Effects of vitamin A palmitate, β-carotene and retinoic acid on the growth and incidence of deformities in larvae of red sea bream Chrysophrys major

 The effects of vitamin A palmitate (VAP; 2.7, 27 and 165 mg/100 g diet), β-carotene (βC; 1, 9 and 50 mg/100 g diet) and retinoic acid (RA; 2.8, 28 and 166 mg/100 g diet) on the incidence of deformities in red sea bream (Chrysophrys major) larvae were examined using zein-based micro-bound d...

Growth (final body weight, weight gain and total length) and survival rate were affected by the increasing supplementation of these compounds. The abnormalities observed in the larvae included the compression or apparent fusion of the segments in the notochord and mouth deformities. Compression/apparent fusion of the segments was detected mainly in vertebrae of the hemal zone, affecting the total length of larvae. Incidence of these deformities increased with increasing levels of VAP, βC and RA in the diets, but a significantly higher percentage of affected vertebrae was observed in the larvae fed the diets containing RA. The effect of βC was unclear in the present experiment, since only the highest concentration caused significant incidence. The results of this study show that dietary vitamin A may be related to the vertebral deformities in red sea bream larvae. Se examinaron los efectos del palmitato de vitamina A (VAP; 2.7, 27 y 165 mg/100 g dieta), el β-caroteno (βC; 1, 9 y 50 mg/ 100 g dieta) y el ácido retinoico (RA; 2.8, 28 y 166 mg/100 g dieta) en la incidencia de deformidades de larvas de pargo rojo (Chrysophrys major) utilizando micro dietas con zeina durante 15 días. Crecimiento (peso final, ganancia en peso y longitud total) e índice de supervivencia fueron afectados por el incremento en la suplementación de esos compuestos. Las anormalidades observadas en las larvas fueron compresión o fusión aparente de los segmentos de la notocorda y deformidades en la boca. La compresión/fusión aparente de los segmentos se detectó principalmente en las vertebras de la zona hemal, afectando la longitud total de las larvas. La incidencia de estas deformidades se incrementó con el aumento de los niveles de VAP, βC y RA en las dietas, pero se observó un porcentaje significativamente más alto de vértebras afectadas en las larvas alimentadas con las dietas con RA. El efecto del βC no fue claro en el presente estudio, ya que sólo la concentración más alta provoco una incidencia de deformidades significativa. Los resultados del presente estudio muestran que la vitamina A en la dieta podría estar vinculada a las deformidades vertebrales en larvas del pargo rojo. 2006-05-24 2021-06-03T03:55:07Z 2021-06-03T03:55:07Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed research note Nota de investigación arbitrada https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1026 10.7773/cm.v32i12.1026 https://hdl.handle.net/20.500.12930/7384 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1026/929 application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 32 No. 1B (2006); 195-204 Ciencias Marinas; Vol. 32 Núm. 1B (2006); 195-204 2395-9053 0185-3880
