Control of the reproductive cycle is essential to achieve a successful aquaculture industry. Seahorse reared in captivity often shows eggs of poor quality and low offspring survival due to unsuitable rearing and nutritional protocols. This study aimed to evaluate the effect of dietary enrichment, added exclusively during the spawning season, on the egg quality of Hippocampus hippocampus. The effect of enriching mysis throughout the spawning season was analysed in terms of female fecundity, egg viability, egg size and fatty acid profile. The results showed that fecundity was not affected by the enrichment of the diet, but egg viability was increased when females were fed the enriched mysis (84.9 AE 4.1% compared to 62.2 AE 9.4%). Moreover, the content of several 22:5n-6, sum of n-6) decreased throughout the spawning season, especially in the last clutch, in eggs originated from females fed non-enriched mysis. Eggs from females fed the enriched diet maintained the fatty acid profile throughout the spawning season. In conclusion, enrichment of the diet of H. hippocampus improved egg viability and avoided a decrease in the quality of eggs by maintaining PUFA content in the last clutches of the spawning season.

“…Sin embargo, sólo recientemente se han conocido algunos procesos claves que permiten avanzar en la comprensión de la fisiología de la nutrición en los caballitos de mar. Se ha demostrado que el enriquecimiento de las dietas con ácidos grasos tiene efectos benéficos en la calidad de los ovocitos producidos por las hembras, y el perfil de ácidos grasos de la dieta tiene un efecto directo sobre su perfil en los huevos (Planas et al, 2010;Saavedra et al, 2013Saavedra et al, , 2015. Asimismo, estudios recientes han demostrado que el contenido de ácidos grasos altamente insaturados de cadena larga en la dieta, en particular el ADH, es un factor indispensable en el buen desempeño (crecimiento y supervivencia) de juveniles de H. erectus (Vite-García et al, 2014b;Zhang et al, 2015a), ya que cumplen funciones importantes como promover el metabolismo de lípidos, reducir los productos de la peroxidación de lípidos y mejorar la defensa antioxidante en los juveniles (Yin et al, 2012).…”

Review Avances en el cultivo deRESUMEN. Las poblaciones de caballito de mar (género Hippocampus) han sido impactadas de diferentes formas por el ser humano. Por esta razón, se han implementado medidas para mitigar el decremento de las poblaciones, como su inclusión en la lista de CITES, lo cual regula en parte su comercialización. Sin embargo, se deben adoptar otras medidas para asegurar la conservación de estas especies. La acuicultura se presenta como una oportunidad que puede traer beneficios en diferentes formas: reemplazando la captura del medio natural, repoblando cuerpos de agua cuyas poblaciones se encuentren impactadas y como actividad económica redituable. Desde inicios del presente siglo, se ha generado información relevante en torno a las condiciones de cultivo de diferentes especies de caballito de mar, desde los parámetros físicos y químicos del agua y otras condiciones físicas como tipos y tamaños de los tanques, hasta cuestiones relacionadas con la nutrición, la supervivencia, el crecimiento, la maduración y el proceso reproductivo. En este trabajo se recopila esta información, con énfasis en las investigaciones relacionadas con las especies americanas. Palabras clave: Hippocampus, caballito de mar, ornamentales marinos, acuicultura. However, other measures must be taken to ensure the conservation of these species. Aquaculture is presented as an opportunity that can bring benefits in different ways: replacing capture from natural environments, repopulating water bodies whose populations are impacted and as a profitable economic activity. From the beginning of this century, relevant information has been generated about the culture conditions of different species of seahorses, from the physical and chemical parameters of water and other physical conditions such as types and sizes of tanks, to issues related to nutrition, survival, growth, maturation and reproductive processes. This paper presents a collection of such information, with some emphasis on works related to species in the Americas. Culture conditions for

“…H. hippocampus broodstock fed a docosahexaenoic acid (DHA, 22:6n-3) depleted diet produce newborns that have 7% of DHA, compared to 16% in broodstock fed mysids with more DHA (Otero-Ferrer et al, 2012). Newly born seahorse have high levels of HUFA, particularly DHA with levels above 20% relative to total fatty acids in H. kuda (Saavedra et al, 2013) and levels of 16-17% for H. guttulatus (Faleiro & Narciso, 2011. These high DHA levels decrease as juveniles grow if given a DHA-depleted diet, as is the case with non-enriched Artemia nauplii, and this decrease has been associated to a decrease in survival (Chang & Southgate, 2001;Shapawi & Purser, 2003;Wong & Benzie, 2003), with the exception of juvenile H. guttulatus, which did worse when fed with enriched Artemia nauplii (Palma et al, 2011).…”

ABSTRACT. Survival during first months after birth is one of the bottlenecks for consolidating the seahorse farming industry. In this work, Artemia metanauplii enriched with two highly unsaturated fatty acids (HUFA) rich commercial emulsions with different docosahexaenoic acid (DHA) levels (63% and 14% of total lipids), a vegetable oil with no DHA, and non-enriched Artemia as control, were used to feed 5-day-old juvenile Hippocampus erectus for 60 days. Enriched Artemia had similar levels of DHA (13% and 9%), despite great differences of DHA in the emulsions, with traces of DHA in non-enriched and vegetable oil enriched Artemia. More than 20% of DHA was found in 24 h starved juveniles fed both DHA-enriched treatments, similar to values in newly born juveniles, but those fed vegetable oil enriched Artemia or non-enriched Artemia had 5% of DHA. Total lipid and protein levels were similar in juveniles from the four treatments. The n-3/n-6 ratio was almost four-fold higher in seahorses fed DHA-enriched treatments compared to juveniles fed the nonenriched treatments. Survival of seahorses only partially reflected the DHA levels: it was lower in the vegetable oil treatment, similar in the seahorses fed Artemia with higher DHA and in the control treatment, and higher in seahorses fed the HUFA-enriched Artemia with lower DHA levels, although growth was similar in the two DHA-enriched Artemia treatments. Juvenile H. erectus seahorses perform better when they have at least 20% of DHA in their tissues, and these levels can be attained with no more than 14% of DHA in emulsions, eliminating the need for more expensive emulsions with higher DHA levels. Keywords: Hippocampus erectus, seahorse, DHA, growth, fatty acids, survival, aquaculture.Crecimiento y sobrevivencia de juveniles de Hippocampus erectus (Perry, 1810) alimentados con Artemia con diferentes niveles de HUFA RESUMEN. La sobrevivencia durante los primeros meses de vida es uno de los cuellos de botella para la consolidación de la industria del cultivo del caballito de mar (Hippocampus erectus). En este trabajo se utilizaron metanauplios enriquecidos con dos emulsiones comerciales, con diferentes niveles de ácido docosahexaenóico (DHA) (63% y 14%), con aceite vegetal sin DHA, y metanauplios sin enriquecimiento como control, para alimentar caballitos de mar de 5 días de vida durante 60 días. La Artemia enriquecida tuvo niveles similares de DHA (13% y 9%), a pesar de las grandes diferencias en las emulsiones, con trazas de DHA en la Artemia no enriquecida y la enriquecida con aceite vegetal. Se obtuvo más de 20% de DHA en juveniles, muestreados con 24 h de ayuno, de los tratamientos con enriquecimiento de DHA, con valores similares a los de caballitos recién nacidos, pero los caballitos que se alimentaron con Artemia enriquecida con aceite vegetal y con Artemia no enriquecida tuvieron 5% de DHA. Los lípidos y proteínas totales fueron similares en los caballitos de los cuatros tratamientos. La razón n-3/n-6 fue casi cuatro veces mayor en caballitos alimentados con los t...
