This study evaluated whether the Emperor tetra (<i>Nematobrycon palmeri</i>), a tropical ornamental fish, can modulate sexual maturation in response to artificial light regimes. Juveniles of both sexes (~1-month old) were exposed for 74 days to 4 light–dark cycles: 6L:18D, 12L:12D (control, representing natural equatorial conditions), 18L:6D, and 24L:0D. Illumination was provided by LED bulbs at 65 lux. Males under the 6L:18D treatment exhibited a significantly higher incidence of sexual maturation compared with the other groups (<i>p</i> < 0.05). The 18L:6D regime also promoted earlier maturation relative to the control (<i>p</i> < 0.10), whereas continuous light (24L:0D) delayed the onset of sexual dimorphism (<i>p</i> < 0.05). Growth did not differ among treatments, confirming that rearing conditions were adequate. On the top of the fish's head, between the eyes, a translucent patch of skin with few melanophores may indicate the presence of a “pineal window,” supporting this species' capacity to perceive photoperiodic cues.

Methods for captive culture are well understood, the species is highly regarded for its muscle, roe, liver, and skin, and its resistance to many salmonid pathogens coupled with the species' affinity to trout-like water quality conditions make burbot an attractive and novel cool/cold-water aquaculture species. Methods to store unfertilized burbot eggs and reliably and completely induce tetraploidy in a burbot cohort were investigated. After determining the respective first cleavage interval (FCI), three separate groups of burbot eggs were exposed to a hydrostatic shock of 7500 psi for 10 degree minutes (°C minutes) at 60, 65, 70, 75, 80, 85, 90, 95, or 100% FCI. To assess egg storage, unfertilized eggs from three separate females were collected and uniform groups were fertilized at 0, 12, 24, 36, and 48 h post removal from female. Utilizing a hydrostatic shock at 70% of the FCI resulted in 100% putative tetraploid induction, and survival was statistically similar (<i>p</i> ≥ 0.05) to unshocked control eggs. Unfertilized eggs stored at 4°C for up to 24 h exhibited >25% relative survival at hatch relative to control eggs, fertilized directly after removal from the female.

A tetraploid population capable of successful reproduction could simplify and improve production of sterile (triploid) fish by crossing tetraploid and triploid burbot.

This review collates and consolidates empirical findings on how SCSAq is being adopted across the region and what factors are driving or hindering its scalability. Drawing from recent studies (2015 to 2025), this paper identified key practices being used, such as recirculating systems, organic inputs, local feed production, and water-saving techniques. The paper also synthesizes existing findings on factors influencing uptake such as education, access to finance, institutional support, and environmental conditions. Major barriers such as high start-up costs, poor infrastructure, and limited knowledge were also identified. Finally, the wide impacts of SCSAq is discussed, showing how it can improve food security, incomes, and ecosystem health if effectively scaled up. This review highlights the need for inclusive policies, farmer-led innovation, and cross-sector collaboration to bridge the gap between science, policy, and practice.
