    The pelagic freezer trawler fishery targets small pelagic species. The economically most important species are: herring (Clupea harengus), blue whiting (Micromesistius poutassou), horse mackerel (Trachurus trachurus), mackerel (Scomber scombrus), greater argentine (Argentina silus) and pilchard (Sardina pilchardus). The annual landings of this fishery follow seasonal patterns; different species are targeted during different parts of the year. The total landings of these target species by the Dutch fleet operating in European waters of were about 245,000 tonnes in 2017 and about 303,000 tonnes in 2018. The total landings of these target species by the German fleet operating in European waters were about 124,000 tonnes in 2017 and about 129,000 tonnes in 2018. Herring, blue whiting, mackerel and horse mackerel were the most abundant landed species. In the European Union the collection and management of fisheries data is regulated through the Data Collection Framework (DCF) of the European Commission (EC). Within this context, from 2002 onwards catches of the European freezer trawler fleet are sampled by the Netherlands and Germany through two separate observer programmes. A process to harmonize the pelagic on board sampling programmes has started a few years ago and is still continuing. This report presents a summary of the data collected in the two monitoring programmes in European waters during the period 2017 and 2018. The two programmes together correspond with a sampling coverage of around 15% and 11% of the total Dutch and German flagged pelagic freezer trawler fleet effort (expressed in number of trips) in European waters in 2017-2018, respectively. An important element in the reform of the Common Fisheries Policy (CFP) is the obligation to land all catches, i.e. the landing obligation. Consequently, from 2015 onwards the European pelagic freezer trawler fishery is in principle obliged to keep catches of quota regulated species on board. This has affected the sampling protocols and procedures; sampling has shifted from discards monitoring towards catch monitoring. Furthermore, the CFP also introduced the concept of regionalisation, meaning that Member States which share a fishing area should work together in collecting, managing and making the data available for scientific advice. Regionalisation of data collection was established during the recast of the Council Regulation describing the DCF (EU 2017/1004). Ultimately, under regional sampling, the Dutch and German pelagic sampling programmes are expected to merge together or at least be completely harmonised and thus interchangeable. Currently, the EU regional coordination group for the North Sea/Eastern Arctic & North Atlantic is working on a regional sampling plan for the freezer trawler fleet exploiting pelagic fisheries in the Northeast Atlantic.

    OBJECTIVE To investigate whether body mass index (BMI) is a prognostic factor for biochemical recurrence (BCR) in Dutch men after radical prostatectomy (RP), as although epidemiological studies of obesity in relation to prostate cancer have provided conflicting results, recent studies from the USA suggest that a higher BMI is a risk factor for progression of prostate cancer. PATIENTS AND METHODS Of the 1417 patients with prostate cancer who had RP at two University hospitals, 1302 were included in the present study. BMI (kg/m(2)) classes were defined as normal (<25), overweight (25-30) and obese (>= 30). The median follow-up was 59 months and clinical data were obtained retrospectively from charts. BCR was defined as two consecutive prostate-specific antigen (PSA) levels of > 0.1 ng/mL. RESULTS In all, 600 patients were classified as having normal weight (43.9%), 665 as overweight (48.6%) and 103 as obese (7.5%). Overall, 297 patients developed BCR after RP; the 10-year risk (95% confidence interval) of BCR was 31.9 (26.6-37.2)%, 30.5 (25.8-35.2)% and 23.9 (14.9-32.9)% for patients in the three categories, respectively (P = 0.836). Multivariable proportional hazard regression analyses of BMI and established prognostic factors for BCR did not change these results. CONCLUSION BMI appeared to have no prognostic value for BCR in Dutch patients with clinically localized prostate cancer and treated with RP.

    1. In sheep, provided with re-entrant cannulas in the caudal duodenum and with an infusion tube into the abomasal fundus, emptying of the liquid phase of the abomasal contents was studied with [57Co]EDTA. Radioactivity was measured continuously with Geiger-Müller counters placed along the re-entrant cannulas. 2. It appeared that first-order kinetics could be applied to the elimination of [57Co]EDTA from the abomasum. Mean retention time of this label in the abomasum was 40–50 min. 3. Infusion of a suspension of soya-bean protein in saline (9 g sodium chloride/l) caused an initially decreased rate of abomasal emptying, but after 48 h an adaptation had occurred to the original rate of emptying producing an increased volume of abomasal contents and increased flow-rate of digesta into the duodenum.
