Nutritional changes in Traditionally Preserved Shellfishes from the Niger-Delta, Nigeria

An Evaluation of Three Fish Diets Formulated from Locally Generated Agricultural By-products for Catfish (Heterobranchus bidorsalis: Geoffroy St. Hilaire, 1809) culture

“…Work done elsewhere (Eze et al, 2000;Nwosu et al, 2002;Nwosu et al, 2009) demonstrated that fish growth is proportional to the amount of protein in the diet. It is noteworthy also that although all three fish diets used contained protein only T1 contained fish protein which is a high grade protein (Egwui, 1986;Ockiya et al, 1995;Eze et al, 2000;Nwosu et al, 2002 andOkeke et al, 2016).…”

“…Various research work (Alfred-Ockiya et al, 1995;Eze et al, 2000;Nwosu et al, 2002;Jamabo and Alfred-Ockiya, 2008;Nwosu et al, 2009 andOkeke et al, 2016) have aptly demonstrated the growth response of cat fishes to agricultural by-products such as proteins sources. This, therefore, formed the pivot of the present research work viz: to evaluate three fish diets formulated from locally generated agricultural byproducts for catfish culture.…”

Genetic Study of Some Egyptian Crabs Species in the Fisheries Grounds

“…It is worth to mention that Portuns pelagicus is one of the commercially important crabs along the Parangipettai coast and has a great demand for their esteemed seafood delicacy and also the value of fishery they support. They are heavily exploited from the Parangipettai coast due to their high demand in local and foreign markets (Alfred-Ockiya, 2000).…”

“…Although all large crabs species are edible, most marine crabs of commercial importance belong to three families: Portunidae (swimming crabs), Xanthidae (mud crabs) and Cancridae (cancer crabs). In most West African countries, crabs are an important source of animal protein for coastal and riverine communities; hence most published works deal with their nutritional composition (Alfred-Ockiya, 2000;and Oduro et al, 2001) and ecology (Okafor, 1988 ;Lawal-Are and Kusemiju, 2000). Few studies were carried out on their morphometrics, although this resource has been exploited locally (Anetekhai et al, 1994).…”
