NGO working to improve the welfare of shrimp through increasing the oxygen in tanks

C'est ce que Shrimp Welfare Project recherchait dans leur logo design

I want to create a logo for a NGO focusing on improving the welfare of farmed shrimp. Ideally it will look serious and abstract. It should definitely NOT look like food and NOT be curled up in a C-shape. I've attached what we have now and an idea which is in the general direction of what we like. It should be modern, slick and minimalistic. It should have sans serif fonts. Color scheme should be professional blue/green (ocean water style). Our programme consists of improving the oxygen in the water that shrimp live so, to the extent possible, include somehow oxygen in the water as part of the logo (if it looks good). FYI, I'm not a huge fan of the logo we have at the moment (which I've attached). Voir plus
