Nature-inspired technology has been investigated widely. Anti biofouling properties of fish scale inpired to improve membrane performance. Biofouling affects an oil-water separation membrane. The bacterial, coagulant, and hydrophobic oils attach the surface, demanding periodic cleaning. To overcome problems, surface modification materials are introduced namely superoleophobic surface. promises ...

Scale and otolith patterns are frequently used for age determination, growth estimation, and stock identification of Pacific salmon. However, little information is available about their formation mechanism such as circulus, check in the scale, and growth increment in the otolith. I clarified the formation mechanisms of scale and otolith patterns by rearing experiments using juvenile sockeye and...

“Digital Museum/Library” is an ongoing project sponsored by the National Science Council of Taiwan. The content of this paper is partial result of one of its subprojects called `` Image content-based retrieval on a fish database of Taiwan.'' The objective of this project is to develop an image content-based search engine which can perform identity check of a fish. It is well known that conventi...

Animals living in patchy environments may depend on resource pulses to meet the high energetic demands of breeding. We developed two primary a priori hypotheses to examine relationships between three categories of wading bird prey biomass and covariates hypothesized to affect the concentration of aquatic fauna, a pulsed resource for breeding wading bird populations during the dry season. The fi...

To gauge the collateral impacts of fishing we must know where fishing boats operate and how much they fish. Although small-scale fisheries land approximately the same amount of fish for human consumption as industrial fleets globally, methods of estimating their fishing effort are comparatively poor. We present an accessible, spatial method of calculating the effort of small-scale fisheries bas...

Scale measurements, percentages of annual scale growth, and back-calculated fish lengths were examined for the INPFC method (75 0 anterior reference line) and Traditional method (anterior-posterior reference line) on scales of chum salmon (Oncorhynchus keta) for three ages, two stocks, and two brood years. Mean measurements of annual increments of scale growth were greater for the INPFC method ...
