Crustacean aquaculture is a multibillion-dollar industry worldwide that continues to show significant growth. Shrimp farming has been intensified for decades, and super-intensive closed culture systems have now been developed to improve productivity and reduce environmental burdens. Here, we used bio-economic approaches to investigate the mechanism...

In this study, we developed a novel bioreactor system to deliver and accumulate foreign proteins in eggs using medaka fish Oryzias latipes with the aid of a partial sequence of vitellogenin (Vtg). In teleost fish, Vtg, the hepatically generated precursor of egg yolk proteins, is secreted into the bloodstream and then taken up into eggs. We predicte...

Treated sewage discharge has been reported to affect multiple levels of biological organization in fish and fish community structure. In this study, a split-plot ANOVA design was used to test species diversity of fish assemblages in Taiwan. The samples were collected seasonally, from 2005 to 2016, at three different stations near the ocean outfall ...

Molting is a critical developmental process for crustaceans, during which the claw muscles undergo periodic atrophy and restoration. The regulatory mechanism of this special muscle reshuffle around ecdysis was not clear. To investigate the molecular mechanism underlying the muscle changes in crustaceans, we used Illumina/Solexa deep sequencing tech...

We detected an earthy/musty off-flavor in the flesh of red sea bream Pagrus major cultured under low saline water conditions using two types of recirculating aquaculture systems (RAS). The compound causing the off-flavor was identified, and we investigated how the ultraviolet (UV) equipment of the RAS affected the concentrations of off-flavor compo...

Crustacean hemocytes, which have usually been classified morphologically based on methods using Giemsa or May-Giemsa stains, have recently been categorized using monoclonal antibodies or marker genes. However, these latter techniques are not yet widely used, and different classification methods are used for hemocytes among laboratories. Therefore, ...

Marine Streptomyces sp. isolate S073 was shown to have strong antagonistic activity towards the pathogenic Vibrio parahaemolyticus using the agar diffusion method. The antagonistic substance(s) secreted into the supernatant was thermostable and non-proteinaceous in nature. S073 was found to produce carboxylate-type siderophores during most of its l...

We examine geographical differences in percentages of age-1 Pacific saury Cololabis saira with previous spawning experience collected from 143°E to 165°W during June and July of 2013 and 2014. Previous spawning experience of fish was determined using a new histological method involving Victoria blue (VB)-positive ovarian arterioles. We also compare...

Fisheries subsidies have attracted considerable attention worldwide since the 1990s. The World Trade Organization (WTO), among others, started to strengthen its disciplines in fisheries subsidies in 2001. The academic study of fisheries subsidies can play a key role in contributing to policy-making processes such as WTO negotiations by providing mo...

Surrogate broodstock technology facilitates the production of donor-derived gametes in surrogates, and comprises transplanting germ cells of a donor into recipients of a different strain or different species. The following applications of this technology are expected in the field of aquaculture: (1) the efficient and reliable production of offsprin...
