ABSTRACT
Food is inevitable in ones life and fish is a main source of vitamins and protein in ones life. Fish pond is a place for growing fish for commercial or private needs or gestetic purpose. The design of fish pond is very important because of its aqueous retaining nature which if there is leakage will not only cause loss of water but also loss of lives of fish and plants in it. A adequacy and accuracy is relevant in the design of fish pond. The engineer is bordered with the functions of designing, construction, maintenance, administration and/or operations of a fish pond. Fish pending creates sobs, provides foods, and can also serve some a estetic works. This project can serve as a reference material for those carrying out the same or related project works or to a practicing members of the community who is faced with the problem of fishpond design. BS8110 and Bs8007 are the reference codes for this project work while project procedures are sourced from many other reliable sources named at the appendix.

CHAPTER ONE
INTRODUCTION
Design of fishpond need accuracy which must be from the onset (location of the site) till the end of construction including proper management.
Volume of area of fishpond required is determined using the number and type of fish to be grown inside. It is also advisable to allow for more space than calculated.
Situation of a fishpond should be done in such a way that is receives light or not in a perpetual shade. It is not recommended to be under a tree because of the fallen leaves.
TYPES OF FISHPOND Â
Fish ponds can be done in many ways or classified in many ways:-
- It may be buried to the brine allowing only the freeboard to be above the ground or;
- It may be built above the ground level except for the buried base.
The latter is more advisable to allow for exchange of water periodically.
Others can be cast with concrete; the depth of every fish pond is dependent on the type and area of fish pond.
In cold regions the depth of fishponds is advised to be above 900mm while a minimum of 600mm is taking in hot regions.
