Intake of fish or omega-3 fatty acids may decrease risk of total and coronary heart disease death, but evidence from low-risk populations is less convincing. The authors assessed intake by using a food frequency questionnaire at baseline in a cohort of Iowa women aged 55-69 years. Among women initially free of heart disease and cancer (4,653 deaths over 442,965 person-years), there was an inver...

In July 2013, using data and plasma collected in the Selenium and Vitamin E Cancer Prevention Trial (SELECT), results were shown consistent with prior results of the controversial 2011 Prostate Cancer Prevention Trial. Both trials exhibited unexpected associations: 1) Fish oil and fish oil’s DHA significantly increase prostate cancer in men; in particular, high grade prostate cancer; 2) Harmful...

The demand for live seafood in Asia has spawned a lucrative trade in live coral reef fish that in 1995 had a global annual retail value of over USD 1 billion (Johannes and Riepen 1995; Cesar et al. 1997). There are concerns that the live reef fish food trade is inflicting an unacceptably heavy impact on coral reefs and reef resources in Southeast Asia and the Indo-Pacific.5 These areas contain ...

23 24 Fish have an absolute dietary requirement for certain polyunsaturated fatty acids (PUFA) 25 termed " essential fatty acids " (EFA) that include members of both the n-6 and n-3 series 26 typified by linoleic acid, 18:2n-6, and α-linolenic acid, 18:3n-3. However, the biologically 27 active forms of EFA are generally the C 20 and C 22 metabolites of 18:2n-6 and 18:3n-3, viz. PUFA through a s...

The potential of Streptomyces as a probiotic feed for the growth of ornamental fish Xiphophorus helleri has been investigated. The Streptomyces strains used as probiotics were isolated from the marine sponges, namely Callyspongia diffusa, Mycale mytilorum, Tedania anhelans and Dysidea fragilis. Seven probiotic feeds were prepared and their effects were compared with those of control diet contai...

Fish discards and by-catch issues are highly topical subjects that are permanently under a social focus. Two main approaches are being considered to address this discard problem: reducing the by-catch and increasing by-catch utilization. Interest in increased by-catch valorization may arise from a greater demand for fish products, such as the development of new markets for previously discarded ...

Scuticociliatosis, which is caused by an opportunistic ciliate protozoan, is responsible for significant economic losses in marine ornamental fish. This study reports the occurrence of Uronema sp., which was found to be parasitizing three species of marine reef fish imported into Brazil and maintained in quarantine: Vanderbilt's Chromis (Chromis vanderbilti), blue-green damselfish (Chromis viri...

Marine environments, key life-support systems for the earth, are under severe threat. Issues associated with managing these common property resources are complex and interrelated. Networks of marine reserves can be valuable for mitigating threats to marine systems, yet the successful design and implementation of such networks has been limited. Efficient ways to conserve marine environments are ...

The genus Tenacibaculum encompasses several species pathogenic for marine fish. Tenacibaculum dicentrarchi and "Tenacibaculum finnmarkense" (Quotation marks denote species that have not been validly named.) were retrieved from skin lesions of farmed fish such as European sea bass or Atlantic salmon. They cause a condition referred to as tenacibaculosis and severe outbreaks and important fish lo...
