Current distribution status, habitat use, life history and abundance of Macrobrachium carcinus

Project Description

Current distribution status, habitat use, life history and abundance of Macrobrachium carcinus. Loss of flow and altered habitat affect travel-time of the larvae and its estuarine life stages. This project will also evaluate barrier-effect on M. carcinus abundance based on various dam structure types. Comparison of historic data to post dam removal (ex: Ottine Dam) data will build a stronger case for natural flows.

Conservation Area

Guadalupe and San Antonio Rivers Native Fish Conservation Area, Central Coast Rivers and Streams Native Fish Conservation Area

NFCA Objectives

Project Hierarchy: High (i.e., timely and urgent, needs to occur within the next 1-3 years)
Estimated Cost Range: $50,000-$100,000
Project Submitted By: Archis Grubh, TPWD
Suggested Contact:

Fill data gaps on the distribution, abundance, and life history of M. carcinus. Evaluating harvest limits will hlep management actions. Barrier-effect comparison across dams will support removal of older and smaller dams on rivers (ex. Cape's Dam)
