生物课是职业中学水产养殖专业的一门必修的文化课。从一定意义上说,这又是一门专业基础课,因为生物课作为文化课,除了使学生获得系统的生物学基础知识和基本技能外,还直接为水产养殖专业课的学习打下基础。水产养殖专业开设的课程大多数与生物学密切相关,是以生物学为基础的,有些课程本身就是生物科学的分支和延伸。例如专业基础课中的淡水生物学、海洋生物学、鱼类学、微生物学等是生物学科学的分支,而专业课中的鱼、虾、贝、藻等的养殖以及疾病防治也都以普通生物学为基础。以淡水养鱼为例,要养好鱼,首先要为了解鱼的形态、解剖和生活习性。要懂得作为鱼类饵料的浮游生物和其他可供食
Biology class is a compulsory culture course for aquaculture majors in vocational schools. In a certain sense, this is again a professional basic course, because biology class as a cultural class, in addition to allowing students to gain systematic biological basic knowledge and basic skills, but also directly lay the foundation for the aquaculture professional courses. Most courses offered by aquaculture professionals are closely related to biology and are based on biology. Some courses are themselves branches and extensions of biological sciences. For example, freshwater biology, marine biology, ichthyology, and microbiology in professional basic courses are the branches of biological sciences, while the cultivation of fish, shrimp, shellfish, and algae in specialized courses, and disease prevention and control are all based on common biology. Based on. Take freshwater fish culture as an example. To raise fish well, you must first understand the fish’s morphology, anatomy, and habits. To understand plankton and other edible foods as fish bait
