日本最近研制的快餐模拟虾仁风味鱼糜制品不仅成型性好，干燥得率高，而且在食用时用热开水浸泡片刻．其复元性亦好。复元品的外观、弹性、食感以及风味等都酷似虾仁真品。这项生产工艺大致如下：将狭鳕鱼糜经细切机切细后取8公斤，然后放入约95℃的热水中烧煮3分钟，取出待用，此为第一种原料。 相似文献

Shrimps of all sizes are obtained by direct purchasing from independent farms then sorted and sold by size. Shrimp that has not been sold is kept in cold storage, a heavy burden for shrimp processors. In this paper, a mathematical model and a heuristic model based on the dynamic programming are developed to facilitate harvesting decisions for shrimp processors. The objective function of the proposed model is to minimize the cost related to by-size inventory. The effectiveness of the heuristic model is evaluated under a combination of scenarios with various parameters. The results demonstrate that the heuristic model is quite effective and practical in solving the problem. 相似文献

对虾作为水产业中的支柱品种,一直深受广大消费者的喜爱,也是水产品中出口量较多的品种之一.针对目前对虾养殖过程中施用禁用药物、可用药物用量过多、成虾体内有害物质残留超标等问题,海南省水产研究所于2003年进行了"南美白对虾无公害养殖技术研究"项目,并在项目实施过程中采用了SPF南美白对虾苗种,养殖过程中不投放抗生素等禁用渔药,利用有益微生物改善与优化水质以降低水体中有害物质在虾体内的残留,再结合温性中草药的合理利用来防治虾病,结果表明,养殖对虾各项指标均符合我国无公害对虾标准,达到国内出口与国外进口食品标准,而且产量高,经济效益好. 相似文献

近年来由于日本对虾的价格远高于同规格的中国对虾,故在北方地区兴起了养殖日本对虾的热潮,从而引发了对日本对虾苗种的大量需求。使许多过去进行中国对虾苗种生产的育苗单位改为进行日本对虾苗种的培育。本文就中国对虾与日本对虾在苗种繁育的方法方面进行了一些比较。（一）亲虾培育1亲虾来源：中国对虾的亲虾来源主要有经养殖虾越冬培育而成鹏称越冬虾以自然海区捕捞的亲虾;而日本对虾育苗所用亲虾全部来源于自然海区捕捞。2暂养水温：中国对虾亲虾暂养温度一般首先控制在14℃以下,这有利于亲虾的恢复．然后再逐步升温至18℃,促进性… 相似文献

Multi-stage penaeid shrimp grow-out systems have considerable advantage over conventional single-stage grow-out systems. A multi-stage shrimp grow-out system has more than one production stage wherein the shrimp stocking density changes as the shrimp grow in size and are moved from one production stage to the next. The shrimp stocking density (shrimp/m2) is at its highest when the shrimp post larvae enter the first production stage and is reduced each time the shrimp are transferred to subsequent stages. The use of multi-stage instead of single-stage production systems has been considered by numerous authors. This paper presents a methodology by which to select the optimum number of stages for a production system and, using available data, demonstrates that optimum efficiency can be achieved, in most cases, by using a two-stage production system consisting of a prolonged nursery stage followed by a grow-out stage. 相似文献

Socio-economic impacts of shrimp culture 总被引：8，自引：0，他引：8

Farmed shrimp contributed 27% of total world shrimp production in 1995 with a volume of 712 000 tonnes. Undoubtedly, the shrimp culture industry earns valuable foreign exchange for developing countries and generates jobs across the industry from fry gatherers to growers and processors. However, grave socio-economic consequences – including conversion, expropriation and privatization of mangroves and other lands; salinization of water and soil; decline in food security; marginalization of coastal communities, unemployment and urban migration; and social conflicts – have followed in the wake of, shrimp farm development in the Philippines and other tropical countries. The paper focuses on mangrove ecosystems: the valuation and cost-benefit analysis of their goods and services, and the mangrove-offshore fisheries connection. Research gaps in these areas and the need to internalize the ecological and socio-economic costs (‘externalities’) of shrimp farming are highlighted. Other recommendations include mangrove conservation and rehabilitation, enforcement of existing legislation, and introduction of environment-friendly aquaculture within the broader framework of community-based, integrated coastal area management, e.g. the traditional, extensive polyculture ponds in Indonesia. 相似文献
