The mortalities and contributing parameters were estimated for key species discarded during commercial gillnetting (80-mm mesh) targeting dusky flathead Platycephalus fuscus in a southeastern Australian estuary. Bycatches (1470 individuals from 16 species over 11 deployments) were assessed for their immediate mortalities onboard the gillnetter, before subsamples (570 individuals from 11 species...

In Benin, the tarsonemid mite Polyphagotarsonemus latus (Banks) (Prostigmata: Tarsonemidae) is a key pest of gboma eggplant Solanum macrocarpon (L.) (Solanales: Solanaceae), a leafy vegetable on which it causes considerable damage to the plants and substantial reduction in yield. Predatory mites in the family Phytoseiidae have been successfully used in the biological control of numerous agricul...

Monthly fish samples were collected from one location at Shatt Al- Basrah Canal July 2008 to June 2009, using coastal seine net of dimensions 80 m length and 8 height with a mesh size 10×10 mm. Water temperature, salinity water transparency measured. Fishes identified in the laboratory total lengths weights Catch per unit effort was estimated for 22 species during sampling period. The biotic fa...

Field survey of Aquaculture farms in Basrah governorate was done during 2007. The study showed that there are 80 fish farm with total area 773.5 donum, while it 16 2003. 75 % the were less than 25000 m² (10 donum). 53.9 excavated pond, 34.2% concentration by half ground pools and 11.8 dyke pond. About 87.5 using pump 12.5 used tidal current for water supply. This 95 fishes source from Marine Sc...

In response to concerns over excessive discarding from Australian recreational round traps (with four funnel entrances) used to target giant mud crabs, Scylla serrata, an experiment was done to assess the independent and cumulative utility of paired, bottom-located horizontal escape gaps (46×120 mm) and increasing mesh size (from 51 to 101 mm). Compared to conventional traps comprising 51-mm me...
