Abstract

Abstract Collectively known as eucheumatoids, Eucheuma denticulatum, Kappaphycus alvarezii, K. malesianus, and K. striatus are the main farmed seaweed species in the Philippines. The success of seaweed farming for over five decades in the country is due, in part, to the high diversity of cultivars maintained by the Filipino farmers. Notwithstanding the fact that many eucheumatoid cultivars are presently (and consistently) recognized by the Filipino farmers, there has been no attempt to summarize the current state of the local traditional knowledge about the diversity of this seaweed group, especially with reference to the taxonomy, cultivar designation and distribution. Factors based on present day local knowledge on the eucheumatoid cultivars and what is known on genetic identification in the Philippines were also discussed. A total of 66 cultivars recognized across 58 provinces in the Philippines were documented. Most of these cultivars were morphologically identified as either K. alvarezii or K. striatus, however, the majority were yet to be genetically identified. In part, due to higher demand of kappa-carrageenan extract as compared from the iota type, K. alvarezii and K. striatus were widely cultivated in the Philippines than that of E. denticulatum. Only in the southern Philippines that K. malesianus is currently cultivated. The diverse cultivars identified in this study suggest that the Filipino farmers possess important traditional knowledge that can be useful for future crop selection and breeding.
菲律宾Eucheumatoid海藻品种的多样性
摘要统称为Eucheumaids、Eucheuma denticulatum、Kappaphycus alvarezii、K.malesianus和K.striatus是菲律宾主要的养殖海藻物种。该国50多年来海藻养殖的成功,部分归功于菲律宾农民保持的品种多样性。尽管菲律宾农民目前(并一贯)认可了许多桉树品种,但没有人试图总结当地关于该海藻群多样性的传统知识的现状,特别是在分类学、品种名称和分布方面。还讨论了基于目前当地对桉树品种的了解以及菲律宾已知的遗传鉴定的因素。菲律宾58个省共有66个品种被确认。这些品种中的大多数在形态上被鉴定为A.alvarezii或A.striatus,然而,大多数还没有被基因鉴定。在一定程度上,由于与iota型相比,对kappa卡拉胶提取物的需求更高,在菲律宾,A.alvarezii和K.striatus比E.denticulatum广泛种植。目前只有在菲律宾南部才有马来金龟子栽培。本研究中确定的不同品种表明,菲律宾农民拥有重要的传统知识,可用于未来的作物选择和育种。

期刊介绍: Reviews in Fisheries Science & Aquaculture provides an important forum for the publication of up-to-date reviews covering a broad range of subject areas including management, aquaculture, taxonomy, behavior, stock identification, genetics, nutrition, and physiology. Issues concerning finfish and aquatic invertebrates prized for their economic or recreational importance, their value as indicators of environmental health, or their natural beauty are addressed. An important resource that keeps you apprised of the latest changes in the field, each issue of Reviews in Fisheries Science & Aquaculture presents useful information to fisheries and aquaculture scientists in academia, state and federal natural resources agencies, and the private sector.
