Zohar and Mylonas, 2001) and monitor steroid levels in blood plasma; and 2) char... ... Repository: BDPA Publication year: 2016
The influence of sex ratio on the reproduction of pirarucu, Arapaima gigas, in captivity. Author(s): LIMA, A. F. Because sex ratio in the broodstock can influence the reproductive behaviour of a species, the influence of sex ratio on the reproductive success of pirarucu, Arapaima gigas, in captivity was assessed... ...
