In onDialogResponse you only have 1 dialogid named "FISH_DIALOG" but you are showing players a dialog with the id "FISH_DIALOG+1/2/3/4" so when they respond, the function won't find any "FISH_DIALOG+1/2/3/4" in OnDialogResponse. Try to remove those numbers and let just FISH_DIALOG.

public OnDialogResponse(playerid, dialogid, response, listitem, inputtext[])
{
    if(dialogid == FISH_DIALOG)
    {
        if(response)
        {
            switch(listitem)
            {
                case 0:
                {
                  new string[300];
                  format(string, sizeof(string), "Buy Baits | Cost: %d", BaitCost);
                  ShowPlayerDialog(playerid,FISH_DIALOG, DIALOG_STYLE_INPUT, "Fish Market", string, "Buy", "Cancel");
