| The success of hatchery production of bivalves remains highly unpredictable and mortalities are often attributed to deficiencies in certain nutritionally important components. Several studies have implicated the importance of lipids, in particular triglycerides, in the early life stages as a source of energy and essential fatty acids. Experimental diets used so far in bivalve nutrition studies are either heavily polluting the water or too complex to prepare on a regular basis in a hatchery. Self emulsifying concentrates of marine oils are off-the-shell lipid supplements that may be acceptable for bivalves. A series of studies were performed with different species and life stages to evaluate the potential use of these lipid emulsions as a supplement for... |

| <i>Penaeus monodon</i> postlarvae (PL-5) were reared for 10 days on <i>Artemia nauplii</i> enriched with various levels (2.65, 5.30, 12.60, 22.35 and 31.20 mg/g DW) of (n-3) highly unsaturated fatty acids (HUFA). On day 5 and 10, their resistance to osmotic shocks (transfer from 30 ppt to 0, 5, and 10 ppt diluted seawater) was analyzed. After 5 days, postlarvae fed <i>Artemia</i> containing 12.6 mg/g (n-3)HUFA or more had a significantly higher resistance (p<0.05) than controls. Five days later, no significant difference could be detected among the treatments. A positive correlation was found between the stress resistance of PL-10 and the survival recorded five days later in each tank (p<0.02). It is concluded that... |

| Juvenile <i>Tapes philippinarum</i> (Adams and Reeve) were reared for three weeks on different rations of <i>Chaetoceros neogracile</i> which were either centrifuged and stored or fed together with the culture medium. Algal rations were adjusted daily in order to feed constant weight-specific daily rations. Growth of <i>T. philippinarum</i> fed the concentrate of <i>C. neogracile</i> was maximal at a daily ration of 1% (algal dry weight per clam live weight). <i>T. philippinarum</i> fed single or mixed diets of <i>C. neogracile</i> and <i>Isochrysis</i> sp. (clone T-Iso) directly from the algal cultures, maximized growth at a ration of 1,3% day <sup>-1</sup>.... |

| <i>Penaeus monodon</i> postlarvae (PL-5 to PL-15) were fed 5 different diets consisting of enriched <i>Artemia nauplii</i> with a specific n-3 HUFA content. Although the postlarvae grew well on an <i>Artemia</i> diet with low HUFA-content, the ability of PL-10 to endure osmotic stress remained low. Feeding <i>Artemia</i> enriched with medium levels of n-3 HUFA (sum n-3 HUFA =12,55mg/g DW) for 5 days considerably enhanced the resistance of PL-10 to osmotic stress and their survival recorded 5 days later. However, very high dietary levels of n-3 HUFA (31,2 mg/g DW) did not have any growth promoting effect, thus suggesting that an excessive supply of n-3 may not be beneficial to the shrimp. Our data demonstrate... |

| Marine aquaculture, particularly the salmon farming industry, has expanded very fast in Chile. Currently the country ranks second among the world leading salmon producers. However, there is a growing concern for the diversification of aquaculture activities. Examples are the cultures of flatfishes, either the introduced turbot (<i>Scophthalmus maximus</i>) or the native flounder species <i>Paralichthys microps</i> and <i>P. adspersus</i>, along with the native scallop, <i>Argopecten purpuratus</i>. Although both turbot and scallop farming have had a successful transition from pilot to industrial scale, dependable availability of larvae/seed at cost-effective prices is, unlike the situation in the salmon... |
