How do sea-run fish connect ecosystems?

Scientists from the NOAA Fisheries science center, the  Greater Atlantic Regional Office, and the Smithsonian Environmental Research Center developed a conceptual model to investigate the ecological role of sea-run fish and the connections they make among different ecosystems. The goal of this work is to improve ecosystem services delivery, ecosystem resilience, and the productivity of the sea-run fish community.

  1. Yet another study, another report…..

    Suggest the team look at this 2-part piece of non-scientific, general interest Scottish televsion about River Spey from source to sea. The world-famous salmon river is still flowing as fast and looking as lovely as it ever did, but lacks its once great numbers of Atlantic salmon, fish that even Britain’s new King Charles III caught in his schooldays (as you will see in the second episode). Everything still present and correct, it appears, except the salmon of past years.

    Part 1 pf the Spey –

    Part 2 (Episode 3) –

    PS -Tip to Scientists: Look to fast-melting Arctic ice and warming seas, plus a lack of smal, marinel food fish etc for the young salmon, if they manage to haul their little fishy asses up to the northern feeding grounds, as a major reason for missing salmon. You can improve a river all you like, remove all of its infant and adult salmon-predators too, but if the seas and the climate themselvwes are f—ed…..
