“…of similar size (Reyes‐Bustamante & Ortega‐Salas 1999; Jones & Lin 2007). Wilson and Vincent (1999) achieved a 100% survival rate until day 120 with three Indo‐Pacific seahorse species ( Hippocampus fuscus, Hippocampus barbourii and Hippocampus kuda ), but phylogenetic aspects (Casey, Hall, Stanley & Vincent 2004) or the use of copepods (Payne & Rippingale 2000) as first feeding food before Artemia , could explain these results (Gardner 2004).…”

“…Concerning breeding in captivity of H. hippocampus , although there are more than 100 successful references in ‘Aquariology Forums’, most of them are not applicable for large‐scale production operations with the aim of restocking or for commercial trade activities. Usually, live copepods or other zooplanktonic animals caught in the wild are used in seahorse culture with high survival rates (Gardner 2004; Bentivegna 2006; Jones & Lin 2007). However, copepods are not generally used for rearing marine ornamental fish as reliable large‐scale production methods are usually difficult to attain (Payne & Rippingale 2000).…”

As with many species of seahorses, Hippocampus hippocampus wild populations are being subjected to uncontrolled exploitation in their natural environment. Thus, aquaculture could contribute to satisfy the commercial demand for animals while promoting the recovery of wild stocks. The present study was conducted to compare the e¡ect of the substituting Artemia nauplii with rotifers for ¢rst feeding seahorse juveniles. Survival, growth and biochemical composition of prey organisms and ¢sh were studied during the feeding trial. In addition, to help the biometric study, an anaesthetic test was also carried out using clove oil. The results showed excellent survival (average 60%) in juveniles exclusively fed with Artemia, with better values than those reported previously obtained by other authors for this species. By comparison, high mortality and poor growth were observed during ¢rst feeding with seahorses fed on rotifers. This could have been related to the lower energy intake and poorer nutritional value of the rotifers. Furthermore, clove oil concentrations of 25 ppm were found to work well as an anaesthetic for seahorse juveniles. Overall, ¢rst feeding Artemia alone was found to be an e⁄cient and simpli¢ed method for feeding young H. hippocampus fry, building the principles for their culture for ornamental or restocking purposes.

“…Since rotifers and brine shrimp do not have this pattern of fatty acids, they can be enriched to increase the concentration of HU-FA, but it is almost impossible to reach the desired HUFA ratios in brine shrimp. Many species of seahorses cannot be raised successfully on a diet of enriched brine shrimp unless they are fed copepods for the first few days of feeding (Payne and Rippengale 2000;Gardner 2001;Kucera and Holt, Hippocampus erectus, unpublished).…”

“…A major bottleneck that does remain is that of cost-effective feeding and food production in a commercial environment. Consequently, topics such as reducing feed costs and improving seahorse growth and survival through feeding a variety of food types are the focus of such research and development (Job et al 2002;Gardner 2003;Payne 2003;Woods 2003a,b;Woods and Valentino 2003).…”

Growth of cultured seahorses (Hippocampus abdominalis) in relation to feed ration

This investigation examined the effect of varying feed ratios on cultured seahorse (Hippocampus abdominalis) growth and survival using frozen mysids (Amblyops kempii) at daily feed rations of 5, 10, 15 or 20% wet body weight. Feeding these different feed rations did not result in any significant difference in seahorse standard length after 3 months. However, seahorses fed the 10-20% rations were heavier and with higher condition factor (CF). Based on the total amount of frozen mysids offered to the seahorses, the food conversion ratio (FCR) became less efficient with increasing feed ration. However, when the actual mysid consumption was factored in there were no significant differences in FCR. There was a significant difference in daily specific growth rate (SGR), with the 5% ration having the lowest SGR. On a cost/benefit basis, based on the total amount of mysids offered the most cost effective ration for daily length and weight increase was the 5% ration. With actual mysid consumption taken into account, cost/benefit value favoured the 5 and 10% feed rations. Survival was 100% across all treatments. Based on this, a feed ration of 5-10% wet body weight per day of frozen mysids is recommended for cultured H. abdominalis.
