“…It is known that in marine organisms, including crustaceans, pigment content determines egg quality to a great extent due to its critical role in many metabolic processes, including egg respiration and vitamin A production, its protective action against the effects of oxygen, UV and ionizing radiation, and its function in gene expression, among others (Craik 1985, Kalinina et al 2009, Wade et al 2015. Egg colour progression throughout embryogenesis is common in crustaceans, and in general terms it reflects the initial consumption of typically yellow or orange-coloured yolk, superimposed on the production of red-, brown-and greycoloured pigments on chromatophores and eyes during advanced stages (Sigana 2002, Parimalam 2001.…”

Summary:The embryogenesis of Ovalipes trimaculatus, a member of the highly valued portunid swimming crabs, was studied under nearly constant temperature (13±1°C), salinity (33) and photoperiod (14 h light:10 h dark) conditions. A five-stage scale of embryonic development was defined for the species. Time required to complete development averaged 35.7±2.11 days, showing no significant differences between embryos located in inner, middle and outer portions of the egg mass. The egg chorion was rounded and showed the highest growth in diameter between stages I (morula-blastula-gastrula) and II (primordium of larval structure) and between stages III (appendage formation) and IV (eye formation). Results reported here provide a baseline for optimizing hatchery operations and useful information for management purposes.Keywords: crustacean; crabs, aquaculture; Ovalipes trimaculatus; embryology.Desarrollo embrionario del cangrejo nadador Ovalipes trimaculatus (Decapoda: Brachyura: Portunoidea) Resumen: Se estudió la embriogénesis del cangrejo nadador Ovalipes trimaculatus, miembro de la familia de portúnidos altamente valorados, bajo condiciones constantes de temperatura (13±1°C), salinidad (33) y fotoperíodo (luz 14h:10h oscuridad). Se definió una escala de cinco etapas de desarrollo embrionario para la especie. El tiempo necesario para completar el desarrollo es de 35.7±2.11 días, sin mostrar diferencias significativas entre embriones ubicados en porciones interior, media y exterior de la masa de huevos. Los huevos son esféricos y presentan mayor crecimiento en diámetro entre las etapas I (mórula -blástula -gástrula) y II (primordio de estructuras larvarias) y entre las etapas III (formación de apéndices) y IV (formación de los ojos). Los resultados aquí presentados proporcionan la base para la optimización del cultivo y brindan información útil para el manejo de la especie.Palabras clave: crustáceos; cangrejos; acuicultura; Ovalipes trimaculatus; embriología.Citation/Como citar este artículo: Martelli A., Tapella F., González-Pisani X., Dellatorre F., Barón P.J. 2016.

“…As in amphibians, the predominant form of vitamin A in many fish eggs is retinal, but retinol, retinyl esters and carotenoids can also be found in significant quantities (Irie and Seki, 2002). In fact, the bright yellow orange or red colour of many fish eggs is due to the presence of carotenoid pigments (Craik, 1985). Salmonids generally take up carotenoids, predominantly, canthaxanthin and astaxanthin, from the diet and deposit them in muscle.…”

“…The concentrations of carotenoids and vitamin A forms in eggs of teleost fishes varies widely and can even vary widely within a species, as reviewed by Craik (1985). Carotenoids are generally more concentrated in eggs of salmonids in which post-fertilisation development takes place in low oxygen environments (i.e.…”

“…The role of vitamin A and carotenoids for determining egg and early life stage quality has been a controversial subject for over 50 years (Izquierdo et al, 2001;Craik, 1985). The few available carefully designed studies suggest that enhanced concentrations of some carotenoids are associated with better egg condition and increased measures of survival.…”

“…Vitamin A is required for growth, reproduction and embryonic development of fish and must be obtained from the diet, because fish are incapable of synthesising the vitamin (Craik, 1985;Madden, 2001).Vitamin A is present in fish in many forms, including the free alcohol form retinol (Vitamin A1) and the closely related dehydroretinol (Vitamin A2) form, which differs from vitamin A1 by only one double bond (Fig. 2).…”

SUMMARY: Early development in fish is dependent on essential nutrients present in the egg. Vitamins E and A are critical to the normal development of fish embryos. Vitamin E functions primarily as an antioxidant to protect unsaturated lipids from oxidative degradation. Vitamin A or its provitamin carotenoid forms support growth, are required for the differentiation and maintenance of epithelial tissue and can be converted to forms of the vitamin that are potent morphogens. Fish cannot synthesise either of the vitamins, so the maternal dietary content of each prior to oogenesis is an important determinant of reproductive fitness. Here we review the basic metabolism of vitamins E and A and carotenoids and their processing from the maternal diet and deposition into eggs. Evidence for the link between levels of each of the vitamins in eggs and measures of reproductive fitness are also discussed. -El desarrollo embrionario en peces es dependiente de los nutrientes esenciales presentes en el huevo. Las vitaminas E y A son críticas en el desarrollo normal de los embriones de los peces. La vitamina E funciona sobre todo como un antioxidante para proteger los lípidos no saturados contra la degradación oxidativa. La vitamina A, o los carotenoides formas de provitamina, se requieren para la diferenciación y el mantenimiento del tejido fino epitelial y se puede convertir a las formas de la vitamina que son morfogenes potentes. Los peces tampoco pueden sintetizar las vitaminas, de modo que el contenido dietético materno de cada una antes de la oogenesis es un determinante importante de la aptitud reproductiva. Aquí repasamos el metabolismo básico de las vitaminas E y A y los carotenoides y su procesamiento desde la dieta materna a la deposición en los huevos. Se discute también la evidencia del acoplamiento entre los niveles de cada una de las vitaminas en los huevos y las medidas de aptitud reproductiva en los adultos.
