Pokemon you can get with the good rod are: TENTACOOL, MARILL, MAGIKARP, CHINCHOU ( under-water ) and CORPHISH.
Sapphire is better, but yes, emerald is good.
Raltz! :D
Torchick is a good Pokemon if you train it right anything should work
i just used Adore Pokemon and she gave me a lum berry

Kyogre
if you took mudkip, you should be set just by using Marshtomp's water gun, but if not, a water type ALA wingull or a ground type out of the desert over there (trapinch, sandshrew) could be good options I used Geodude and the attack i used was magnitude
Sapphire is better, but yes, emerald is good.
Snorlax
water, leaf, fighting, psychic, electric, there are a few good normal Pokemon too. if these are not available try and stick with electric and water
The Good Rod in Pokemon Emerald is found on Route 118. If the player uses Surf from Mauville City to cross Route 118, there is a fisherman on the other side of the water will hand over the Good Rod.
Linoone (It can learn nearly all of the HM's)
Well, there isn't really any ''good'' water Pokemon. Legendaries are always strong, and a great one is kyrogue, which you can get in Pokemon emerald. It really all depends on which moves the Pokemon knows
yes he is probably the best pokemon in pokemon emerald
Raltz! :D
i think sableye or a gyarados that knows a good water move i think a good lvl 60+ blazikin
