Comparative studies on life history parameters of coastal fishes among different regions of Taiwan

Chang, Yen-wei 29 August 2007 (has links)
A total of 840 fish species names (belonging to 143 families) were gathered from the Taiwan coastal area-economic geographical database. [http://fishdb.sinica.edu. tw/ 2001new/main1.asp] The near-shore area of Taiwan were divided into eight areas for studies of geographical distribution and biodiversity pattern. Biological data for individual species was gathered from ICLARM (Fishbase) including trophic level and VBGF growth parameters. The temporal and spatial difference between different areas were studied using traditional statistical methods and S-P chart analysis. The results show that Eastern area has higher trophic level , asymptotic length (L¡Û) , maturity length (Lm) , age at maturity (Tm) and Maximum age (Tmax) than the West. Also the Eastern has relatively lower food items on plant , M value and K values. Presence and absence of fish species were organized and presented into the so-called S-P chart for demonstrating the interaction between species or family diversity and habit. Results on family level show that the West has greatest species richness (96 families) in contrast to the North-West and South-East (69 families).A total of 29 families distributed at all areas, whereas fishes belonging to the other 22 families can only be found on one single area. Results on species level show that the West has greatest species richness (538 species) in contrast to the North-West (207 species).Result from the S-P chart also serves for statistical testing in identifying the significance difference on species-habit interactions among different area of fish populations. Cluster analysis show that North-East , East and South-East can be grouped into one group. The other individual groups were North-West , West , South-West , North and South.
