Chemometric estimation of captured Farfantepenaeus notialis, Pérez-Farfante 1967 (Crustacea: Penaeidae).

Background: Chemometrics can be used to analyze a wide range of food products for authentication, quality control, differentiation and the determination of nutrition quality. Owing to the scarcity of studies relating to the intrinsic physico-chemical characteristics of penaeid shrimps caught on the Nigerian coast, the aim of this research was to estimate the energy-supplying nutrients, mineral elements and functional characteristics of Farfantepenaeus notialis from the Lagos Lagoon.

Methods: The proximate composition was determined using the AOAC method while the energy-providing nutrients were multiplied by the Atwater factors.

Effect of salinity on survival and growth of blue crab, Callinectes amnicola from Lagos Lagoon, Nigeria.

The effect of salinity on the survival and growth of Callinectes amnicola (De Rocheburne) from the Lagos Lagoon, Nigeria was monitored in the laboratory for 22 weeks. The crabs were euryhaline and tolerated a salinity range of 5 to 25 per thousand and had 90% survival at 15 and 20 per thousand. The highest gain in weight (173.
