漁業崩落 Fishing down (MA 2005)
Mean trophic levels of fisheries products= FAO FISHSTAT + FISHBASE
It does not mean indicator of overfishing Japanese MTL is high

Catch and mean trophic level in Japan(Matsuda et al. 2010 Ecol Res)
CoFRaME
…mean trophic level (MTL) from catches … underpins reported trends in human impacts, declining when predators collapse ("fishing down marine food webs") and when low-trophic-level fisheries expand ("fishing through marine food webs"). The assumption is that catch MTL measures changes in ecosystem MTL and biodiversity. Here we combine model predictions with global assessments of MTL from catches, trawl surveys and fisheries stock assessments and find that catch MTL does not reliably predict changes in marine ecosystems. Instead, catch MTL trends often diverge from ecosystem MTL trends obtained from surveys and assessments. …To detect fishing impacts on marine biodiversity, we recommend greater efforts to measure true abundance trends for marine species, especially those most vulnerable to fishing.

CoFRaMEConclusion
Huge data from Fishing Vessel Monitoring Systems (VMS) are compiled;
Biological database (FISHBASE, OBIS…) are useful, combined with…
Global and Japanese catch statistics data (FISHSTAT, ) , and
Mathematical analysis and good idea!
