Special Issue Information

Dear Colleagues,

Ornamental fish keeping has a long history, which can be traced back to ancient China. They are often called living jewels because of their colors, shapes and behaviors. Modern ornamental fishkeeping is one of the most popular hobbies in the world, and its trade represents an important economic sector. Now an estimated 1.5 billion fish are sold worldwide each year comprising 3,500 species of plants, invertebrates and fish. And, according to the feeding characteristics of fish, they are divided into three categories: tropical freshwater, temperate (coldwater) freshwater and marine ornamentals. However, ornamental fish farming still faces many challenges, such as the losses caused by transport stress and handling; the outbreak of diseases that need to be improved; the development of feed formulations that enhance color and disease resistance; and germplasm degradation in many artificial varieties and high-quality varieties requiring further development, etc. This Special Issue focuses on the current state of ornamental fish aquaculture, covering topics on ornamental fish reproductive biology, genetic breeding and quality improvement, traditional and novel aquaculture feeds, diseases and prevention, and sustainable aquaculture. 


In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

Ornamental fish reproductive biology;

Genetic improvement in ornamental fish quality;

Nutritional and functional feed for ornamental fish;

Ornamental fish diseases and prevention;

Management and sustainable development of ornamental fish farming.

I look forward to receiving your contributions.

Discus fish, Symphysodon spp., have a unique parental care strategy where the fry feed on their parents’ skin mucus after hatching. Here, lipidomics was employed to compare the skin mucus lipid profiles of male or female discus fish during parental and non-parental care. By multivariate statistical analysis, clear separations were found between parental and non-parental female and between parental and non-parental male discus. In the comparison between female discus in the parental and non-parental stages, a total of 107 differentially expressed lipids (DELs) were observed, of which 23 showed increased levels during parental care. For male discus, a total of 108 DELs were found, of which 46 displayed increased levels during parental care. The main DELs were phosphatidyl ethanolamine and phosphatidylinositol, mainly involved in arachidonic acid and sphingolipid metabolism pathways. Further, by comparing parental male and female discus, we found 47 DELs involved in the glycerophospholipid metabolism pathway. Diglyceride showed a higher concentration in the skin mucus of parental females, while phospholipids showed a higher level in that of parental males. Our results revealed changes in the skin mucus lipid profiles of discus fish during parental care, as well as sex-dependent differences between parental fish. Full article
