Fish and Omega-3: Questions and Answers for Health Professionals
Fish and omega-3: Questions and answers for health professionals The Heart Foundation recommends all Australians should aim to include 2–3 serves of fish (including oily fish) per week as part of a heart-healthy diet. This provides around 250–500 milligrams (mg) of marine-sourced omega-3s (EPA, DHA) per day. The Heart Foundation also recommends that all Australians should aim for 1 gram of plant-sourced omega-3 (ALA) each day. The Heart Foundation based these recommendations on a scientific review of evidence. For more information, you can access the full text article in the journal Heart, Lung and Circulation, available at www.heartlungcirc.org/article/S1443-9506(15)00167-5/abstract Marine-sourced and plant-sourced omega-3s should be included as part of a heart-healthy diet that includes vegetables and legumes, fruit, wholegrain cereals, lean meats and their alternatives, fish, nuts and seeds, reduced fat milk, cheese and yoghurt, healthier fats and oils, and limits salt. Key messages Fish The Heart Foundation recommends all Australians should aim to include 2–3 serves of fish (including oily fish) per week as part of a heart-healthy diet. This provides around 250–500 mg of marine-sourced omega-3s (EPA, DHA) per day. Because the body cannot produce omega-3s they need to be sourced through diet. The scientific evidence supports fish as the best dietary source of omega-3s and found higher fish intake was consistently associated with lower rates of heart disease (heart failure and sudden cardiac death) and stroke. Fish with the highest levels of omega-3 include salmon, blue-eye trevalla, blue mackerel, herring, canned sardines, canned salmon and some varieties of canned tuna. -

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences. -

Relationship Between Sagittal Otolith Size and Fish Size in Engraulis Encrasicolus and Sardina Pilchardus

Aquatic Sciences and Engineering, 33(3): 72-76. ABSTRACT The objective of this study was to determine the regressions between otolith size (length and height), oto- lith weight vs. fish length, and weight of European anchovyEngraulis encrasicolus (Linnaeus, 1758) (n=360) and European pilchard Sardina pilchardus (Walbaum, 1792) (n=360), living off Güllük Bay, Turkey. Fish were caught using a purse seine between January and March 2014 in the southern Aegean Sea. No differences were found between the size and weight of the left and right otoliths. Equations were used to reconstruct the original dimensions of prey from the size of hard structures found in food samples of piscivorous preda- tors living in or in the vicinity of the aquatic habitat. A linear regression model was used to determine the relationship between fish length and otolith size, whereas an exponential regression model was used to describe the relationships between lengths and weights of otoliths and fish for both species. All regressions yielded high coefficients of determination (r2) of 0.78–0.93 for E. encrasicolus and 0.80–0.95 for S. pilchardus. We conclude that otolith length and otolith weight are good indicators of the length and weight of the two species. -

At the same time, declines in sardine and anchovy biomass have been observed in the NW Mediterra nean Sea, necessitating an assessment of whether the expansion of round sardinella may affect sardine and anchovy populations. Here, we combined stomach content and isotopic analyses to describe the trophic habits of round sardinella in the NW Mediterranean Sea and its trophic relationships with 2 sympatric small pelagic fish, European anchovy Engraulis encrasicolus and European pilchard Sardina pilchardus . Results revealed changes in the diet of round sardinella during the year. In summer, the most important prey were copepods ( Acartia spp.) and cladocerans ( Penilia avirostris ). During winter, the diet was composed mainly of copepods and tunicates (mainly appen- dicularians), but microplankton was also numerically important in adult diets. In contrast to previ- ous studies, during spring, round sardinella principally fed on salps (Thaliacea). To our knowledge, this is the first time that salps have been identified as an important prey for round sardinella. -

23. Fish Stocks and Fish Landings
23. Fish stocks and fish landings Key message Fishing dynamics has been influenced by two main factors: fish stock and fishing quota. Most of the commercial fish stock is in safe biological limits. Cod is permanently overfished. Tunas represent about 15 to 20% of this value. Annual landings by major group of species have varied little for several years. Prices for most of fish species follow the general trend. Photo: Evalds Urtans Why monitor fish stock and fish landings? Fish is a natural resource – essential aspect not only for aquatic ecosystems, but also an important resource for fishing industry. Fishing has direct impact on aquatic ecosystems by removal of organisms from the environment, which is the sum of fish stock landed and discarded (returned). Fisheries can be 'directed' at single species but, more commonly, a variety of species are caught. In addition to target species, a particular fishery may often take a by-catch of other species, some of which may be landed. Costal fisheries are especially affected by decreasing fish stock as they are not flexible to adapt and change. However, in many costal areas fishing is still important source of income. By measuring changes in fish stock it is possible to identify human pressure on aquatic environment and plan fishing intensity. The impact of fishing must be assessed against the state of the stock and its ability to recover. Stocks are ‘overfished’ or outside safe biological limits (SBL) when the fishing pressure (mortality), exceeds recruitment and growth. The number of stocks within SBL is expressed as a proportion of the total number of commercial stocks for which status has been assessed. -
