lankkua

Lankkua is a species of freshwater fish described from the river systems of the Lankua Basin in the fictional continent of Avelora. It belongs to the genus Lankua in the family Lankuidae, both taxa created for this article. Adults typically reach 25–28 cm in length, with a slender body, a silvery-blue sheen, and a distinctive lateral line. The dorsal fin has yellow margins, and the fish shows moderate migratory behavior associated with seasonal floods.

Etymology and naming: The name lankkua derives from the Lankua language, where lan means water and kua means light. Because of its shimmering appearance in sunlight, the fish is a familiar symbol in local storytelling. Genetic studies cited in regional reports suggest limited diversification within the Lankua Basin.

Habitat and ecology: Lankkua inhabits clear, slow-moving rivers and floodplain lakes. It is omnivorous, feeding on aquatic invertebrates, algae, and detritus. Spawning occurs in shallow gravel during rising waters; eggs are laid in gravel and guarded by one or both parents in some populations.

Uses and cultural significance: In local fisheries, lankkua is a valued food source, commonly smoked, grilled, or used in stews. The fish appears in folklore related to river fertility and seasonal renewal, and is sometimes featured in regional crafts and art associated with water symbolism.

Conservation and research: There is no global conservation status for lankkua in this fictional setting. Threats include habitat modification, dam construction, and water pollution. Ongoing research covers life history, migration timing, and sustainable fishing practices conducted by regional universities and institutes.
