Is your terrace just lying empty? That space could be your secret to a new income stream. Here’s a solid business idea that lets you earn up to a lakh, right from home and without a huge investment.<img>Most of us think a business needs big money and an office. But what if you could earn well right from home? A fantastic idea is using your terrace for fish farming. Many homes have empty terraces that people only use for a few plants or just leave vacant.<img>You can easily turn this empty space into a small business for extra income. In cities where land is scarce, terrace fish farming is a great option many are trying out. It’s simple to start. Just set up a few fibre or cement tanks on your terrace and fill them with clean water.<img>Next, you just add the baby fish, called fingerlings. All you need to do is feed them daily and keep the water clean. You can start with just 4-5 tanks even in a small space. Farming Murrel fish is especially profitable because it’s in high demand. One kilo of Murrel can sell for up to ₹400, and hotels and markets are always looking for it.<img>You don’t need a huge initial investment. You can kickstart this business with about ₹1.5 to ₹2 lakh. Many banks even offer loans for this kind of project. With good planning, you can get a harvest every six months. A single successful season can help you earn up to ₹1 lakh a month. It’s a fantastic way to make money without leaving your house.
