象山港湾土质主要为轻粘土、中粘土,港内风浪小、泥沙少、水清。港口内多往复流,落潮流速大于涨潮,故而沉积少而主槽水深稳定。诸多先天优质的生态条件,有利于海洋生物栖息、繁殖和生长。优越的港湾生态环境带来了丰富的海产资源。宁波的海洋捕捞最早的记载见于西晋陆运《答车茂安书》中,“断遏海浦,隔截曲隈,随潮进退,采蚌捕鱼。鲔赤尾,锯齿比目,不可纪名。”比较具体地描述了宁波浅海滩涂 Xiangshan Harbor soil is mainly light clay, clay, Hong Kong storm small, less sediment, clear water. More reciprocating flow within the port, ebb flow rate is greater than the tide, so less sediment and the main channel of water depth and stability. Many innate high quality ecological conditions are conducive to habitat, reproduction and growth of marine life. Superior harbor ecological environment has brought rich seafood resources. The earliest record of marine fishing in Ningbo found in the West Jin land “answer Ma’an book,” “cut off Haipu, cut off from the song, tide advance and retreat, mining mussels. ”A more specific description of Ningbo shallow beach coating
