My 1st skill guide hope it helped, heres the numbers and some notes and numbers:
------------------------
Heres a quick run through

1-15 Meat,chicken and crayfish
15-52 Trout
52-58 Pike
58-63 Salmon
63-70 Tuna
70-86 Lobster
86-90(99 if f2p) Swordfish
90-94 Monkfish
94-99 Shark
-----------------------
Prices will change, shouldnt change to much
Each lobster gives 120xp
you also loose per lob 85gp per lobster

Each swordfish gives 140xp
you also loose 75gp per swordfish

Each monkfish gives 150xp
you also loose about 60gp per monkfish

Each shark gives 210xp
you also loose about 110gp per shark

Without using the techinque doing it the normal way, you
can cook around 1200 an hour

so with lobs its 144k xp an hour
and with swordfish its 168k an hour
monkfish 180k
shark 252k

using the method i seem to cook about twice as fast
so with this method i can cook around 2000-2400 an hour
with lobsters thats up to 288k xp an hour
with swordfish thats up to 336k an hour
with monkfish thats 360k an hour
and with shark thats 504k an hour
numbers are excluding that you dont have to light your own fires

now with this method its best to be in fixed mode to get the right click
and cook it easier that way, and when you first start doing this
your gonna screw it up alot, sometimes to the point where you are better off
just doing it normally, but once you get used to it its well worth it
in f2p this is the best place to cook, but in members you want to cook in
the rogues den or cooking guild
