“…Within the Ovalentaria a similar development is only known in mugilids, wherein ural centrum 1 emerges anterior to the lower hypurals and ural centrum 2 anterior to the upper hypurals and both fuse to form a compound centrum with an identical shape to the compound centrum of atherinomorphs [62]. In the other previously studied ovalentarian taxa, only one elongated ural centrum develops that covers the notochord from the beginning of the parhypural almost to the caudal tip of the notochord [57][58][59][60][61]63]. During ontogeny this centrum also shortens and in adults has a similar shape as in atherinomorphs and mugilids [1].…”

“…For many of the contemplable taxa studies on the development of the caudal fin are scarce or missing. For blenniids [57], cichlids [58,59] and clinids [60,61] there is some ontogenetic data, and for mugilids [62] and pomacentrids [63] detailed descriptions are available. Similarities between the caudal-fin development of these taxa and the Atherinomorpha include autogenous development of the parhypural and the epurals, the autogenous development of some haemal and neural spines of the preural centra (i.e., preural centra 2 and 3 in mugilids and at least preural centra 2 and 3 in blenniids, cichlids and pomacentrids) [59,60,62,63].…”

Background The caudal fin of teleosts is a highly diverse morphological structure and a valuable source of information for comparative analyses. Within the Atherinomorpha a high variation of conditions of the caudal-fin skeleton can be found. These range from complex but basal configurations to simple yet derived configurations. When comparing atherinomorph taxa, it is often difficult to decide on the homology of skeletal elements if only considering adult specimens. However, observing the development of caudal-fin skeletons allows one to evaluate complex structures, reveal homologies and developmental patterns, and even reconstruct the grundplan of the examined taxa. Results We studied the development of the caudal-fin skeleton in different atheriniform, beloniform and cyprinodontiform species using cleared and stained specimens. Subsequently we compared the development to find similarities and differences in terms of 1) which structures are formed and 2) which structures fuse during ontogeny. For many structures, i.e., the parhypural, the epural(s), the haemal and neural spines of the preural centra and the uroneural, there were either no or only minor differences visible between the three taxa. However, the development of the hypurals revealed a high variation of fusions within different taxa that partly occurred independently in atheriniforms, beloniforms and cyprinodontiforms. Moreover, comparing the development of the ural centra exposed two ways of formation of the compound centrum: 1) in atheriniforms and the beloniforms Oryzias and Hyporhamphus limbatus two ural centra develop and fuse during ontogeny while 2) in cyprinodontiforms and Exocoetidae (Beloniformes) only a single ural centrum is formed during ontogeny. Conclusions We were able to reconstruct the grundplan of the developmental pattern of the caudal-fin skeleton of the Atheriniformes, Beloniformes and Cyprinodontiformes as well as their last common ancestors. We found two developmental modes of the compound centrum within the Atherinomorpha, i.e., the fusion of two developing ural centra in atheriniforms and beloniforms and the development of only one ural centrum in cyprinodontiforms. Further differences and similarities for the examined taxa are discussed, resulting in the hypothesis that the caudal-fin development of a last common ancestor to all atherinomorphs is very much similar to that of extant atheriniforms.

The identification of skeletal elements, the analysis of their developmental sequence, and the time of their appearance during larval development are essential to broaden the knowledge of each fish species and to recognize skeletal abnormalities that may affect further fish performance. Therefore, this study aimed to provide a general description of the development of the entire skeleton highlighting its variability in Cichlasoma dimerus. Larvae of C. dimersus were stained with alcian blue and alizarin red from hatching to 25 days posthatching. Skeletogenesis began with the endoskeletal disk and some cartilage structures from the caudal fin and the splachnocranium, while the first bony structure observed was the cleithrum. When larvae reached the free‐swimming and exogenous feeding stage, mostly bones from the jaws, the branchial arches, and the opercle series evidenced some degree of ossification, suggesting that the ossification sequence of C. dimerus adjusts to physiological demands such as feeding and ventilation. The caudal region was the most variable regarding meristic counts and evidenced higher incidence of bone deformities. In conclusion, this work provides an overview of C. dimerus skeletogenesis and lays the groundwork for further studies on diverse topics, like developmental plasticity, rearing conditions, or phylogenetic relationships.

“…La mayoría de las deformaciones esqueléticas genéticas en peces aparecen en las etapas de larvas y juveniles; son de considerable interés, debido a que reducen la sobrevivencia larvaria y el crecimiento de los peces en los laboratorios, y en las granjas de engorde los peces deformes deben ser descartados o vendidos a un menor precio (Gisbert, Fernández & Estévez, 2008). El 6,43 % de las deformidades esqueléticas observadas se consideran bajas en comparación con otros peces marinos (entre 15 y 50 %) (Boglione et al, 2001); sin embargo, es posible que aumente, si se aplican metodologías de doble tinción para análisis esqueléticos que permiten transparentar los tejidos de las larvas y evidenciar malformaciones óseas en cráneo, columna y complejo caudal, entre otros (Gisbert, Alcaraz, Tovar-Ramírez & Álvarez-González, 2014).…”

La base tecnológica para la acuicultura del Lutjanus guttatus fue desarrollada en Costa Rica desde el 2002 por el Parque Marino del Pacífico. Las primeras producciones en masa de juveniles se obtuvieron en el 2005, las granjas comerciales a pequeña escala se establecieron a partir del 2006 y la primera transferencia de tecnología al sector privado inició en el 2008. A partir de estos avances se identificó la necesidad de optimizar la producción de juveniles. Con este objetivo, se evaluaron y describieron biológicamente tres cultivos larvarios obtenidos de desoves naturales de reproductores de segunda generación (F2). Tres familias n = 8 cada una; 1,45 ± 0,21 kg; 1,33 ± 0,12 kg; y 1,28 ± 0,10 kg provenientes de una granja acuícola se aclimataron en el laboratorio hasta que desovaron. Se incubaron 100 mil huevos por desove (densidad: 520 huevos mL-1). Las larvas (90 mil/tanque) fueron sembradas con una longitud total (Lt) inicial de 2,25 mm y alimentadas con rotíferos enriquecidos, microalgas producidas en fotobiorreactores helicoidales y nauplios de artemia. El crecimiento, sobrevivencia, canibalismo, variabilidad del tamaño y deformidades presentadas fueron registradas. Un total de 22 837 juveniles fueron cosechados en el día 60 después del desove. Durante la cosecha se obtuvo una longitud total del juvenil (Lt) de 57,8 ± 7,82 mm, tasa de crecimiento absoluto (TCA) 0,93 mm d-1, tasa de crecimiento específico (TCE) 5,41 % d-1, factor de condición (K) 1,089; una sobrevivencia promedio de 8,4 % y 6,3 % de deformidades totales a la vista. Las metodologías utilizadas para obtener un desove natural de calidad, la mejora de alimento vivo producido por fotobiorreactores y la separación por tamaño fueron aspectos efectivos para el cultivo larval de la especie, aunque la inanición en los primeros días de alimentación exógena, la metamorfosis y el canibalismo siguen siendo factores que afectan la sobrevivencia final.
