随着“北参南移”养殖技术的突破,福建海参养殖业发展迅速.但由于福建市场的海参产品大多属于传统的粗加工产品,产品形式较单一、科技含量低、附加值不高.不仅无法实现海参产品的经济价值,而且严重阻碍了海参产业持续、稳定、健康的发展.本文通过对福建海参加工产业现状的深入分析,提出了加工产业存在的主要问题:缺少品牌意识、忽略地方特色和产品优势、深加工技术不足、加工流程不规范、企业市场竞争无序及产品质量良莠不齐等.在此基础上,综述了以整合海参产业、关注产业发展定位、增加产业附加值以及深入挖掘海参食文化内涵和外延等推进福建海参产业发展的具体措施. 相似文献

Consumption and Assimilation of Salmon Net Pen Fouling Debris by the Red Sea Cucumber Parastichopus californicus: Implications for Polyculture 总被引：1，自引：0，他引：1
Abstract Fouling debris composed of fish feces, excess fish food, algae, and other particulate organic matter can create environmental problems for aquaculture facilities that rear fish in ocean net pens. Accumulations of organic debris can clog the nets and restrict water circulation which in turn can stress fish. Experiments in which red sea cucumbers Parastichopus californicus were allowed to feed inside floating net pens at a salmon rearing facility in Southeast Alaska showed that sea cucumbers consumed fouling debris and cleared a significant amount of surface area on the nets (P < 0.0001). Sea cucumbers assimilated amino acids and other organic matter from fouling debris two to three times more efficiently than from their natural sediment diet. Muscle development of sea cucumbers consuming fouling debris inside the net pens was also significantly greater than that of sea cucumbers feeding in their natural environment (P < 0.0003). This work suggests that polyculture operations in which commercially important detritivores, like the red sea cucumber, are grown in net pens along with salmon could possibly convert the net from self-fouling to self-cleaning and could turn fouling debris into a marketable product (sea cucumber biomass). 相似文献

Stable carbon and nitrogen isotope ratios (δ13C/δ15N) were assessed as a means to ascertain the recent in situ feeding history of the common New Zealand sea cucumber Australostichopus mollis in relation to nutrient enrichment from a longline green‐lipped mussel (Perna canaliculus) farm in Northern New Zealand. δ13C and δ15N isotopic signatures and the ratios of sea cucumbers sampled from within the impact footprint of the mussel farm were compared with those of sea cucumbers residing on adjacent natural reefs. Sea cucumbers from beneath mussel farming longlines had significantly different δ13C stable isotope signatures in comparison with sea cucumbers collected from neighbouring natural reef habitats. This difference supports the hypothesis that sea cucumbers in the same bay maintain distinctly different feeding histories, with those residing beneath mussel farming longlines deriving tissue carbon from sediment impacted by farming activities. This hypothesis is further supported by the finding that the isotope signature of sediment collected from beneath the mussel farm is consistent with the expectation that sea cucumbers were feeding on and consuming sediment enriched with bivalve waste (faeces and pseudo‐faeces). In contrast, the nitrogen stable isotope signature (δ15N) was found to be similar between sites for both sea cucumbers and assumed food sources. Both findings lend support to the viability of future sea cucumber/green‐lipped mussel farm polyculture systems. Sea cucumbers in different locations (mussel farm, natural reef) possessed distinctly different isotope signatures, suggesting that mixing of sea ranched sea cucumbers with natural reef populations would be negligible or non‐existent. Similarities between the isotope signatures in low metabolic tissue of sea cucumbers residing at the mussel farm site to that of mussel farm‐impacted sediment suggest that cucumbers beneath mussel farms appear to have high rates of retention at the farm site. 相似文献

研究了不同饲料原料对刺参Apostichopus japonicus(Selenka)幼参生长和体成分的影响.实验采用鱼粉、鼠尾藻Sargassum thunbergii Kuntze、浒苔Enteromorpha prolifera、海带Laminaria japonica和海泥5种主要原料配制的饲料投喂体长为4.18±0.23cm、体重为5.99±0.26g的刺参幼参,进行了为期80d的养殖实验.实验结束时,投喂鼠尾藻饲料、浒苔饲料和动物性饲料的刺参特定生长率(SGR)分别为95.36%/d、92.29%/d和84.87%/d.这三者之间无显著差异,但生长效果要好于投喂海带饲料和海泥饲料的刺参.实验结果表明,在特定的室内养殖条件下,虽然刺参能够更好地利用植物性蛋白,但是可以将动物性蛋白作为刺参的辅助性饲料成分,配制出营养更全面的配合饲料;浒苔作为刺参幼参的养殖饲料原料是完全可行的;海带粗加工产品不适于用做刺参饲料的主要成分. 相似文献

The effects of four modes of diel temperature-fluctuation with two designated fluctuating temperatures (15 ± 3°C and 18 ± 3°C)
on the growth and energy budget of young sea cucumber, Apostichopus japonicus Selenka, were studied to develop a highly efficient temperature-control scheme for aquaculture of the species. Sea cucumbers
with a mean wet body weight of 8.0 ± 1.2 g (mean ± SD) were allocated to each treatment randomly with five replicates. After
a 38-day trial, specific growth rate (SGR) and food conversion efficiency (FCE) decreased with increasing temperature in constant-temperature
treatments. Among the four modes of temperature fluctuation, SGR of sea cucumbers reared under a mode which simulated the
natural fluctuation of the temperature (mode C) of seawater was significantly higher than that of sea cucumbers reared at
the corresponding constant temperatures. This enhancement of growth rate by use of mode C was attributed to higher FCE and
lower energy allocated to respiration and feces. In large-scale culture, a temperature-control mode designed based on mode
C could enhance not only growth but also efficiency of food utilization by the young sea cucumber. 相似文献

国内外海参自然资源、养殖状况及存在问题 总被引：49，自引：6，他引：43
海参含有丰富的蛋白质和黏多糖,营养和药用价值极高。自20世纪80年代以来,海参的几种重要商业品种的苗种培育在日本、中国和印度等国家相继获得成功。近年来,海参消费需求的逐步扩大导致世界范围内海参自然资源的过度开发和种群数量的急剧下降,海参的人工养殖随之兴起。目前,国内海参养殖规模不断扩大,养殖方式多种多样。然而养殖的过速发展和不规范运作也造成了如生态环境恶化、病害等诸多问题。本文综述了国内外海参的自然资源、种群分布,以及目前海参主要养殖品种的苗种培育和增养殖技术要点,就海参养殖中存在的主要问题进行了探讨并提出了相应的对策。 相似文献

The feasibility of co‐culturing the sea cucumber Holothuria leucospilota Brandt in a subtropical fish farm was investigated in a field study. Sea cucumbers were cultured in the fish farm in cages suspended at 4 m deep (suspended culture) and directly on the seafloor (bottom culture). The survival and growth of the sea cucumbers were monitored twice during the 3‐month, summer experimental period (May 26–August 14, 2010). Results showed that the suspension‐cultured sea cucumbers exhibited excellent survival rate (100%) during the whole study period. There also occurred no mortality in the bottom‐cultured sea cucumbers during the first culture period (May 26–July 13); but all these died from anoxia caused by water column stratification during the second culture period (July 14–August 14). The specific growth rate of the bottom‐cultured sea cucumbers (1.05 ± 0.21 % day?1) was nearly double that of the suspended culture animals (0.57 ± 0.21 % day?1) during the first culture period, and the growth rates of the suspended culture sea cucumbers in the second culture periods (0.46 ± 0.24 % day?1) was only a little lower than that of the first period. The sea cucumbers H. leucospilota could ingest and assimilate sediment with high organic matter content with an average assimilation efficiency of 14.9 ± 3.9%. This study indicated that fish farm detritus can be effectively used as a food source for the sea cucumber and that it can be turned into a valuable secondary crop in the form of the sea cucumber biomass. 相似文献
