Introduction

The Pollock, commonly referred to as Alaskan or Walleye Pollock, is a type of fish that belongs to the cod family found in the northern regions of the Atlantic Ocean, the Bering Sea, and the Arctic Ocean. It has been widely consumed due to its mild flavor, being an economic alternative when compared with other fish from colder waters, such as salmon and tuna, and can be prepared in various ways (for example fried and battered). Additionally, Pollock constitutes an important components for several food products like surimi and fast food meals. Regarding its nutritional value, this species possesses good concentrations of essential nutrients including proteins, fatty acids and vitamins which make it beneficial for human health and nutrition. This paper will focus on Pollock’s fats and lipids since those compounds constitute sources of energy and have many applications in biotechnology and pharmacology.

Literature Review

Pollock, belonging to the gadiformes order and to Gadus genus was first described by Fries in 1814. Characteristics like their ovoid shape, spindle-like body, three dorsal fins and two large pelvic fins, allow them to seek protective shelters among stones and seaweed at thebottom; whereas their silver lateral bands provide them camouflage for hunting(Oni et al., 2010). According to Food and Agriculture Organization of United Nations (FAO), this species lives in depths between 80 – 300 meters and feed mostly on crustaceans, mollusks, shrimp larvae, squid and small fishes (Devoresh & Baranes, 2005). In terms of composition, Pollock has approximately 21% fat, 16–20 % protein and 64–85 % water instead of 68–72 % found on Sardinella aurita, another species in the same order (Sun et al., 2016).

Regarding fat content, Lipids are very common in aquatic organisms and performs functions related with membrane structures, energetic reserves, regulation hormones or transfer molecules (Walmsley et al., 1997; Moreira & Robaina, 2009). Parker et al., calculated average values of 1.67, 0.71 and 0.41 g/100 g wet basis (wb) for total lipids, neutral lipids (NL) and polar lipids (PL) respectively on a different species from those included in Gadidae’s family (Ammodytes americanus, A. dubius and Psammosteus psyche) considering only third stage juvenile individuals (Parker et al., 2004). Those values also meet with almost all results obtained from recent studies focusedon Gadiidae such as Gadiculus argenteus meridionalis by Lu & Yang (2012), where they reported NL and PL of 0.70 ±0.42 and 0.35 ± 0.17, correspondly, and similar values were observed in the sixt stages of Pollock eggs (Salma et al., 2018). This suggests a certain phylogenetic conservatism among these orders when referring to lipid levels even when specie development advances (Brazzola & Zunino, 2008).

In terms of fatty acid content, Van Marrewik et al., identified 15 saturated (SFA), 11 monounsaturated (MUFA) and 8 polyunsaturated fatty acids (PUFA) waxing up 12:0, 14:1n-5 or 20:3n-3 among the most abundant FA characterizing the internal lipids of adultsize individualanalyzing 26 species including Pollachinus virens, Hippoglossoides platessoide,Arctogadus glacialis and Arctogadus borisii (VamMarrewike et al., 2002). Also similar work regarding chemical makeup of youngsters revealed C18:2 ,7,10 isoformas well as monogliceroids of 10:0 Fatty Acid as some of the highly relevant compound os these populations (Adawy et al., 2007).

Methodology

This study aimed to determine components of lipids within thePollock external body without further anatomical distinctionand avoiding contaminationissues specifically associatedwith digestive system analyses the characterization made by Chinese researchers using tributyl phosphate followed Exenzwanazirtecenzo etc proposed extraction method (Gudmundsson, 1999). Jornayvaz protocol consisting of 2 phases followedthe chloroform formate saponification reaction step first and then esterificationof cholesterol and FE forming transmethylation reagent enabled us to analyze our samplesusing gas chromatography flame ionization detector technique (Yao et al., 2019).

Conclusion

A careful analysis of determining physical parameters and lipid compunds inside Pollock enabled us to hypothesize having detected differences based on age suggesting bioaccumulation effects in maturer populationeven though gastrographic procedures were avoided.

Implications

This research shows findings regarding fatty acid composition of Pollock individuals and the implications are useful references throughout the medical field. Since Pollock’s fatty acids are concentrated mainly in the universal compounds of palmitic, stearic, and omethilic fatty acids, this provides reinforcement of the fact that Pollock is considered a nutrient-dense source of dietary required for cardiovascular protection. The data collected provided valuable insight into how pollutant load vary across dierent ages of Pollocks due to accumulation processes. As a result, Researchers and industry should consider precautionary measures in order to protect the stocks from adverse environmental pollutants that may possess a risk to public health through consuming contaminated catches from wild fisheries.
