Call Server-Side Action

Hello,

I tried creating a server-side action and came across a weird issue. I tried checking online for solutions and am still stuck. Could you help me?

Lightning Component: TunaFishCheck.cmp

<aura:component implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes,force:lightningQuickActionWithoutHeader" controller="SeaFood" access="global">
   <aura:attribute name="tuna" type="Boolean" default="false"/>
    <aura:handler name="init" value="{!this}" action="{!c.tunaCheck}"/>
    <aura:if isTrue="{!tuna}">
        <div>true</div>
        <aura:set attribute="else">
            <div>false</div>
    	</aura:set>
    </aura:if> 
</aura:component>

function

tunaCheck: function (cmp){
        console.log('Its inside');
        var tuna= cmp.get("c.doAction");
        console.log('Check: ' + tuna);
        action.setCallback(this, function(response){
            var stateF = response.getReturnValue();
            alert("Check: " + stateF);
            if (stateF === 'SUCCESS'){
                component.set("{!v.tuna}", response.getReturnValue());
            } else {
                console.log('Unsuccessful return value');
            }
        });
        $A.enqueueAction(tuna);
    }

Apex Component

public with sharing class SeaFood {
    ApexPages.StandardController sc;
    public SeaFood(ApexPages.StandardController controll){
        this.sc = controll;
    }
    @AuraEnabled
    public static Boolean doAction(){
        PageReference refPage;
        Boolean fish = fishCheck()();
        if (fish){
            return true;
        } else if (!fish){
            return false;
        }
        return fish;
    }
    @AuraEnabled
    Public static Boolean fishCheck(){
        //censored functionality code
        return true;
    }

Note: while running,

console log shows: 

Its Inside 
Check: 
SecureAction: [object Object]{ key: {"namespace":"c"}

UI:

error while creating componenet for lightning component quick action [Action failed c:TunaFishCheck$controller$tunaCheck [action is not defined]]

Noticed that console.log('Check: ' + tuna); doesn't have a value

How can I fix these issues?
