In this plan 84.8% Sparus macrocephalus embryos are able to keep forms comparative normal, however, revival has not been found so far.

三者配合虽然没有得到复活胚胎，但能得到84.8%胚体、卵膜、卵黄囊和油球等形态都基本正常的胚胎。

In the acute toxicity experiments, the 96h-LC50 were 1.0×105 cells·mL-1 for the intact algal solution and 8.0×104 cells·mL-1 for the lysate. In a 7 day subacute experiment on the larvae, higher concentrations of algal solution inhibited S. macrocephalus larvae. The toxicity of the algal solution was higher than that of the lysate at the same concentration.

在仔鱼96h的急性毒性实验中，微小亚历山大藻对仔鱼的96h理论半致死浓度分别为1.0×105 cell·mL-1、8.0×104 cell·mL-1，而在7d的亚急性实验中，高浓度藻细胞液对仔鱼的生长发育有一定的抑制作用，且相同浓度下，藻细胞液产生的毒性较藻细胞破碎液大。

The bio-toxicity of the dinoflagellate Alexandrium minutum on black seabream was studied by observing the acute toxicity and subacute toxicity of A. minutum on the S. macrocephalus embryo and larvae. The presence of A.

通过微小亚历山大藻对黑鲷胚胎及仔鱼的急性和亚急性毒性的实验，研究了微小亚历山大藻其藻细胞液和细胞破碎液对黑鲷幼体的生物毒性效应。

In the acute toxicity experiments, the algal solution and breakup solution of the concentration of 96h-LC50 were 1.0×105cells/mL and 8.0×104cells/mL, respectively. In the subacute 7 days experiment of the larvae, higher of the algal solution has the inhibition effect on sparus macrocephalus larvae. The toxicity of algal solution was higher than that of breakup solution at the same concentration.

The male's swimbladders increased faster than weight the than females. Morphology of the sciaenids can be grouped to two types. Type I including red drum: the ratio of sonic muscle and body weights is smaller, and the sonic muscles are tightly connected to the swimbladder. Type II including Pennahia argentata, Johnius tingi, Atrobucca nibe, Larimichthys polyactis, and Pennahia macrocephalus: the ratio of sonic muscle and body weights is larger, and the sonic muscles are loosely connected to the swimbladder by membrane tissue.
