Abstract

We are making this project because we wanted to investigate and at the same time help people in the future with any issue they could have by feeding their production of Tilapia fish for sell. As we know Tilapia fish is one of the greatest sources of food and sell in Honduras, people especially the actual and future producers of Tilapia hatcheries. Why? If they know how to feed their fishes they will have a good product, people will buy their fishes and have a greater entry above any other producer. Tilapia fish is found in any supermarket in Honduras people always buy the biggest fish so feed well the fishes will change today business increasing their entry too. The actual problem is which of all fish food will cause that the fishes increase their size. The three most famous foods for Tilapia fish are (concentrate, lettuce and normal fish food) and we didn’t know which food really work the best, but since the beginning we build up the hypothesis that concentrate will be better than any other fish food in the market because of the ingredients, they seem to be great to the consume of the Tilapia fish.in order to solve this problem that not we put in front also many producers in their time had pass by and even today they still don’t know how make their fishes grow more to have a better entry and keep their work or source of incomes we decided to do this project by buying three tilapia fish all of them the same size and conditions to reduce the percentage error by creating three fish bowl and fill  them with 10liters each bowl the same conditions were for each tilapia fish also to reduce the percentage error we gave oxygen to the fish with a pump we measured each fish the first day and during the last 2 weeks we feed them each with the same amount of food 1.5grams per day. Every two days we measured each Tilapia fish to see which is actually growing more. Our results were awesome from the three tilapia fish the one we feed with concentrate gain the length of twelve cm this means it grow five cm in two weeks was the fish that grow the greatest. This results help determine that our hypothesis was correct and Fish concentrate did make Tilapia fish grow more than any other fish food.

Introduction

For many years farmers have made hatcheries of tilapia fish, this give them an economic income by selling their adults tilapia fishes which are the ones who growth bigger, by having the correct way of feeding your tilapias, farmers will have their income faster than how they were doing before.

Background Research

Tilapia has become the third most important fish in aquaculture after carp and salmon; worldwide production exceeded 1,500,000 metric tons in 2002 and increases annually. Because of their high protein content, large size, rapid growth (6 to 7 months to grow to harvest size), and palatability, a number of tilapiine cichlids—specifically, various species ofOreochromis, Sarotherodon, and Tilapia—are the focus of major aquaculture efforts.

Tilapia fisheries originated in Africa. The accidental and deliberate introductions of tilapia into Asian freshwater lakes have inspired outdoor aquaculture projects in various countries with tropical climates, most notably Honduras,[4] Papua New Guinea, the Philippines and Indonesia. Tilapia farm projects in these countries have the highest potential to be "green" or environmentally friendly. In temperate zone localities, tilapia farmers typically need a costly energy source to maintain a tropical temperature range in their tanks. One relatively sustainable solution involves warming the tank water using waste heat from factories and power stations.

Tilapiines are among the easiest and most profitable fish to farm due to their omnivorous diet, mode of reproduction (the fry do not pass through a planktonic phase), tolerance of high stocking density, and rapid growth. In some regions the fish can be raised in rice fields at planting time and grow to edible size (12–15 cm, 5–6 inches) when the rice is ready for harvest. Unlike salmon, which rely on high-protein feeds based on fish or meat, commercially important tilapiine species eat a vegetable or cereal-based diet.
