“…Although a number of studies on breeding and juvenile culture of seahorses have been conducted (Woods , , ; Lin, Lu, Gao, Shen, Cai & Luo ; Lin, Gao, Sheng, Chen, Zhang & Lu ; Lin, Lin & Zhang ; Murugan et al . ), there were only few studies that precisely described an appropriate feeding regime which can improve survivorship of early juveniles and can be consequently applied to a large‐scale rearing of juvenile seahorses. Current functional approach for seahorse aquaculture is a small‐scale intensive system (i.e.…”

Feeding selectivity of the seahorse,Hippocampus kuda(Bleeker), juveniles under laboratory conditions

This study examined the feeding selectivity of Hippocampus kuda juveniles under captive conditions and evaluates different food organisms that could be used to improve hatchery‐rearing of this species. Newly born H. kuda were reared for 10 days in 60‐L capacity tanks and fed rotifers (Brachionus rotundiformis), zooplankton (mostly Pseudodiaptomus annandalei and Acartia tsuensis) alone or both food sources. The size and amount of food ingested increased as seahorses grew. Selective feeding of seahorses appeared to change as they develop, preferring copepod adults over nauplii and rotifers. A. tsuensis was highly selected by juveniles over P. annandalei. Specific growth rate in terms of body weight (SGR‐BW, 15% day–1) was the highest and mortality rate (9% at day 10) the lowest in seahorses fed a mixed food sources. Slowest growth rate (0.3% day–1) and highest mortality rate (60% at day 7) were observed in seahorses fed rotifers alone. These results indicate that copepods are suitable food for seahorse juveniles, but a mixture of food organisms in the rearing tank environment enhances survivorship and growth of H. kuda, thus potentially providing a source of cultured rather than wild specimens for characterizing the life history of this threatened species.

Interpretation and implementation of the ConventionCompliance and enforcement Review of Significant Trade in specimens of Appendix-II species [Resolution Conf. 12.8 (Rev. CoP13)] SPECIES SELECTED FOLLOWING COP151. This document has been prepared by the Secretariat. 3. At its 26th meeting (AC26, Geneva, 2012), the Committee reviewed the available information on these taxa in accordance with paragraph f) of Resolution Conf. 12.8 (Rev. CoP13). In instances where the Committee was satisfied that Article IV, paragraph 2 (a), 3 or 6 (a), was correctly implemented, it eliminated the species from the review with respect to the range State concerned, and these range States were notified accordingly by the Secretariat (see document AC26 Doc.12.3 and the summary record of AC26). At its 25th meeting (AC25,Geneva4. At AC26, the Committee also agreed that prior to the compilation of information called for in paragraph g), range States that had been kept in the process due to a lack of response but where no commercial trade had been recorded over the most recent 10 years, would be removed from the process in consultation with the Animals Committee. The taxa and range States that were thus retained in the review are shown in the table below. Taxa selected following CoP15 and retained in the review after AC26 Taxon selected Range StateMacaca fascicularis Cambodia; India, Indonesia, Lao People's Democratic Republic, Mauritius, Palau, Philippines, Viet Nam Psittacus erithacusBenin, Central African Republic, Ghana, Nigeria, Togo, Uganda Chamaeleo gracilisBenin, Cameroon, Ghana, Guinea, Togo, Uganda Chamaeleo senegalensisBenin, Ghana, Guinea, Mali, Senegal, Sierra Leone Trioceros melleri Mozambique Trioceros quadricornisCameroon, Nigeria Trachyphyllia geoffroyi Singapore, Solomon Islands 5. In accordance with paragraph g) of the Resolution, the Secretariat proceeded with the compilation of information regarding the species mentioned in the table above. The UNEP World Conservation Monitoring Centre (UNEP-WCMC) was engaged to compile information about the biology and management of and trade in these species, and to provide a preliminary categorization of the species in compliance with paragraphs h) and i). The Secretariat transmitted the resulting reports from UNEP-WCMC to relevant range States on 13 and 19 December 2013, which had 60 days to submit comments in accordance with paragraph j). Kinyongia fischeri United Republic of Tanzania Kinyongia tavetana United Republic of Tanzania Ptyas mucosus6. The species reports of UNEP-WCMC present conclusions about the effects of international trade on the selected species, the basis on which such conclusions are made, and problems with the implementation of Article IV of the Convention. They provide preliminary categorizations of each species into one of the three categories outlined in paragraph i) of Resolution Conf. 12.8 (Rev. CoP13), namely: i) 'species of urgent concern' shall include species for which the available information indicates that the provisions of Article IV, paragraph 2 ...

“…The low mortality rate observed in the pipefish cultured in 0 g/L suggests that the acclimation rate used in this study was adequate for M. brachyurus , while the mortalities in the pipefish cultured in 16 g/L could have more relation to poor adaptation of the species to that salinity, given the symmetrical acclimation protocol used. Although Murugan et al () gradually reduced 1 g/L every 48 h by adding distilled water from Hippocampus trimaculatus rearing salinity of 35 g/L, the study focused on finding a salinity level in which 100% mortality occurred. Poor adaptation of M. brachyurus exposed to 16 g/L may explain the decline in survival after the first week of the experiment.…”

Natural populations of the opossum pipefish, Microphis brachyurus, are affected in Mexico by anthropogenic alteration of their habitat and unregulated fishing as this species is traded as an aquarium fish without formal records as occurs with other syngnathids around the world. M. brachyurus is an estuarine fish adapted to salinity fluctuations. The aim of this study was to examine the effect on growth, condition, and survival of juvenile pipefish cultured for 4 wk at salinities of 0, 8, and 16 g/L. Pipefish were fed enriched Artemia nauplii maintaining a ration rate of 14% body weight per day (dry weight Artemia: wet weight fish). Pipefish cultured at 16 g/L showed lower survival (40%) than those at 0 and 8 g/L (100 and 96%, respectively), while juveniles cultured in 8 and 16 g/L were heavier (0.393 and 0.388 g, respectively), longer (9.9 cm), and grew faster (1.4) than those in 0 g/L (0.294 g, 9.1 cm, and 0.44, respectively). This study is the first to report that a salinity of 16 g/L compromises M. brachyurus culture potential and a salinity of 0 g/L caused poor growth while the optimal salinity for the species appears to be around 8 g/L.
