It goes without saying that you'll need to make sure the animals you buy are fertile, too. Keep in mind that you'll also need to keep Researching the animals you find and some might not start breeding until you've reached a certain Research point. Animals won't age while they're in storage, which means you won't run the risk of your new friend dying before a mate is found. If you buy a female animal but a male of the species is not available yet for breeding with, keep the single animal in storage. The best starter animals are the likes of Warthogs, Tortoises and Ostriches as they sell reasonably well and breed pretty quickly. You won't get any Conservation Credits by selling animals bought for cash but you can earn them by trading their young and fertile offspring. Some animals in Franchise Mode can be bought for cash and others for Conservation Credits. To keep the cash flow going, remember to place lots of Donation Boxes and make sure items like hats, balloons and toys are affordable for the public. Starting with a small zoo filled with fast-breeding animals is the way to go here, so you can continuously sell your animal's offspring for a few years to earn Conservation Credits easily. Say hello to other players that visit your zoo when notified.Sell animals in Franchise Mode or release them.
Visit other zoos, anonymously or otherwise.The easiest way to earn Conservation Credits is: If another player visits your zoo, you'll get a notification in-game alerting you to their presence. You can also visit other zoos anonymously, though it'll be your avatar that visits. If you click on My Zoos you'll be able to see your franchises as well as any zoos you've subscribed to. You can only visit a zoo in person if you subscribe to their zoo via the Plant Zoo Steam Workshop by clicking the button on the screen. Click on it and check the Visiting Status which allows your franchise to become visible to other players, as well as giving you the option to visit other zoos. Once you've picked a suitable name for your zoo, you'll see an Edit button to the next beside your franchise's name. To visit other zoos, you'll first need to create a zoo in Franchise Mode. When you first log in to Planet Zoo, you can create an avatar and choose your local region for your avatar's base. Change the 0 to a 1 and you finished the research.Conservation Credits allow you to buy all sorts of sweet animals in Planet Zoo, and the easiest way to earn them is by popping along to a friend's zoo to check out the competition. Change the value type bottom right to byte then there is a 0. There should pop up 1 address for each stage. Then start a technology research (can take some time). I found a address for research, its "PlanetZoo.exe"+5DD395E right click and do "Find out what addresses this instruction access". I highly doubt all the animals would have their stats stored server side, especially the offsprings of the original animals. The research done are also serversided for franchise mode IIRC.
The Conservation Credits in franchise mode are also server-sided I haven't found anything related to genetics. Yia I looked for some Tables/Trainers in the internet. The problem for me is that there is no way to change the genetics of an animal when it is still alive and there is no way to see the exact numbers of its genes. Yeah, I was looking to figure out a way for this.
