Protein Efficiency Ratio (PER) is the most widely used method for determining protein quality. The studies involved a few category of products as raw materials namely poultry products, beef burger products, fish and fish products, soy products and palm kernel cake in animal diet preparation were compiled to compare the data. Data from the proximate analysis showed that protein content in soy pr...

One of the principal purposes of studying the nervous system is t o correlate the observed gross and microscopic structure with the dynamic activity of the animal, that is, its behavior patterns. Coordinated swimming movements, feeding, and schooling can be observed in larval fish as soon as the neural pathways, sensory and motor, are sufficiently developed. On the other hand, mating and spawni...

Over the past decade, the distribution of harbour porpoises Phocoena phocoena has undergone a southward shift in the North Sea, which has led to an increase in the number of stranded porpoises in its southern part. Since the changes in distribution and relative abundance of porpoises may be linked to the changes in prey availability, the aim of the present work was to investigate whether any ch...

Fresh sardine (employed as discard model species) was pressed with a hydraulic press in order to obtain a partially dewatered cake (whose volume represents between 55% and 60% of the initial volume of raw material) and a 3-phase press liquor comprising an aqueous fraction, an oil fraction and a variable amount of suspended solids. Pressing conditions, such as final pressure to which the sardine...

Combining different preservative treatments for improving quality and safety of fishery products increasingly receives global research attention. Consistent with this pursuit, the current research was undertaken to determine the effects of different ozonized slurry-ice treatments and superchilling (-1°C) storage on microbial spoilage of European anchovy (Eugraulis encrasicolus) and sardine (Sar...

Lombok Strait has abundance of Sardine, Sardinella lemuru, which contains such high amount of omega-3 fatty acid (omega-3). However, the genetic relationship of S. lemuru with other commercial fish rich in omega-3 has not been widely studied yet. Studies on genetic proximity of S. lemuru with the other marine fish using 12S rRNA gene is very important in order to obtain genetic information of t...

Coastal marine ecosystems worldwide have undergone such profound transformations from over-fishing that trophic interactions observed today might be artifacts of these changes. We determined whether the trophic level of an endangered seabird, the Marbled Murrelet (Brachyramphus marmoratus), has declined over the past 100 years after the collapse of Pacific sardine (Sardinops sadax) fisheries in...

Using numerical simulations of the mixed common sardine and anchovy fishery of central-southern Chile, this article studies the effects of the distribution of administrative costs between the government and the fishing industry in an individual transferable quota system. Consistent with recent theoretical results, the analysis indicates that the presence and distribution of the administrative c...

In this study we describe the diversity of Mesembrinelinae in a biological reserve in the city of Nova Iguaçu, State of Rio de Janeiro. Traps containing sardines were distributed seasonally, at four sites: Site A (22° 58.788' S, 43° 43.459' W), in a forest edge, and sites B (22° 58.523' S, 43° 44.540' W), C (22° 58.350' S, 43° 44.678' W), and D (22° 34.865' S, 43° 27.063' W), located 1,000 m, 5...
