“…Woods (2000a) obtained 86% survival after four weeks for H. abdominalis fed with high quality Artemia cysts and algal enrichment. Both survivals were higher than those in this study, relative with live prey with high nutritional content (copepod and enriched Artemia, Payne et al, 1998;Payne and Rippingale, 2000). And culture with flowing water and a shorter experimental period were other conditions.…”

A two-month study was conducted to test the effects of macroalgae on the growth and survivorship of juvenile lined seahorse (Hippocampus erectus) in aquaria. Twenty-day old seahorses were cultured in the tanks with green alga Chaetomorpha linum, red alga Gracilaria tikvahiae, green plastic artificial plant (stargrass), and black plastic net, respectively. Increases in wet mass and standard length for the seahorses were significantly higher in the tanks with macroalgae than those without macroalgae. The seahorse survivorships in the two macroalgal treatments were also significantly higher than those of the two treatments without macroalgae. In the treatments with macroalgae, the DO and pH were higher than those without marcoalgae. During the experiment, the color of seahorses was changed to certain extent. In the green background (the treatments with C. linum and stargrass), 24.1%-28.4% of black seahorses decreased over time; whereas in the black (plastic net) or brown (G. tikvahiae) background treatments, 14.1%-16.3% of yellow seahorses decreased over time, for matching that of the background. Furthermore, the survival rate of seahorse was correlation with DO and pH, and strong correlation with standard length, wet mass and CF. Polyculture with macroalgae, survival rates of seahorse were higher than without macroaglae.

“…S. nigra hatchlings are smaller (ca. 10 mm SL) than those caught in trawls (41–52 mm SL) suggesting longer pelagic larval duration (Kendrick & Hyndes 2003); based on growth rates of congeners in culture (1.5 mm day −1 ; Payne et al. 1998) and confamilials in the wild (Takahashi et al.…”

Parallel phylogeographic structure in ecologically similar sympatric sister taxa

Present-day phylogeographic patterns have been shaped by the dual histories of lineages and places, producing a diversity of relationships that may challenge discovery of general rules. For example, the predicted positive correlation between dispersal ability and gene flow has been supported inconsistently, suggesting unaccounted complexity in theory or the comparative framework. Here, I extend the sympatric sister-species approach, in which variance between lineages and places is minimized, to sister clades and test a fundamental assumption of comparative genetic studies of dispersal: that taxa which evolved at the same time and in the same place will, if they have similar life histories and ecologies, have essentially the same phylogeographic structure. Phylogenetic analyses of 197 Stigmatopora pipefishes using two nuclear (creatine kinase intron 6, α-tropomyosin) and two mitochondrial (16S, noncoding region) loci revealed largely synchronous parallel diversification of sister clades that are codistributed from Western Australia to New Zealand, supporting the null hypothesis. Only one comparison, however, yielded a sympatric sister-species pair (the two stem species), so I also explored the potential for extant species sharing a substantial proportion of their evolutionary histories in sympatry to substitute for sister taxon comparisons. In eastern Australia, where strong environmental structure is lacking, phylogeographic differences between species that have been codistributed for ~85% of their evolutionary histories were consistent with tendencies favoured by their modest life-history differences, that is the larger, rarer species had lower genetic diversity. In contrast, in New Zealand, two species codistributed for ~70% of their evolutionary histories were both structured similarly by a strong biogeographic filter despite differences in life history. Rigorously quantifying the influence of intrinsic and extrinsic factors on phylogeographic structure may advance most efficiently through meta-analyses of contemporaneously codistributed taxa, including but not limited to sympatric sister species.

“…Numerous captive breeding and aquaculture ventures have emerged for seahorses and, to a lesser extent, pipefishes (Kaiser et al , 1997; Payne et al , 1998; Partridge et al , 2004; Koldewey & Martin‐Smith, 2010). There are many concerns about how aquaculture practices in general can damage marine environments and affect wild populations of the farmed species through disease transmission or escapes (Naylor et al , 2000).…”

This article analyses the pressures on seahorses and explores conservation responses. It focuses on seahorses (Hippocampus spp.) but also considers pipefishes and seadragons, especially where they can fill gaps in seahorse knowledge. The charisma of many syngnathids can make them good flagship species for threats and solutions in marine conservation. The article combines a synthesis of published literature with new data on the trade in seahorses for traditional medicine, aquarium display and curiosities. Most traded seahorses come from trawl by-catch, although seahorses are also targeted. The total extraction is large, tens of millions of animals annually, and unsustainable. A first review of the effect of habitat change on syngnathids raises many questions, while suggesting that some species may cope better than others. The combination of pressures means that many species of syngnathid are now included in the IUCN Red List of Threatened Species or national equivalents. In addition, seahorse exports from 175 countries are limited to sustainable levels under the Convention on International Trade in Endangered Species (CITES) of Wild Fauna and Flora. Possible conservation measures include marine protected areas, fisheries management, select aquaculture ventures, trade regulation, improved governance (particularly) and consumer engagement.
