“…Just fertilized embryos (0 HPF) showed an average diameter 3.43 ± 0.11 mm for animal-vegetal axis. Developmental patterns observed in this study were, in overall, accordant with previous descriptions (Dettlaff et al 1993;Park et al 2013b), although the onsets and transitions of a particular stage did not exactly match the time points reported in previous works, probably mainly due to the difference in incubation temperatures. Under the present incubation conditions, uneven holoblastic cleavages comprising of irregular blastomeres continued until 10 HPH (Dettlaff et al 1993).…”

“…Sampled embryos were fixed in cold 4% paraformaldehyde. Outer jelly coats of embryos were removed with fine forceps and subjected to microscopic examination in order to determine the developmental stages and also to scrutinize morphological features of the embryos (Park et al 2013b). Image analysis was made with the NIS-Elements BR image analysis software implemented in the AZ100 microscope (Nikon, Tokyo, Japan).…”

Background: Russian sturgeon (Acipenser gueldenstaedtii) is an emerging candidate species in the Korean aquaculture domain owing to its highly valued caviar. Although the embryonic development of this species was previously described, the complete image data on the morphological differentiation of developing embryos have not been yet fully available. Further, with the viewpoint of larval production in hatchery, the effects of temperature on embryonic viability and the temporal window of hatching event have not been extensively studied. Hence, the objective of this study was to provide a complete set of photographic image data on the embryogenesis and also to examine the effects of incubation temperatures on embryonic viability and hatching event in farm-bred Russian sturgeon. Results: Typical characteristics of embryonic development including uneven, holoblastic cleavages with unequal blastomeres, followed by the formation of germ layer, neurulation, and organogenesis until hatching, were documented. Under different temperature conditions (12, 16, or 20°C), viability of embryos incubated at 12°C was significantly lower as relative to those of 16 and 20°C incubated embryos. Hatchability of embryos was higher, and the timing of hatching event was more synchronized at 20°C than at 12 and 16°C. Conclusion: Data from this study suggest that the incubation of Russian sturgeon embryos at 20°C would be desirable in the hatchery practice with respect to the good hatchability of embryos and the synchronization of hatching events. Additionally, the updated image data for complete embryonic development could be a useful reference guide for not only developmental researches but also artificial propagation of Russian sturgeon in farms.

“…For each temperature group, the time to reach various developmental stages (blastulation, gastrulation, small yolk plug formation, late neurulation, s-heart formation, and the first occurrence of hatching) was monitored. Descriptions of each developmental stage in this species referred to Park et al (2013). During each of the four selected stages, the survival rate (percentage) was also estimated for each egg batch.…”

Early ontogenic development in Siberian sturgeon Acipenser baerii was documented and the effects of different temperatures on embryonic and prelarval development were examined. Photograph-assisted data on morphogenesis in Siberian sturgeon prolarvae agreed well with published descriptions of their ontogeny and ecological behaviors, although certain aspects of differentiation, such as gill covering and scute development, could be rearing condition-sensitive. The present study provides the first characterization of the transient development of teeth during early larval stages; the pattern was congruent with the transition of prolarvae to exogenous feeding. From examinations of embryonic and prelarval development under different temperature conditions (12-24°C), developmental speed was inversely related with temperature. Overall, hatchability was higher and hatching events were more synchronized at 20°C than at lower temperatures. After hatching, similar patterns of temperature-dependency were observed in yolk sac absorption and the evacuation of the pigment plug. Our results suggest that the incubation of Siberian sturgeon embryos and prolarvae at temperatures close to 20°C would be advantageous in hatcheries, based on reductions in the duration and uniformity of egg and prolarval developmental stages.

“…Acipenser baerii and A. gueldenstaedtii are reared and raised in hatcheries in Europe for caviar and food production (Bronzi, Rosenthal, Arlati, & Williot, ; Williot et al, ). This has augmented interest in several aspects of their natural history, not only related to hatchery and rearing questions (Gisbert & Ruban, ; Psenicka et al, ; Zelazowska, ) but also regarding their development (Gisbert, ; Rodríguez & Gisbert, ; Song & Song, ), including staging tables and descriptions of embryonic and larval stages (Leprévost, Azaïs, Trichet & Sire, ; Ginsburg & Dettlaff, ; Park, Lee Sang, Kim, & Kwon, ; Schmalhausen, ). As a contribution to the study of the vertebrate skull and to provide information that will help to solve the evolutionary relationships among the species, we document the skeletal development of the skull and the pectoral girdle of A. baerii and A. gueldenstaedtii , and provide an overview of the developmental timing of the differentiation of skeletal elements.…”

The head is considered the major novelty of the vertebrates and directly linked to their evolutionary success. Its form and development as well as its function, for example in feeding, is of major interest for evolutionary biologists. In this study, we describe the skeletal development of the cranium and pectoral girdle in Siberian (Acipenser baerii) and Russian sturgeon (A. gueldenstaedtii), two species that are commonly farmed in aquaculture and increasingly important in developmental studies. This study comprises the development of the neuro-, viscero- and dermatocranium and the dermal and chondral components of the pectoral girdle, from first condensation of chondrocytes in prehatchlings to the early juvenile stage and reveals a clear pattern in formation. The otic capsules, the parachordal cartilages, and the trabeculae cranii are the first centers of chondrification, at 8.4mm TL. These are followed by the mandibular, then the hyoid, and later the branchial arches. Teeth form early on the dentary, dermopalatine, and palatopterygoid, and then appear later in the buccal cavity as dorsal and ventral toothplates. With ongoing chondrification in the neurocranium a capsule around the brain and a strong rostrum are formed. Dermal ossifications start to form before closure of the dorsal neurocranial fenestrae. Perichondral ossification of cartilage bones occurs much later in ontogeny. Our results contribute data bearing on the homology of elements such as the lateral rostral canal bone that we regard homologous to the antorbital of other actinopterygians based on its sequence of formation, position and form. We further raise doubts on the homology of the posterior ceratobranchial among Actinopteri based on the formation of the hyoid arch elements. We also investigate the basibranchials and the closely associated unidentified gill-arch elements and show that they are not homologous. J. Morphol. 278:418-442, 2017. © 2017 Wiley Periodicals, Inc.
