A survey was carried out in all the twenty three (23) Local Government Areas of Rivers State to evaluate the different methods of fish preservation in the State. The required information was collected by the use of questionnaires and direct interviews with the fish farmers and traders. The study holds that gender difference influenced approach to fish business, and that respondents are faced with problems which include lack of record keeping and finance. Others are inability of the State Government to introduce modern methods of fish processing/preservation techniques and proper management of fish business. If these innovations are introduced to farmers, there will be improvement in production, curtail spoilage and boost fish preservation in Rivers State.
