基于营养盐供需平衡法的长岛海域海带养殖容量评估
Assessment of Laminaria japonica Aquaculture Capacity in Changdao Area Based on Nutrient Budget Method
摘要
Abstract
To assess the Laminaria japonica capacity in the northern area of Changdao(Daqin Island,the assessed area is 1 066.667 2 hm2),the limiting nutrient factor of the area was determined according to the Justić standard and the Redfield ratio method,the capacity of L.japonica culture was evaluated based on nutrient budget method.Results showed that the limiting nutrient in the northern area of Changdao was silicon.The total amount of silicon input from seawater exchange,overlying water-sediment exchange,animal excretion and atmospheric wet sedimen-tation in the culture area was 67.731 9 t,the total amount of silicon required for the natural population growth of phytoplankton and macroalgae was 61.894 9 t.Therefore,the total amount of silicon available for L.japonica growth was 5.837 0 t.It was estimated that the culture capacity of L.japonica in the northern waters of Changdao(Daqin Island)was 23 631 t(based on dry L.japonica),and the culture capacity was 22.154 0 t per hectare.In conclusion,the yield of L.japonica in the northern area of Changdao(2020)has reached the theoretical value of the aquaculture capacity.关键词
