Zooplankton of Wellington Harbour, New Zealand
[introduction]
The plankton fauna of Wellington Harbour discussed in this study can be divided into two sections as described below.
The numerical abundance of the species discussed is based on the data presented in Text-fig. 7. All quantities may be equated with a single 20 minute horizontal plankton tow with a 36 gauge two foot diameter cone net at depths between one fathom and six fathoms. The numerical equivalents of the expressions "rare", "few", "common", "very common", abundant" and "very abundant", lie within the ranges set down in the key to Text-fig. 7. When the above expressions have been used in this sense they have been italicised.
