Fresh monkfish are caught during Swan Song. Fresh monkfish heal 200 life points when successfully cooked and then consumed.
During the quest, Arnold Lydspor asks players to refill the fishing colony's food stocks. Players must catch and successfully cook five fresh monkfish. Catching a few extra in case some burn while cooking is not a bad idea, as even players with 99 cooking may burn them. However it is not recommended that players train Fishing during the quest, since these quest-specific raw monkfish provide much less experience for catching and cooking until the quest is complete. If eaten, it says "It's so fresh it's got no flavour, and it doesn't heal many life points either."
Like regular monkfish, players need a Fishing Level of 62 to catch fresh monkfish, but using fishing potions at Level 59 is possible. An Admiral pie also works at Fishing level 57. A spicy stew can be used to boost from 56, but it isn't recommended, since it has a chance of lowering Fishing level by six.
