Description
技术领域：Technical field:
本发明属于海洋农业中贝类养殖技术领域，具体涉及一种提高香港牡蛎经济效益的单体连接养殖方法。The invention belongs to the technical field of shellfish culture in marine agriculture, and in particular relates to a single-unit connection culture method for improving the economic benefits of Hong Kong oysters.
背景技术：Background technique:
香港牡蛎Crassostreahongkongensis是我国华南沿海养殖的主要经济种，喜欢生活在近河口或附近有淡水注入的地方，主要分布在广东、广西等地，年产量在130多万吨，产值在80-100亿元(中国渔业年鉴，2013)。香港牡蛎与其它牡蛎种类相比较，其价值主要体现在体大肉肥、味道鲜美，另外其市场价值远高于其它种类牡蛎，深受广东、广西、港澳、东南亚一些国家消费者青睐(张跃环等，2014)。Hong Kong oyster Crassostreahongkongensis is the main economic species of coastal culture in South my country. It likes to live near estuaries or places with fresh water injection. It is mainly distributed in Guangdong, Guangxi and other places. The annual output is more than 1.3 million tons, and the output value is 8-10 billion yuan. (China Fisheries Yearbook, 2013). Compared with other types of oysters, the value of Hong Kong oysters is mainly reflected in their large body, fat meat, and delicious taste. In addition, their market value is much higher than that of other types of oysters, and they are favored by consumers in Guangdong, Guangxi, Hong Kong, Macao, and Southeast Asian countries (Zhang Yuehuan, etc., 2014).
香港牡蛎在我国有近千年的养殖历史，其主要养殖方法分为滩涂插植、沉排垂下式养殖、筏式垂下式养殖、棚架式养殖等类型。其中，浮筏和沉排是两种最为重要的养殖方式，以往蚝农们均采用野生苗种进行养成。其中，存在着一些问题，一是如果苗种密度过大，其生长速度就比较缓慢，繁殖季节及其冬季死亡率高，养殖周期长；二是如果苗种密度过低，生长速度相对较快，但是单位产量低，经济效益不理想；三是通过这种传统养殖方式产出的生蚝，形态各异，外观参差不齐，单价较低。为此，如何创建一套根据养殖容量控制养殖密度的养殖模式至关重要，从而来加快生长速度、提高存活率、提高单位产量、改变牡蛎外部形态，提高单价。Hong Kong oysters have a history of nearly a thousand years of cultivation in my country, and the main cultivation methods are divided into tidal flat planting, sinking row cultivation, raft suspension cultivation, scaffold cultivation and other types. Among them, floating raft and sinking are the two most important farming methods. In the past, oyster farmers used wild seedlings for cultivation. Among them, there are some problems, the first is that if the seedling density is too high, its growth rate will be relatively slow, the breeding season and winter mortality will be high, and the breeding cycle will be long; the 2nd, if the seedling density is too low, the growth rate will be relatively fast , but the unit yield is low, and the economic benefits are not ideal; third, the oysters produced by this traditional farming method have different shapes and appearances, and the unit price is relatively low. For this reason, how to create a culture model that controls the culture density according to the culture capacity is very important, so as to speed up the growth rate, improve the survival rate, increase the unit yield, change the external shape of oysters, and increase the unit price.
发明内容：Invention content:
本发明的目的是针对当前香港牡蛎养殖技术中存在的单产量较低、单价不高等缺陷，提供一种实用性强，单产高、效益好的提高香港牡蛎养殖效益的单体连接养殖方法。The object of the present invention is to provide a kind of monomer connection cultivation method with strong practicability, high per unit yield and good benefit to improve the benefit of Hong Kong oyster cultivation in view of the defects such as low unit yield and low unit price existing in the current Hong Kong oyster cultivation technology.
本发明构建了单体连接养殖方法来提高香港牡蛎经济效益，通过获取单体、单体连接、单体养殖等环节，加快了生长速度、提高了单产及其单价，为香港牡蛎产业稳定快速发展提供了坚实的基础，从而实现了本发明的目的。The present invention constructs a monomer connection culture method to improve the economic benefits of oysters in Hong Kong. Through the acquisition of monomers, monomer connection, monomer cultivation and other links, the growth rate is accelerated, the unit yield and unit price are improved, and it contributes to the stable and rapid development of the Hong Kong oyster industry. A solid foundation is provided, thereby realizing the purpose of the present invention.
本发明的提高香港牡蛎经济效益的单体连接养殖方法，其特征在于，包括以下步骤：The monomer connection culturing method of improving Hong Kong oyster economic benefit of the present invention is characterized in that, comprises the following steps:
在秋冬季节，以防嗮、防雨、通风较好的平整地面作为工作场所，选择壳高≥30mm的单体香港牡蛎作为连接对象，每条苗绳的长度控制在1.6-2.5米，每条苗绳上设置8～15个粘着点，每两个粘着点之间的间距为10～15cm，以单体香港牡蛎的左壳为粘着点，以水泥作为粘着剂，将单体香港牡蛎的左壳粘附在苗绳的粘着点上，每个粘着点粘附2～6个单体香港牡蛎，粘附时牡蛎壳高方向与苗绳平行，牡蛎壳长方向与苗绳垂直，壳顶在下，或者牡蛎壳高方向与苗绳垂直，壳长方向与苗绳平行，然后阴凉处放置，待水泥干硬后，苗绳以及粘着在苗绳上的香港牡蛎吊养在浮筏或者沉排上进行养殖。经过一周年的养殖，可达到上市规格。In the autumn and winter seasons, use a flat ground that is anti-sunshine, rain-proof, and well-ventilated as the workplace, and choose a single Hong Kong oyster with a shell height ≥ 30mm as the connection object. The length of each seedling rope is controlled at 1.6-2.5 meters. Set 8 to 15 adhesion points on the seedling rope, and the distance between every two adhesion points is 10 to 15 cm. The left shell of the single Hong Kong oyster is used as the adhesion point, and cement is used as the adhesive. The shells are attached to the sticking points of the seedling rope, and each sticking point sticks 2 to 6 single Hong Kong oysters. When sticking, the height direction of the oyster shell is parallel to the seedling rope, the long direction of the oyster shell is perpendicular to the seedling rope, and the top of the shell is on the bottom. , or the oyster shell height direction is perpendicular to the seedling rope, and the shell length direction is parallel to the seedling rope, and then placed in a cool place. After the cement is dry and hard, the seedling rope and Hong Kong oysters attached to the seedling rope are suspended on floating rafts or sunken rows. To breed. After one year of breeding, it can reach the market size.
所述的牡蛎壳高方向与苗绳垂直，壳长方向与苗绳平行，优选，此时每个粘着点限两个单体香港牡蛎，两个单体香港牡蛎的壳顶相对放置。The height direction of the oyster shell is perpendicular to the seedling rope, and the shell length direction is parallel to the seedling rope. Preferably, at this time, each adhesion point is limited to two single Hong Kong oysters, and the shell tops of the two single Hong Kong oysters are placed oppositely.
所述的壳高≥30mm的单体香港牡蛎优选为壳高为30～100mm的单体香港牡蛎。The single Hong Kong oyster with a shell height ≥ 30 mm is preferably a single Hong Kong oyster with a shell height of 30-100 mm.
选择在秋冬季节操作，是因为此时的牡蛎处于生长期(非繁殖期)进行，此时温度较低，有利于牡蛎长期露空放置，存活力高。Choose to operate in autumn and winter because the oysters are in the growth period (non-breeding period) at this time, and the temperature is low at this time, which is conducive to long-term open air storage of oysters and high viability.
在将单体香港牡蛎粘着苗绳上时，要注意水泥不要将单体香港牡蛎的两壳粘住，导致其无法张开双壳进行率水呼吸摄食，如发现有此种现象，立即清除掉粘住双壳部位水泥即可；再有所使用的单体，如果有损伤，将其放置于正常海水中3-7天后再使用，既可以回避损伤，防止个体死亡。When sticking the single Hong Kong oyster to the seedling rope, pay attention to the cement not to stick the two shells of the single Hong Kong oyster, so that it cannot open the double shell for water breathing and feeding. If this phenomenon is found, remove the sticking immediately Cement is sufficient for the double shell; if there is any damage to the monomer used, place it in normal sea water for 3-7 days before using it, which can avoid damage and prevent the individual from dying.
本发明通过获取单体、单体连接、单体养殖等技术环节，构建了一套提高香港牡蛎经济效益的单体连接养殖技术工艺，克服了过去利用天然苗种进行养殖过程中存在的苗种密度过大生长缓慢、死亡率高；苗种密度过低浪费养殖区使用面积、单位产量低等缺陷。本发明不但获得了外观整齐一致的商品蚝，提高牡蛎单价20-30％，还可以有效的根据养殖容量控制养殖密度，加快生长速度80-120％，提高单位产量10-15％，提高经济效益60％以上，这为香港牡蛎健康养殖产业可持续发展提供了新途径。本发明具有实用性强，易于推广等优点。The present invention builds a set of monomer connection cultivation technology process to improve the economic benefits of Hong Kong oysters by obtaining monomers, monomer connection, monomer cultivation and other technical links, and overcomes the seedlings that existed in the cultivation process of using natural seedlings in the past. If the density is too high, the growth rate is slow and the mortality rate is high; if the seedling density is too low, the use area of the breeding area is wasted, and the unit yield is low. The invention not only obtains commercial oysters with uniform appearance, increases the unit price of oysters by 20-30%, but also can effectively control the breeding density according to the breeding capacity, speed up the growth rate by 80-120%, increase the unit output by 10-15%, and improve economic benefits More than 60%, which provides a new way for the sustainable development of the healthy oyster farming industry in Hong Kong.

在整个单体连接过程中，共计连接4.0万条，利用了20天时间，每天都是20个工人，每人每天可以连接100条左右。需要注意的是，水泥不要粘住牡蛎左右壳，使其无法张开双壳呼吸摄食，会被活活憋死。其中，大约有18000个左右破损个体，经过在海水中放置7天，贝壳基本愈合，之后都进行单体连接，存活率在90％以上。During the entire monomer connection process, a total of 40,000 pieces were connected, and it took 20 days. There were 20 workers every day, and each person could connect about 100 pieces per day. It should be noted that the cement should not stick to the left and right shells of the oyster, so that it cannot open the double shells to breathe and feed, and it will be suffocated to death. Among them, there are about 18,000 damaged individuals. After being placed in seawater for 7 days, the shells are basically healed, and then they are all connected to the monomers. The survival rate is over 90%.
2014年10月，经过12个月养成，单体香港牡蛎达到上市规格，相对于传统养殖方法而言，单体连接养殖模式在大风江养殖区，单位产量由原来的30吨/沉排增加至40吨，单个个体大小由原来平均100-150g/个增长至200-300g/个，单价由原来的6.0元/kg增加至8.0元/kg，整体水平上经济效益增加了77％。In October 2014, after 12 months of cultivation, the individual Hong Kong oysters reached the market specification. Compared with the traditional farming method, the unit output of the single connected culture mode in the Dafengjiang breeding area increased from the original 30 tons/sinking row To 40 tons, the size of a single individual increased from the original average of 100-150g/piece to 200-300g/piece, the unit price increased from the original 6.0 yuan/kg to 8.0 yuan/kg, and the overall economic benefit increased by 77%.
