About Tahitian prawn

Macrobrachium lar is a decapod crustacean in the family Palaemonidae. Published sources characterize its origin status as introduced. Published Kauaʻi evidence documents the species from Limahuli Stream. The cited evidence includes records dated or referenced to 1989. Evidence types include biological survey. These records establish a documented Kauaʻi occurrence but are not automatically interpreted as a present-day abundance estimate. The documented Kauaʻi habitat context includes freshwater stream, brackish/estuarine juvenile habitat, and amphidromous stream-to-sea corridor. For current-status context, current Kauaʻi presence supported by state aquatic-resources information. State information identifies this species as introduced to Hawaiʻi through aquaculture in 1950; juveniles use brackish or salt water while adults occur in freshwater. The available Kauaʻi evidence does not support adding island-specific claims about diet, reproduction, behavior, population size, or trend unless those points are stated in the cited sources, so they are not inferred here. Keeping the accepted taxonomic concept together with the dated occurrence evidence allows later surveys to distinguish historical documentation from contemporary status.
