#fish fry
- Alevin — A freshly hatched fish larva, in the first stage of post-embryonic development, characterized by the presence and absorption of the external yolk sac which provides its initial nutrition. It represents an extremely vulnerable and critical biological stage in pisciculture management and aquatic ecology, preceding the fry stage capable of independent planktonic feeding.
- Alevinage — The action of stocking a fish pond, lake, or running watercourse with alevins or fish fry for biological restocking, sport fishing, or commercial production; alevinage. The term defines a set of controlled agro-piscicultural techniques designed to ensure the acclimatization and survival rate optimization of fish larvae in the new aquatic ecosystem.
- Alvin — A masculine given name of Old Germanic origin, structurally meaning 'noble friend', 'friend of the elfs', or 'wise protector'; also, in international ichthyology and marine biology, the term denotes a newly hatched fish larva or fry that draws nutrients from its yolk sac.
