Reputational damage and the Fukushima disaster: an analysis of seafood in Japan

As the levels of radioactivity in seafood have fallen back into the safe range, Fukushima fisheries are considering reopening. However, even if seafood from the Fukushima area were sufficiently safe to distribute to seafood markets, its value may be undermined because of the damage done to its reputation by the Fukushima disaster. We quantified consumers’ preferences for seafood ...

Estimation of the abundance of the sei whale Balaenoptera borealis in the central and eastern North Pacific in summer using sighting data from 2010 to 2012

The abundance of the sei whale Balaenoptera borealis in the central and eastern North Pacific (north of 40°N, south of the Alaskan coast including both the US and Canadian Exclusive Economic Zones between 170°E and 135°W), from July to August, was estimated by the line transect method using sighting data obtained during the 2010–2012 International Whaling Commission-Pacific Ocean ...

Age estimation of Antarctic minke whales Balaenoptera bonaerensis based on aspartic acid racemization technique

Counting of the growth layers in the earplugs is the most accepted technique for determining chronological age of Antarctic minke whales; however, unreadable growth layers form in some individuals, especially in young animals. In this study, aspartic acid racemization (AAR) technique was developed for estimating ages in this species with the aim of complementing the age estimated ...

Distribution of small plastic fragments floating in the western Pacific Ocean from 2000 to 2001

Sampling was conducted at 31 sites in the western Pacific Ocean from 2000 to 2001 with the aim of collecting plastic fragments with a neuston net (mesh size 1.00 mm × 1.64 mm). Small plastic fragments including microplastics (small fragments in the size range of 1.1–41.8 mm) were collected at multiple survey sites. Waters with high densities of small fragments were observed between ...

Recreational fisheries in the UK: natural capital, ecosystem services, threats, and management

The island nature of the UK has led to its long history of commercial marine fisheries, with associated recreational fisheries along and near to its extensive shoreline. In addition, an abundance of fresh waters provides extensive recreational fisheries, but few commercial fisheries, on rivers and lakes where catch-and-release is prevalent. Here, an overview is presented of these ...

Vitellogenesis and choriogenesis in fishes

In studies of sex discrimination in fish in the early 1900s, a specific antigen in the blood of gravid females was identified using immunological methods. At present, this specific antigen is known as vitellogenin, the major precursor of egg yolk protein that is synthesized in the female liver and is secreted into the blood to be incorporated into the egg. Recently, protein and ...

Narrowed temperature adaptability in non-natal osmotic environments of two euryhaline wanderers, dace and black porgy: implications for seasonal habitat changes

Many euryhaline wanderer species exhibit seasonal habitat changes, and temperature is suggested to play a key role in this phenomenon. To examine this possibility, we tested the hypothesis that adaptable temperature ranges of euryhaline wanderers are narrower in a non-natal osmotic environment than in their natal osmotic environment using dace Tribolodon hakonensis, a freshwater ...

Comparison of olfactometrically detected compounds and aroma properties of four different edible parts of Chinese mitten crab

Chinese mitten crab Eriocheir sinensis from the Songjiang district in Shanghai is popular among Chinese consumers due to its unique pleasant aroma. In this study, volatile compounds in four edible parts of steamed male E. sinensis were extracted by the monolithic material sorptive extraction method and analyzed by gas chromatography-mass spectrometry/olfactometry, the E-Nose ...

Characterization of important odorants in four steamed Coilia ectenes from China by gas chromatography–mass spectrometry–olfactometry

Odorants were extracted from four Coilia ectenes (Yangtze River-Coilia, East China sea-Coilia, Chao Lake-Coilia and Yellow River-Coilia) by MonoTrap™ and analyzed by the headspace-monolithic material sorptive extraction technique combined with gas chromatography–mass spectrometry–olfactometry (GC–MS–O). A total of 63 volatile compounds were identified. The results of GC–MS–O ...

Prediction of on-site depuration of paralytic shellfish poisoning toxins accumulated in the scallop Patinopecten yessoensis of Ofunato Bay, Japan

In this paper, we present a decay equation for paralytic shellfish poisoning (PSP) toxins using long-term field data spanning more than 10 years in order to predict the detoxification period for the scallop Patinopecten yessoensis in Ofunato Bay, Japan. From the data, we obtained the date of maximum toxicity in the digestive gland (DG) of the scallop and then the date of ...

Possible involvement of Tachylectin-2-like lectin from Acropora tenuis in the process of Symbiodinium acquisition

Most reef-building corals in tropical and subtropical areas symbiose with microalgae from the genus Symbiodinium (dinoflagellate) and depend on the photosynthate produced by the microalgae. The majority of corals acquire Symbiodinium from the surrounding environment through horizontal transfer, but the molecular mechanisms involved in the acquisition of Symbiodinium remain unknown. ...

Investigation of the hazardous substance causing crayfish-induced rhabdomyolysis via a mouse model, a hemolysis assay, and a cytotoxicity assay

The hazardous substance from Procambarus clarkii could cause rhabdomyolysis. Mice were administered mashed muscles and gills, intestines, and glands (GIG) obtained from cooked crayfish by gavage . Three of seventy-two mice administered with GIG (with an incidence rate of 4.17 %) appeared to have rhabdomyolysis symptoms with the serum creatine kinase (CK) content increased by more ...

DNA vaccine-mediated innate immune response triggered by PRRs in teleosts

Aquacultured fish are threatened by many pathogens, often with serious consequences. Vaccination is one of the most effective tools for enhancing host immunity and protecting fish from infections. Vaccination with DNA vaccine is based on the administration of the gene encoding a vaccine antigen. Several effective DNA vaccines that encode viral or bacterial antigenic proteins have ...

Progression in artificial seedling production of Japanese eel Anguilla japonica

Eel aquaculture, though thriving nowadays, is totally dependent on the successful capture of wild eel fry and glass eels for its seedlings. The declination of eel resources in recent years has resulted in an urgent need for technology development in artificial seedlings production on an aquaculture basis, in order to protect natural resources and to stabilize the eel supply in the ...

Stock assessment of Japanese eels using Japanese abundance indices

The paper compiles a catch history of Japanese eels Anguilla japonica in East Asia and some Japanese relative abundance series. Maximum likelihood estimates of stock abundance of eels have been obtained using the abundance series and various biological parameters, such as growth, maturity and natural mortality. Age- and sex-structured models have been used to express the dynamics ...

Evaluation of the microbiological safety and quality of Vietnamese Pangasius hypophthalmus during processing by a microbial assessment scheme in combination with a self-assessment questionnaire

Pangasius hypophthalmus (referred to as Pangasius or tra fish in Vietnam) has become highly appreciated by consumers in the European Union, USA, Japan, etc. and is of worldwide economic importance. Therefore, the microbial quality and safety of Pangasius fish processed for export was assessed by means of a microbial assessment scheme throughout the entire production process. A ...

Progress on larval and juvenile nutrition to improve the quality and health of seawater fish: a review

In seedling production of seawater fish, providing appropriate nutrition is a necessity for successful production of quality larvae and juveniles. Mass-produced live prey organisms, such as the rotifer Brachionus plicatilis species complex and brine shrimp Artemia spp., alone do not provide sufficient nutrition to the larvae and juveniles of seawater animals. This inadequacy has ...

Japanese chum salmon stock enhancement: current perspective and future challenges

This study reviews the present status of the Japanese chum salmon Oncorhynchus keta stock enhancement program and considers the ecological sustainability of wild populations while providing fishery production, exemplified by the hatchery-based Kitami region set net fishery. The return rate and the number of returns have been historically high in the Sea of Okhotsk, but have ...
