Hmmm my dear friend permaculture is a form of agriculture that tries to copy and simulate the structure of flourishing ecosystems. You create a perfect co-operative environement between different plants, microorganisms and animals and let it provide you food. Plants help each other, and animals, clear bugs and insects that harm the crops. no fertilisers and no pestisides used.
Acuaculture is just having fish in cages and feed them, and is usualy creating high pollution and spread diseases to wild fish. Here in greece they have created many problems to our ecosystem leading to a huge drop in wild fish, and sea mammals population. They have also destroyed many beatifull beaches.
I would suggest you trying sth else
