Abstract

THE River Tyne estuary is polluted by crude sewage and manufacturing effluents to such an extent as to cause a serious depletion in dissolved oxygen. It is not unusual to find a complete absence of dissolved oxygen on isolated occasions during the summer months. The number of normal estuarine organisms able to withstand these adverse conditions is very limited.1 Of these, Eurytemora hirundoides is the most abundant and the most hardy. Its region of maximum abundance lies between 9 miles and 13 miles from the river mouth, in the area of heaviest pollution and most noticeable oxygen depletion. At a survey held on July 22, 1925, it occurred plentifully in regions where the dissolved oxygen was nil, as determined by the Winkler method.1. 2 During 1929 I obtained it freely in the water sampler on occasions when the oxygen content was again nil (these remarks apply to the sampling depth of 6 ft.).
