The importance of collagen and gelatin has been increasing recently due to their wide applicability in various fields. Marine organisms provide promising alternatives as both collagen and gelatin sources compared to their traditional bovine and porcine counterparts due to better properties, high abundance, and health and religious reasons. In this research, collagen and gelatin were acid-extracted from the skin of Yellowstripe fish (Selaroides leptolepis) with the addition of Ethylenediaminetetraacetic Acid (EDTA) and pepsin enzyme. Fourier-transform infrared spectroscopy (FTIR) showed that all as-extracted products contain all characteristic functional groups of collagen or gelatin. The addition of 5 wt.% of Pepsin increased the yield of collagen and gelatin to the optimum values of 7.19 wt.% and 3.57 wt.%, respectively. Ethylene Diamine Tetra-acetic Acid (EDTA) pretreatment successfully lowers the mineral content down to 0.27 wt.% for collagen and 1.39 wt.% for gelatin. The Yellowstripe fish collagen and gelatin were stable until the denaturation temperature of 59.90℃ and 74.66℃.

“…Sea-foods are defined as the various living organisms found in the ocean and are classified into two; shellfish (e.g. oysters, missile, lobster, prawn, crabs and shrimp) and fish [1]. It is an excellent source of protein and its low calorific value makes it a healthier alternative to red meats or poultry as it is also rich in vitamins A, E, C and D as well as calcium (Ca) and iron (Fe) [1].…”

Crayfish (Decapoda reptania) have their skeleton on the outside instead of the inside and it's called an exoskeleton and this outer skeleton is one of the features that give shrimp their unusual look [2].…”

Heavy metals are elements that contaminate seafood and make them harmful to human health when present in quantities that are higher than the permissible limit. This study was conducted to determine some heavy metals such as lead and mercury contained in dried crayfish gotten from three different locations (Oron, Ataba and Nembe town in Akwa Ibom, Rivers and Bayelsa State respectively) and sold in the Creek Road Market, Borokiri, Port Harcourt, Rivers State. The dried crayfish samples were purchased randomly from marketers in the market. 5g of the dried crayfish samples with its different organs (Gills, muscle tissues) were ground into powdered form and digested with HNO3 using standard procedures and analysed for lead and mercury using the micro plasma atomic emission spectrophotometric analyser. The results showed that Lead content in the dried crayfish from Oron, Ataba and Nembe were 0.140 ± 0.014 mg/kg, 0.040 ± 0.014 mg/kg and 0.016 ± 0.002 mg/kg respectively while for Mercury content, Oron crayfish contained 5.136 ± 0.017 mg/kg, Ataba 3.744 ± 0.017 mg/kg and Nembe 3.948 ± 0.023mg/kg. The mean values in the three different crayfish samples were significantly different (p<0.05). This result shows that the lead content present in the dried crayfish are within the permissible limit of 1 mg/kg as indicated by FAO hence safe for consumption purposes with no expected form of toxicity and health implication to consumers whereas for mercury content, the level was found to be above the permissible limit.
