Fisheries Minister Ken Baston said Prawn Watch was an exciting citizen science project linked to the Western School Prawn restocking program which was focused on restocking the Swan and Canning rivers with prawns.
As they are a vital part of the Swan and Canning rivers ecosystems, it s important we understand the Western School Prawn s role and the cause of their decline, Mr Jacob said.
The project has already released more than 635,000 juvenile Western School Prawns into these rivers and will investigate the distribution of prawns and the factors limiting the prawn stock, Mr Baston said.
ABSTRACT The school prawn (Metapenaeus macleayi) is important among commercial prawn trawler operators, but its harvest is affected in a complex way by a number of interacting water quality, and other variables.
In Australia, school prawn (Metapenaeus macleayi, Haswell) occurs along the east coast of Australia.
The impact of river discharge on distribution and production of the school prawn Metapenaeus macleayi (Haswell) (Crustacea: Penaeidae) in the Clarence River region, northern New South Wales.
Burrowing, feeding, and spatial distribution of the school prawn Metapenaeus macleayi (Haswell) in the Hunter River region, Australia.
Bycatches were comparatively low in both experiments and, in addition to juvenile school prawns (approximately 9% of the total school prawn catch in each river), mostly comprised fish <200 mm total length, such as yellowfin bream (Acanthopagrus australis), southern herring (Herklotsichthys castelnaui), silver biddy (Gerres subfasciatus), and narrow-banded sole (Aseraggodes macleayanus).
Abstract--The potential for changes to onboard handling practices in order to improve the fate of juvenile school prawns (Metapenaeus macleayi) discarded during trawling were investigated in two Australian rivers (Clarence and Hunter) by comparing a purpose-built, water-filled sorting tray against a conventional dry tray across various conditions, including the range of typical delays before the start of sorting the catch (2 min vs.
2006) observed that the short-term (three days) mortality of juvenile school prawns was reduced from approximately 35% during conventional sorting to about 16%, simply by holding them in water-filled containers.
We sought to use this approach to assess the water tray for reducing the mortality of discarded school prawns in the Clarence and Hunter rivers.
