“…Estas diferencias están relacionadas con el área de distribución de cada especie, con los resultados obtenidos y con el nivel de tecnología empleado en los diferentes sistemas de cultivo. Así, especies de climas templados como H. abdominalis (Lesson, 1827), H. hippocampus (Linnaeus, 1758) y H. guttulatus (Cuvier, 1829) se mantienen bien a temperaturas entre 13° y 23°C (Woods, 2000;Wilson et al, 2006;Palma et al, 2008Palma et al, , 2011Planas et al, 2008Planas et al, , 2012Martínez-Cárdenas & Purser, 2011), mientras que hipocampos con distribución preferentemente tropical [e.g., H. erectus, H. reidi, H. kuda (Bleeker, 1852), H. barbouri (Jordan & Richardson, 1908y H. trimaculatus (Leach, 1814] prefieren temperaturas >23°C (Lin et al, 2008bOlivotto et al, 2008;Murugan et al, 2009;Garcia et al, 2012;Willadino et al, 2012) (Tabla 1).…”

“…En relación con el fotoperiodo, existen trabajos que utilizan desde luz continua (24:0, L:O) (Olivotto et al, 2008) hasta fotoperiodos de 8L:16O (Koldewey, 2005). Las experiencias de Olivotto et al (2008) muestran un mayor crecimiento de juveniles de H. reidi utilizando luz continua que con un fotoperiodo de 14L:10O, lo cual atribuyen a que al ser depredadores visuales, la luz continua favorece la captura de presas durante las 24 h del día.…”

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

“…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). Consequently, most studies use enriched Artemia metanauplii as a standard for seahorse juvenile culture (Chang & Southgate, 2001;Lin et al, 2008;Olivotto et al, 2008;Hora & Joyeux, 2009;Otero-Ferrer et al, 2010). Woods (2003) found a significant better growth and survival in H. abdominalis fed diets containing 13 and 8% of DHA (relative concentration) compared with a diet having 4% of DHA.…”

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...

“…One important aspect of larval nutrition is providing adequate levels of lipids, proteins, carbohydrates, vitamins, and minerals through the diet 21,22 . Highly unsaturated fatty acids (HUFAs) including eicosapentaenoic acid (EPA, 20:5n-3), and docosahexaenoic acid (DHA, 22:6n-3) are also essential, since deficiencies in these lipids result in poor growth, low feed efficiency, anaemia, and high mortality 2,23,24 . It has been demonstrated that in the wild, marine fish larvae mainly feed on copepod nauplii and copepodites which are naturally rich in HUFAs 25,26 .…”

“…In the last decade, the increasing demand of fish by the aquarium trade has stimulated many studies on ornamental larval fish development and nutrition to improve production in captivity and thereby harnessing the aquatic biodiversity [1][2][3][4] . In many developing countries ornamental fish production through aquaculture forms an important way of income generation, but, even if the majority (> 90%) of freshwater ornamental fish are captively bred, only 25 species of marine fish are commercially produced 4 .…”

Sebae anemonefish, Amphiprion sebae, is currently one of the most demanded marine ornamental fish species in tropical countries. The development of controlled larval rearing procedures are required for the sustainable culture of these valuable fish. In the present study, the suitability of the marine rotifer Brachionus plicatilis as a starter food for larviculture of A. sebae was investigated. After the yolk absorption, the larvae were stocked in 250-l fibreglass reinforced plastic tanks under different feeding conditions: clear water rearing conditions with rotifers Brachionus plicatilis, 8-10 ml −1 for 10 days (R), green water conditions (Chlorella sp., 1.1-2.6 × 10 5 cells/ml) with rotifers (8-10 ml −1 ) offered for 10 days (C+R), green water conditions (Chlorella sp., 1.1-2.6 × 10 5 cells/ml) for 3 days followed by clear water in combination with rotifers (8-10 ml −1 ) feeding for 7 days (3C+7R), and clear water conditions with Artemia nauplii offered for 10 days (4-6 ml −1 ). After the 10-day feeding, all groups received Artemia nauplii up to 35 days post-hatching. Larval survival was counted at day 10 and at the end of the 35-day rearing experiment. At day 35, a significant survival difference was noted between the groups where rotifers were supplemented with algae versus only Artemia. At the end of the experiment, the highest survival rate (68.2 ± 2.3%) was obtained with larvae receiving only algae in the first 3 days of feeding. Lowest survival rate (23.9 ± 10.3%) was obtained with larvae receiving only Artemia for 35 days. This indicates that smaller preys are essential for clownfish larvae at first feeding. Larval length and wet weight were measured at the time of mouth opening, at days 7, 10, and 21, and at the end of the experiment (day 35). On day 35, mean length of the larvae varied significantly between the treatments. However, the final wet weight of the larvae did not vary significantly between the treatments.
