To get a Staryu on Pokemon Sapphire, you should use the Good/Super Rod around the waters of Lilycove City. Just surf close to the shore with the rod and you should encounter a wild Staryu, after trawling through numerous Wailmers. Of course, you could always have one traded.
go to the safari zone (west of Lilycove City, the building behind the two trainers that are standing right next to eachother)If you go west you will find a lake. Phyduck will appear a lot but once in a while Staryu appears.Theres another lake if u head up but you need a mach bike. I Made the other answer!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! You fish on the east coast of Lilycove city with a Super rod.
The Pokémon in Sapphire who have the Illuminate ability are Volbeat, Staryu/Starmie and Chinchou/Lanturn.
You can't catch staryu in firered only in leafgreen or ruby or sapphire or emerald.
You can use either the good rod or super rod the super rod will work more often for finding staryu.
Staryu is one of them
You can't.

Depending on where you use it you can find various pokemon like Carvanha, Corphish, Sharpedo, Feebas, Staryu.
You can use either the good rod or super rod the super rod will work more often for finding staryu.
First of all it depends on what route your fishing in but you catch these pokemon: Magikarp, Staryu, Carvanha, Horsea, Psyduck, Goldeen.
I hope you mean "Staryu" when you say "satyru" since I'm basing this answer on the Pokemon Staryu. You need to use the Super Rod in Lilycove City. It's occurence rate is "common" so it should be pretty easy to capture.
You can't, because it's not available in that game. However, you can trade one from Ruby, Sapphire, Emerald, or LeafGreen.
Head to lilycove city and use the super rod in the water in the east part of the city keep hooking Pokemon until staryu appears then capture it.
