Various compounds have been used for microencapsulating of fish oilso far, but in thiswork for the first time, inulin and casein which are both known for their functional properties, were used as the coating materialof fish oil.This study aimed to investigate the properties of nano-emulsions (droplet size measurements and pH) based on changes in the concentration and type of wall and their effe...

Collective motion phenomena in large groups of social organisms have long fascinated the observer, especially in cases, such as bird flocks or fish schools, where large-scale highly coordinated actions emerge in the absence of obvious leaders. However, the mechanisms involved in this self-organized behavior are still poorly understood, because the individual-level interactions underlying them r...

Fish scales are among the structural materials in nature that inspiring design and development of “next-generation” engineering materials. possess a mineralization gradient divides their thickness into three unique regions, each containing characteristic structures properties. Here, experiments complementary numerical modeling performed to understand importance different geometrical mechanical ...

Beaver have been referred to as ecosystem engineers because of the large impacts their dam building activities have on the landscape; however, the benefits they may provide to fluvial fish species has been debated. We conducted a watershed-scale experiment to test how increasing beaver dam and colony persistence in a highly degraded incised stream affects the freshwater production of steelhead ...

In recent years, a debate about the degree to which prehistoric fishing practices may, or may not, have adversely impacted local fish communities has re-emerged in the Caribbean archaeological and fisheries literature. Through carbon and nitrogen stable isotope analyses of radiocarbon dated human skeletal remains from southeastern Puerto Rico, the present work identifies a significant (one to t...

Plots of local versus regional richness have been used to test whether assemblages are ‘saturated’ with species. However, the validity of these tests is limited by scale-dependence and arbitrarily defined sampling units, statistical autocorrelation between local and regional richness data, and the confounding effects of propagule pressure. In this study, local versus regional richness plots wer...

Novel type I collagen hybrid fibrils were fabricated by neutralizing a mixture of type I fish scale collagen solution and type I porcine collagen solution with a phosphate buffer saline at 28 °C. Their structure was discussed in terms of the volume ratio of fish/porcine collagen solution. Scanning electron and atomic force micrographs showed that the diameter of collagen fibrils derived from th...
