池塘养鱼具有举足轻重的地位,因此对池塘渔业各项生产计划指标的完成情况和对生产活动中人力、物力的实际消耗与生产成果进行全面考核,从中找出规律,为池塘养鱼的技术改造和渔业生产建设提供科学依据,意义重大。本文试根据益阳县的实际,将重点调查的18户不同类型的池塘养鱼资料,作以下浅析。一、不同美型池塘养鱼技术经济指标分析池塘依据其地理条件及其成因的不同,可分为基地型、平塘型、山塘型三大类。现将三种类型的池塘1986年的渔业生产情况列表如下,进行各种技术经济指标的分析研究。 1.亩产量。从表中可以计算出基地型、平塘型、山塘型池塘每亩毛产量分别为481、462、334公斤,亩净产分别为440、346、300公斤,以基地型最高,平
Pond fish culture plays a decisive role. Therefore, it is necessary to conduct a comprehensive assessment of the completion of various production plans of the pond fishery, as well as the actual consumption of manpower and material resources and production results in the production activities, and find out the law for the technological transformation of pond fish culture And fishery production and construction to provide a scientific basis, of great significance. Based on the actual situation in Yiyang County, this paper will focus on the survey of 18 different types of pond fish farming data for the following analysis. First, the United States and the United States on different ponds technical and economic indicators analysis Pond according to its geographical conditions and the causes of different, can be divided into base type, Pingtang type, Shantang type three categories. The fishery production of the three types of ponds in 1986 is listed as follows, and various technical and economic indicators are analyzed and studied. 1. Mu production. From the table can be calculated base type, Pingtang type, shanty ponds per acre gross output were 481,462,334 kg, respectively, net mu yield of 440,346,300 kg, with the highest base type, flat
