CHAPTER ONE

1.0 INTRODUCTION

Seafood possesses of myriad of benefits to the human health. For example, the vital nutrients contained in seafood are important in the development of the brain and nervous system. Apart from this, the nutrients found in seafood are known to have anticancer effects (Liao and Chao, 2009). In many developing countries, seafood has helped to alleviate food shortages, offering a valuable complement to a healthy and nutritious diet. The worldwide consumption of seafood has steadily increased in recent years (FAO, 2010). Since there is a clear diet-CVD correspondence as evidenced both by experimental and epidemiological reports, dietary interventions containing marine food might be of aid in disorders such as atherosclerosis. Moreover, seafood has a great influence on health promotion and maintenance (Mozaffarian and Rimm, 2006). Seafood is healthy due to its high content of omega-3 PUFAs, mainly docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) (Dyerberg et al. 2000).

Seafood comparies all bony fishes and the more primitive sharks, ray sawfish, sturgeons, and lamprey; crustaceans  such as lobster, crabs shrimps, prawn and crayfish; mollusk including clams, oysters, cockle, mussels, periwinkle, whelks, snail, abalones, scallops, and limpets; the cephalopod mullusks- squids, octopus and cuttlefish, edible jellyfish, sea turtle, frog, and two echinoderms sea urchins and sea cucumbers.

The most commercially important ocean fish are species of Salmon, herring, codfish, flatfish, flounder, sole, habitat, turbot), redfish (ocean perch), jack mackerel, tuna, and sardine major species of fresh water fish are carp, eel, truot, white fish, pike, pike perch, and cat fish. The catch ranges in size from white bait and bay ell, both about 5cm (29 inches) long to Bluefin tuna, up to 4.3 metres (15 feet) in length (Britannica, 2022).

Periwinkle (Tympanotarus fuscatus) is the a relatively cheap source of  animal protein and is mostly consumed in the South East of Nigeria and some riverine areas of west Africa. Mollusca are generally soft bodies animal that contain external skeleton shell. Some mollusk are found mostly in shallow waters and sometimes in inter-tidal zone where they burrow into beds of the rivers thereby served as their habitat and they feed majorly on algae and diatoms. Periwinkle is commercially valuable in the Niger Delta area of Nigeria. The value compare favourably with those of domestic livestock and fish. Considering the enormous commercial, nutritional, and industrial importance of periwinkle. The fish industry cannot continue to remain neglected also, with the current rate of population increase, there would be a need foe small snail meat substitution so as to prevent their extinction due to consumption.

Hence, it is expedient to create awareness to the people about high population of nutrition indices of periwinkle consumed in Nigeria. Periwinkle meat is domestically used as human food, livestock feed and the shell can be as ornament for decoration and painting.
