"Instead of picking out individual microscopic animals from a plankton net
, you take the entire net contents, grind it up, and get back, say, hundreds of thousands of barcode sequences," Govindarajan said.
Abstract--To assess larval fish and egg extrusion through the standard-size mesh plankton net
used during resource surveys of the Southeast Area Monitoring and Assessment Program (SEAMAP), 81 bongo tows with side-by-side nets, each constructed with a different mesh size (0.333 mm and 0.202 mm), were taken during 5 SEAMAP surveys conducted in the Gulf of Mexico during 2005-2007.
Many hauls of plankton net
can be necessary, and a large volume of filtrate sample can be useful.
The sample containing Solmundella bitentaculata was collected 52.5 km far from Para's coast, (0[degrees]01'0.6"N, 47[degrees]57'48.4"W), on April, 2013, by oblique trawling along the water column, from the bottom to the surface, using a 200 [micro]m cylindrical-conical plankton net
. The water average temperature was 29[degrees]C, salinity 19.7 and maximum depth of 16 meters.
Amoebae testate associated with aquatic macrophytes samples were obtained by dragging graduate bucket (13 L) in the rooted marginal vegetation (five times), totaling 65 L, and then filtered in a 20 [micro]m-mesh plankton net
. Plankton samples were collected with graduate bucket (13 L) dragged at the center of the stream channel (10 times), totaling 130 L, and then filtered in a 20 [micro]m-mesh plankton net
Ctenophores collected by gentle plankton net
tows were transported to the laboratory within 12 hours.
shelf ecosystem has been plankton nets
. However, plankton net
surveys from 1977 to the present only record a very small number of observations of ctenophores (less than 2% of all tows taken).
Additionally, plankton was caught with a 15 [micro]m pore-sized plankton net
and sediments were taken next to the wormsnails' in situ habitat.

(150 [micro]m mesh size; e.g., Bigelow Laboratories)
Zooplankton were sampled using a 500-[micro]m Nitex mesh, 0.5-m mouth diameter, conical plankton net
(see Peebles et al.
Plankton samples were collected the d of each feeding from a local pond with a student plankton net
(2 mm mesh, BioQuip), and consisted primarily of cladocerans.
