Estimating end effects in trawl catches

Estimating catches with automatic identification system (AIS) data: a case study of single otter trawl in Zhoushan fishing ground, China

The sailing tracks of single otter trawl vessels were simulated using cubic hermite spline (cHs) interpolation method based on the automatic identification system (AIS) data of 6 sampled vessels that were fishing in the Zhoushan fishing grounds after the close of the fishing season from September 2012 to January 2013.  The vessels’ status (i.e. whether the vessels were fishing or not) were dete...

Environmental DNA from Seawater Samples Correlate with Trawl Catches of Subarctic, Deepwater Fishes

Remote polar and deepwater fish faunas are under pressure from ongoing climate change and increasing fishing effort. However, these fish communities are difficult to monitor for logistic and financial reasons. Currently, monitoring of marine fishes largely relies on invasive techniques such as bottom trawling, and on official reporting of global catches, which can be unreliable. Thus, there is ...

Estimating End-to-End Cell Delay Variation in ATM Networks

Cell delay variation (CDV) is one of the quality of service parameters that can be negotiated between applications and an ATM network. The network should check during connection setup, as part of call admission control, whether it can satisfy the requested CDV of an application. For this comparison, the network should estimate the end-to-end CDV that it can support, by using local information a...
