“…The stages observed through the embryonic development of the species analysed in this study (zygote, cleavage, gastrula, organogenesis and hatching) are similar to those reported in P. corruscans × P. reticulatum hybrids (Faustino et al, 2007;Shadrim & Emel'yanova, 2007), P. corruscans (Marques et al, 2008) and Zungaro jahu (Nogueira et al, 2012). The only exception is the blastula stage, described by these authors but not found in the present study, because blastocele formation was not observed in L. marmoratus embryogenesis.…”

“…In bony fishes, fat droplets may be present in the yolk mass in distinct number and size according to each fish family, as reported in the freshwater B. cephalus (Lopes et al , 1995) and marine Abudefduf sexfasciatus (Shadrim & Emel’yanova, 2007). However, no fat droplets were detectable in the yolk of L. marmoratus , following the pattern observed in Prochilodus lineatus (Ninhaus-Silveira et al , 2006), B. orbignyanus (Ganeco et al , 2008) and B. insignis (Andrade-Talmelli et al , 2001).…”

Embryological studies in fish species are useful to the understanding of their biology and systematics. The available biological data in Leiarius marmoratus are scarce and additional information about its reproductive biology is needed, mainly because this species has been commercially exploited and used in production of hybrid lineages. In order to evaluate the temporal-morphological embryonic modifications in L. marmoratus, samples of nearly 200 embryos were collected at random at different stages of development, starting from fecundation (time zero). Embryos were fixed in modified Karnovsk's solution and 2.5% glutaraldehyde, processed and analysed under optic and electron microscopy. The incubation period of L. marmoratus was equal to 14.42 h at a mean temperature of 28.3 ± 0.07°C. The following stages of embryonic development were established: zygote, cleavage, gastrula, organogenesis and hatching. These stages were divided into phases, as follows: cleavage - phases of 2, 4, 8, 16, 32 and 64 cells and morula; gastrula - phases of 25, 50, 75 and 90% of epiboly and blastopore closure; and organogenesis - neurula, segmentation and pre-larval phases. The embryogenesis of L. marmoratus was typical of neotropical teleosteans, with peculiarities in species development.

“…Comparative data on spawning patterns of other damselfishes are available since there are many studies on diel and lunar spawning patterns, as well as clutch loss due to filial cannibalism (see [30]). Comparative data on embryo development in two other Abudefduf species have also been reported [31,32].…”

“…Samples from all new clutches were examined for developmental defects within a few hours of collection. Normal and abnormal development was determined by observation and comparison with diagrams, photographs and descriptions from the literature [31,32,40,[58][59][60]. Since development within a clutch is synchronous, an embryo was considered defective if its developmental stage was grossly different from the developmental stage of other embryos in the sample or if there was no morphological differentiation observed in the embryo.…”

This study investigated the association between sediment contamination, PCB accumulation in adult nesting males and the occurrence of embryonic abnormalities in the damselfish, Abudefduf sordidus, from two sites with high PCB contamination and three “reference” sites (contaminants very low or not measurable) within Johnston Atoll, Central Pacific Ocean. Developmental abnormalities were assessed in damselfish embryos collected in the field during four natural spawning seasons (1996, 1998, 1999, and 2001). Laboratory incubations of abnormal embryos demonstrated that the observed abnormalities were lethal. PCBs were measured in fish collected in three years. Mean whole-body concentrations of total PCBs ranged from 364.6 to 138,032.5 ng/g lipid. A significant residue–effect relationship was found between total PCB concentration and embryo abnormalities. The occurrence of embryo abnormalities was positively related to fish PCB concentration (other contaminants were also evaluated including metals and dioxins). This study demonstrates the utility of using damselfish embryos as a bioindicator tool for monitoring coral reefs. It also provides baseline-monitoring criteria and evaluates sediment quality benchmarks used for ecological risk assessments on coral reefs.

“…Comparison of egg and hatchling traits across Pomacentridae reveals linked patterns. For example, ellipsoid eggs have a single oil droplet and produce relatively less-developed hatchlings (Alshuth et al, 1998;Emel'yanova et al, 2009;Fujita, 1957;Jin Koo et al, 2001;Kingsford, 1985;Moser, 1996;Shadrin & Emel'yanova, 2007), whereas capsular eggs have either single or multiple oil droplets and all three levels of hatchlings development, depending on the species (Brinley, 1939;Dhaneesh et al, 2009;Dhaneesh et al, 2012;Ghosh et al, 2012;Kavanagh, 2000;Krishna et al, 2016;Kumar et al, 2010;Olivotto et al, 2003;Rattanayuvakorn et al, 2005;Roy et al, 2014;Setu & Ajith Kumar, 2010;Shabana & Helal, 2006;Sreeraj, 2002;Uthayasiva et al, 2014;Yuan-Shing et al, 2007). Also, segregation of early developmental traits according to different thermal ranges indicates that species with elliptical eggs occur at all temperature ranges (12-28 C), whereas species with capsular eggs are limited to warmer habitats (21-28 C; Allen, 1991).…”

Embryonic development and larval morphology of Chromis crusma was described from five nests sampled between 21 and 25 m depth in central Chile (33°S). From each nest, a set of c. 100 randomly selected eggs were hand‐collected and transported in seawater to the laboratory. Subsets of c. 30 eggs per nest were maintained in 50 ml glass containers at a constant ambient temperature of c. 12°C (range 11.5–12.9°C). Egg length (L) and width (W) and larval notochordal length (LN) were measured from photographs. Geometric morphometric analyses were performed in newly hatched and 1 week old larvae to quantify shape changes. Ellipsoid eggs had an average (mean ± SE) size of 1.12 ± 0.05 mm L and 0.67 ± 0.02 mm W, with volume being similar throughout 15 developmental stages (i.e., ellipsoid‐shaped; 0.27 mm3). Planktonic larvae hatched between 5 and 11 days at 12°C and had a mean LN of 3.13 ± 0.25 mm, a yolk sack volume of 0.03 mm3 and an oil droplet volume of 0.005 mm3. Morphological traits at hatching included: (a) lack of paired fins and jaws; (b) single medial fin fold; (c) lack of eye pigmentation; (d) yolk sac present near anterior tip; (e) melanophores distributed along ventral surface with one pair over the forehead. In order to generate an up‐to‐date summary of developmental traits within Pomacentridae, we reviewed literature on egg development (e.g., shape and number of oil droplets), hatching and larval traits (e.g., morphology, pigmentation patterns). Thirty‐two publications accounting for 35 species were selected, where eggs, embryonic development, hatching and larval traits were found for 26, 21, 24 and 34 species, respectively. In order to evaluate potential phylogenetic and environmental relationships within the early stages of Pomacentridae, cluster analyses (Bray Curtis similarity, group average) were also performed on egg and larval traits of 22 species divided by subfamily (Stegastinae, Chrominae, Abudefdufinae, Pomacentrinae) and thermal ranges (i.e., low: 16.5°C (range: 12–21°C), medium: 24.5°C (range:21–28°C) and high: 27°C (range: 26–28°C)), suggesting that early developmental patterns can be segregated by both temperature and phylogenetic relationships.
