Twohigh-speed plankton samplers (Gulf VII/PRO-NET and MAFF/Guildline) in use to samplepelagic eggs and larvae in waters around the UK are described. Both sample modificationsof Gulf III type samplers and are capable of being towed at speeds of up to 7 knots (3.6 ms^-1 ). The performance of the samplers (flow rates, degree of clogging of thenets and sample depth profiles) can be monitored during deployment. The real-timemonitoring packages also provide vertical profiles of temperature, salinity andchlorophyll a fluorescence. Both samplers can be constructed in different sizes to suitthe vessel from which the sampler is deployed and the expected concentration of planktonin the sampling area.
