Carbon and nitrogen flow, and trophic relationships, among the cultured species in an integrated multi‑trophic aquaculture (IMTA) bay

Stable isotopic signatures of organic carbon (δ13C) and total nitrogen (δ15N) were measured on suspended particulates and sediments in order to understand the sources of organic matter (OM), water quality and flow of organic carbon and nitrogen among integrated multi-trophic aquaculture (IMTA) speci...
