“…Hatching period of M. fluviatilis was between 7 and 9 days, whereas of M. s. splendidia, between 4 and 8 days of embryonic development. Arenzon et al (2002), mentioned that M. s. australis, M. s. inornata and M. niigrans (Melanotaenia genus species), presented embryonic period of 4.5 days at 26°C (Humphrey et al, 2003). Larvae hatched through corium rupture in a very fast way, similar to the observed by Ferreira et al (2009) to the…”

“…Hisaoka & Firlit (1960) reported that, in zebrafish, the mitotic divisions are synchronous until 32 cells but become asynchronous at 64 cells. Arezon et al (2002) reported that embryos of Cynolebias melanotaenia develop faster at 25…”

SummaryThis survey was performed to characterize the embryogenesis of Prochilodus lineatus. Seven stages of embryo development were identified -zygote, cleavage, blastula, gastrula, segmentation, larval and hatching -after a period of incubation of 22 h (24• C) or 14 h (28 • C). The following cleavage pattern was identified: the first plane was vertical (2 blastomeres); the second was vertical and perpendicular to the first (4 blastomeres); the third was vertical and parallel to the first (4 × 2); the fourth cleavage was vertical and parallel to the second (4 × 4); the fifth was vertical and parallel to the first (4 × 8); and the sixth cleavage was horizontal (64 blastomeres • C); 11.0-13.0 h (28 • C)) showed a free tail, more than 25 somites, an optic vesicle and a ready-to-hatch larval shape. The blastomeres at cleavage stage had disorganized nuclei indicating high mitotic activity. At gastrula, the blastomeres and the periblast had euchromatic nuclei and a large number of mitochondria and vesicles. The yolk was organized into globose sacs, which were dispersed into small pieces prior to absorption.

“…However, the resting eggs remain on diapause, waiting the next rainy season, when they will hatch and start a new life cycle (Podrabsky & Hand 1999). Annual fish have been used as model organisms for laboratory (Arenzon et al 2002a(Arenzon et al , 2003, bioindicators (Arezo et al 2007), pest control (Fletcher et al 1992, Frenkel & Goren 2000 and ornamental fish (Costa 2008).…”

“…Temperature has been shown to influence Rivulidae fish in terms of reproduction (Arenzon et al 1999), time of the embryonic development (Arezo et al 2007, Arenzon et al 2002a), growth (Errea & Danulat 2001, Walford & Liu 1965, Liu & Walford 1970, and longevity (Walford & Liu 1965, Liu & Walford 1966, 1970.…”

Effect of temperature on growth of the threatened annual fish Austrolebias nigrofasciatus Costa & Cheffe 2001

This study evaluated the effect of temperature on growth of Austrolebias nigrofasciatus, an endemic and threatened annual killifish species of the Patos-Mirim lagoon system in Southern Brazil. In order to verify the effect of temperature on initial growth of A. nigrofasciatus, eggs stored in the laboratory were hatched and juveniles reared for eight weeks at 16 and 22 ºC. The standard length of newly hatched fishes was 4.67 ± 0.25 mm and after eight weeks they reached 23.68 ± 3.73 and 22.68 ± 5.36 mm, respectively at 16 and 22 ºC. However, initial growth of fish reared at 22 ºC was faster and they reached sexual dimorphism at an earlier age compared to those reared at 16 ºC. Final length of females reared at 22 ºC was 23.00 ± 2.83 mm, they were significantly larger than those reared at 16 ºC (17.91 ± 2.47 mm). Males were significantly larger than the females at 16 ºC, but there was no difference for growth between sexes of fish reared at 22 ºC. The sex ratios were 1:0.6 and 1:1.1 (M:F) at 16 ºC and 22 ºC, respectively, suggesting temperature determination of phenotypic sex. Considering the results, it appears that juveniles to be developed in captivity should be kept at 22 ºC during the first six weeks of life, thus ensuring a higher growth rate until puberty.
