A fish farming business in Kenya started with one Facebook order for 10,000 fingerlings. Blue Marine Investments now operates farms, trains farmers, and runs a restaurant.

Fish Farming Business Started with Single Facebook Order Now Thrives as Blue Marine Investments

Peter Njoroge Ngugi, 30, studied for a diploma in 3D animation and graphics design. He used to operate a business in Kenya, but when it ran into difficulties, he was forced to shut it down. He found himself jobless with no clear path forward. He decided to try aquaculture, and the venture he built is now his source of livelihood.

He is the founder and chief executive of Blue Marine Investments, a company focused on aquaculture production. He runs several fish farms with his wife Lynne Wambui Mungai, 25, who holds a BSc in biochemistry from Kenyatta University and serves as the company’s COO.

How it all began

It all began one morning when Peter found himself jobless, having just closed down his previous business. He used to collect and sell glass bottles to recycling companies that specialised in producing glass packaging for beverages. Unfortunately, when these companies significantly reduced their buying prices, the business was no longer sustainable, and he was forced to shut it down.

While wondering what to do next, he started scrolling through Facebook to see what opportunities were out there. That is when he came across a post from a foreign national living in Nanyuki, who was looking to buy tilapia fingerlings. Without hesitation, he commented that he had them available. The buyer quickly responded, saying he needed 10,000 fingerlings.

Peter immediately contacted a few local suppliers he found online. By good luck, he came across one selling fingerlings for Ksh5 each. He called back the buyer and quoted a price of Ksh15 per piece, requesting a deposit to secure the order. The buyer promptly sent a deposit of Ksh50,000, which Peter used to purchase the stock.

Within two days, he delivered the fingerlings and made a profit of Ksh100,000. Encouraged by the success, he started posting about fingerlings on local online marketplaces. In his second week, he received another order and made a profit of Ksh35,000. That is when he realised there was a serious gap in the market and a growing demand for quality fingerlings.

He decided to officially register his business under the name Blue Marine Investments.

Growth over five years

Over the years, the company has leased several fish farms across different regions, all operating under the name Blue Marine Fisheries Kenya. In the five years since, the business has grown to cover three main areas: fingerling production, farmer training, and grow-out.

The fingerling production ensures a steady supply of quality fish seeds for farmers. The training component helps farmers understand best practices in aquaculture. The grow-out operations demonstrate what is possible with proper management.

Creating a ready market

To create a ready market for the farmers they supply, the company opened a fish outlet in Ruaka called Blue Marine’s Kitchen. They plan to open similar outlets in other major towns. This ensures that farmers have a reliable place to sell their harvest.

The company has also introduced a buyback programme. They purchase mature fish from farmers who initially bought fingerlings from them. They then supply the harvested fish to local restaurants and provide home deliveries. This creates a complete value chain from fingerling to plate.

A model for other agripreneurs

Peter’s story is a powerful example of how opportunity can come from unexpected places. A single Facebook post, a quick response, and a willingness to take a risk led to a thriving business. Today, Blue Marine Investments is a testament to what is possible when determination meets opportunity.

The business is also a family affair. Peter and his wife Lynne work together to manage the growing enterprise. Their complementary skills, Peter’s business acumen and Lynne’s scientific background, have proven to be a winning combination.

What farmers can learn

Peter’s journey offers several lessons for aspiring agripreneurs. First, opportunities are everywhere if you know where to look. Second, even a small order can lead to something much bigger. Third, building relationships with buyers is essential. Fourth, diversifying into training and marketing creates stability.

The fish farming business in Kenya is still growing. Demand for fish is rising. Farmers who enter the sector now can build sustainable businesses. Peter Njoroge Ngugi has shown that with the right approach, aquaculture can be profitable.

The fish farming business from Facebook order is a story of resilience, innovation, and hard work. It is proof that age is not a barrier to success. It is proof that even a jobless day can be the beginning of something great. Peter took a chance, and it paid off. His story inspires other young people to look at agriculture differently. It is not just about farming. It is about building businesses. It is about creating opportunities. It is about feeding the nation. And it all started with one Facebook post.
