Fishing Vs. Climate Change: An Example Of Filefish (Thamnaconus Modestus) In The Northern East China Sea, Sukgeun Jung, Hyung Kee Cha Dec 2013

Fishing Vs. Climate Change: An Example Of Filefish (Thamnaconus Modestus) In The Northern East China Sea, Sukgeun Jung, Hyung Kee Cha

Journal of Marine Science and Technology–Taiwan

The main cause of annual fluctuations in catch and species composition of fisheries is usually uncertain, but a prevailing view has been that fishing effects are more critical than environmental variability. Filefish is a good anecdote: many Korean fisheries scientists have attributed the sudden collapse of Korean filefish fisheries in the early 1990s to overfishing, especially by trawl fisheries in the northern East China Sea (NECS). However, interdisciplinary researches have revealed that climate-driven, multi-decadal variability in oceanic conditions impacts both fish and fisheries around the world. To test the two alternative hypotheses (i.e., fishing and climate) as the major cause …

Bacterial growth rates were determined in natural seawater samples using two different methodological approaches: incubation in dialysis bags, and a modification of the dilution approach. Bacterial growth rates estimated for the dialysis bag varied from 0.026 h-1 (April) to 0.208 h-1 (August). Bacterial growth rates in 0.2 µm and 30 kDa size-fractionated series ranged from 0.038 to 0.094 h-1 and 0.078 to 0.42 h-1, respectively. Furthermore, in all of our samples, growth rates in the 30 kDa fractionated series (grazer and virus-free diluent) were higher than in the 0.2 µm series (grazer-free diluent) or in the dialysis bag incubations.
