Ichthyoplankton Surveys using Bongo Nets
Plankton nets, each 57 cm in diameter and 3 metres in length are used to capture pelagic fish larvae. Ichthyoplankton survey methods and field gear are described in the following reports:
- Larval eulachon surveys in BC's central coastal inlets: CSAS 1999/177
- Ocean and river, ichthyoplankton sampling manual: Tech. Report #2451
- British Columbia larval herring surveys and stock structure: 1985-1997
- Fish larval Identification assistance is provided by the Alaska Fisheries Science Centre.
- Pelagic fish larvae, fish farms and lights: Aquaculture update #93, MS #2662 and Tech. #2634
- Ichthyoplankton surveys: Strait of Georgia herring and Strait of Georgia hake/pollock.
- Fraser River eulachon egg/larval assessments. Juvenile growth and offshore distribution.
