在鱼苗(种)饵料研究中,日本在海藻酸钠水溶液中加入鱼苗(种)所需营养成分,并使其微粒化,微粒在氯化钙水溶液作用下硬化,生产出一种适于鱼苗(种)摄食的新型颗粒饵料。这种饵料有以下特点:(1)颗粒直径在鱼苗(种)可食范围内;(2)饵料在水中最少漂浮30分钟不沉;(3)在水中不溃散,不膨润;(4)饵料中的营养成分不会溶解到水中;(5)鱼类喜食;(6)饵料散布水中不腐败;(7)幼鱼摄食后能充分消化吸收。具体制法为:方
In the study of fish fry (species), Japan added the nutrients required for fish fry in the sodium alginate solution and micronized it. The particles were hardened by the action of calcium chloride aqueous solution to produce a suitable fry Species) feeding the new particle bait. The bait has the following characteristics: (1) the particle diameter is within the edible area of the fry (species); (2) the bait is floating a minimum of 30 minutes in the water; (3) it does not collapse in the water and does not swell; (5) fish eat food; (6) food is not corrupt in water; (7) juvenile fish can fully digest and absorb after ingestion. Specific system of law is: square
