Why can't I pass an array reference to another array variable?

So I wrote a simple ObjectPooling script that has just an array containing the objects I want to use. Problem is that I created another script called TestPool that recieves a reference of the array created in the ObjectPooling script and it does not work. Here is the ObjectPool script:

    `[HideInInspector] public GameObject[] sharks;

 public int numberOfObjectsToCreate = 35;

 // Use this for initialization
 void Start () {
     sharks = new GameObject[numberOfObjectsToCreate];
     InstantiateSharks();
     //Debug.Log (sharks.Length);
 }
 
 // Update is called once per frame
 void Update () {
 
 }

 private void InstantiateSharks(){
     for(int i = 0; i < numberOfObjectsToCreate; i++){

         if(i <= 7){
             sharks[i] = Instantiate (Resources.Load ("Prefabs/Sharks/OpenMouthShark")) as GameObject;
             sharks[i].SetActive(false);
         } else if(i <= 14){
             sharks[i] = Instantiate (Resources.Load ("Prefabs/Sharks/BossShark")) as GameObject;
             sharks[i].SetActive(false);
         } else if(i <= 21){
             sharks[i] = Instantiate (Resources.Load ("Prefabs/Sharks/CloseMouthShark")) as GameObject;
             sharks[i].SetActive(false);
         } else if(i <= 28){
             sharks[i] = Instantiate (Resources.Load ("Prefabs/Sharks/BioShark")) as GameObject;
             sharks[i].SetActive(false);
         } else
             sharks[i] = Instantiate (Resources.Load ("Prefabs/Sharks/SkeletonShark")) as GameObject;
             sharks[i].SetActive(false);
     }
 }

}`

and the other script:

 using UnityEngine;
 using System.Collections;
 
 public class TestPool : MonoBehaviour {
     public GameObject[] shark;
     public ObjectPool objpool;
 
     // Use this for initialization
     void Awake(){
         objpool = GameObject.Find("ObjectPool").GetComponent<ObjectPool>();
 
         shark = objpool.sharks;
     
         Debug.Log (shark.Length);
     }
 }
 

The line "Debug.log(shark.Length);" is supposed to return a value other that 0, but it does not...

Please Help me!!!
