Not sure if you can still get it, but I have a program called Resume Pro which had tons of examples you could use to modify to your specific needs. Just cut, insert, save. Actually made plenty of spare $ doing resumes for airline employees with it. Keep it short and sweet, but do try and make it professional, and don’t be a afraid to highlight anything you might think is relevant to the specific job you are seeking that will interest them. And we always added an “Objective”. I’d make it a bit more than “A position in the aquaculture industry” though. That’s just short of, “I want a job.”
From the looks of yours, you might want to get it done right for a fee. I’m thinking your cover letter may cause you some problems, as that’s what they would read first, b ut in the long run, it's the interview. Your going to get the job there, it's just getting the interview in the first place. Do what you can to get there.
