This study evaluates the growth, proximate, and fatty acid composition of black mussel, Mytilus galloprovincialis fed four marine microalgae (Pavlova lutheri, Nannochloropsis oculata, Diacronema vlkianum and Rhinomonas reticulata) diets for 21 days. Black mussel is a common bivalve species that has been recognized as important for marine aquaculture with increasing production in the last two decades. The mussel group fed N. oculata showed a significantly lower survival rate than the other groups (p < 0.05). Shell height, length, and width of mussels were measured. The height and length of the mussel group fed N. oculata were statistically higher than other experimental groups (p < 0.05). Shell width did not show any significant differences among groups (p > 0.05). The microalgae N. oculata showed the highest protein content whereas P. lutheri had the highest crude lipid content among dietary treatments. The group fed P. lutheri showed significantly higher protein, lipid, and ash contents among experimental groups (p < 0.05). The D. vlkianum diet enhanced the highest docosahexaenoic acid level in black mussels. Black mussel fed P. lutheri showed the highest eicosapentaenoic acid and polyunsaturated fatty acid levels. Arachidonic acid was found to be similar among experimental groups. In our study, P. lutheri and D. vlkianum had outstanding results on survival, growth, and essential fatty acid accumulation in mussel culture.

微藻饲料对黑贻贝（Mytilus galloprovincialis）生长、近似值和脂肪酸组成的影响

本研究评估了黑贻贝（ Mytilus galloprovincialis）在 21 天的时间内喂食四种海洋微藻（Pavlova lutheri、Nannothropsis oculata、Diacronema vlkianum和Rhinomonas reticulata ）的生长情况、近似值和脂肪酸组成。黑贻贝是一种常见的双壳类物种，在过去二十年中产量不断增加，已被认为对海水养殖很重要。喂食N. oculata的贻贝组的存活率显着低于其他组 ( p  < 0.05)。测量贻贝的壳高、长度和宽度。喂食N. oculata的贻贝组的高度和长度在统计学上高于其他实验组（p  < 0.05）。各组之间的壳宽度没有显示出任何显着差异（p  > 0.05）。在膳食处理中，微藻N. oculata 的蛋白质含量最高，而P. lutheri 的粗脂含量最高。与实验组相比，饲喂P. lutheri的组的蛋白质、脂质和灰分含量显着较高（p  < 0.05）。 D. vlkianum饮食提高了黑贻贝的最高二十二碳六烯酸水平。饲喂P. lutheri 的黑贻贝显示出最高的二十碳五烯酸和多不饱和脂肪酸水平。发现实验组之间的花生四烯酸相似。在我们的研究中，P. lutheri和D. vlkianum在贻贝养殖中的存活、生长和必需脂肪酸积累方面具有出色的结果。
