How to access Instantiated GameObject's attached script's values?

I have a CrewSpawner.cs to instantiate crews available to hire, which works.

 crew = Instantiate(prefab) as GameObject;
             crew.name = "crew1";

The crews have a prefab with a component CrewStats.cs:

 using UnityEngine;
 using System.Collections;
 
 
 public class CrewStats : MonoBehaviour {
     public int fishingSkill;
     
     
     
     void Start () {
         fishingSkill = Random.Range(1, 11);
         
         
         }    
 }

How can I (from a 3rd script) access the instantiated's .fishingSkill? With

 public GameObject crew;
 public Text text;
 
 void Update () {
 crew = GameObject.Find("crew1");
         text.text = crew.name;
         }

I can get and display it's name, no problem but using crew.fishingSkills gives the error

 Assets/Scripts/ShowCrewSkill.cs(16,26): error CS1061: Type `UnityEngine.GameObject' does not contain a definition for `fishingSkills' and no extension method `fishingSkills' of type `UnityEngine.GameObject' could be found (are you missing a using directive or an assembly reference?)
 

16,26 is the fishingSkills part of crew.fishingSkills obviously.

When I type "crew." I already see that none of the CrewStats things are in the dropdown menu, nor is CrewStats itself, like so: crew.CrewStats. In the Inspector I can see the crew1 object's fishingSkill etc, so they do get created as planned.
