STUDIES ON LAMINARIA AND NEREOCYSTIS

A literature search on growth rates of benthic algae and invertebrates in Puget Sound showed relatively little is known about growth and productivity. Field studies were initiated to examine growth in populations of intertidal and subtidal Laminaria saccharina and subtidal Nereocystis luetkeana from Shannon Point, Puget Sound. Based on the movement of holes punched 10 cm from the stipe, maximum growth rates of JL. saccharina were observed during May and June (approximately 100 g wet wt. biomass per day). Evidence indicated growth also occurred beyond 10 cm from the stipe and that values must be considered conservative. 1981 MESA PUGET SOUND PROJECT NOS (National Ocean Service) Library Public Domain 1935
