Im Curriculum der tierärztlichen Ausbildung sind Lehreinheiten zu Kommunikations- und Beratungsstrategien speziell in der Nutztierhaltung derzeit nicht vorgesehen. Da die Tierärztin und der Tierarzt meist als erste bei Problemen auf dem Betrieb von den Tierhaltenden angesprochen werden, können durch sie Veränderungen bewirkt werden, sofern sie entsprechend ausgebildet sind.

Über ein zweistufiges, innovatives Lehrkonzept, soll Studierenden der letzten Fachsemester, während der Lehreinheit "Epidemiologie und Bestandsdiagnostik beim Schwein" vermittelt werden, wie sie 1. das landwirtschaftliche Personal über ein Gespräch erreichen, zur Selbstreflexion bewegen und damit einen positiven Veränderungsprozess für die Betriebsabläufe anstoßen können und 2. ihre eigene Tierbeobachtung im Betrieb schulen und diese mit dem landwirtschaftlichen Personal kommunizieren.

Der letzte Teil des Projektes umfasst die Evaluation der Lehrveranstaltung in Bezug auf ihre Wirksamkeit auf Betriebsebene: Hat die Beobachtungs- und Kommunikationsstrategie der Studierenden unter Anleitung eines tierärztlich erfahrenen Lehrenden zu einer Verbesserung der Tiergesundheit und des Tierwohls geführt?

Project Details:
Harbor porpoises are representatives of the top predators from the group of mammals in the North Sea and Wadden Sea. With the amendment of the National Park Act in 1999, part of the national park was explicitly dedicated to harbor porpoise protection, as a high density of mother-calf groups was found there. As part of the reorganization of the Federal-Länder Marine Program (BLMP), a program for joint monitoring of marine mammals was agreed upon in January 2011, which meets the requirements of monitoring according to the relevant European guidelines and international conventions. In this program, the Schleswig-Holstein National Park Administration (NPV) within the Schleswig-Holstein State Agency for Coastal Protection, National Parks and Marine Conservation (LKN) has the task of organizing, implementing and financing the acoustic monitoring of harbor porpoises. The acoustic surveys for the NPV are conducted by the Institute for Terrestrial and Aquatic Wildlife Research (ITAW) as part of the joint marine mammal monitoring under the BLMP. For this purpose, monitoring stations are operated at four specified locations in the Schleswig-Holstein Wadden Sea (Lister Tief, Meldorfer Bucht, Rochelsteert, and Westerland). The monitoring stations are equipped with click detectors (C-PODs), which record the echolocation activity of harbor porpoises. The C-PODs are maintained and read out on a regular basis. The data obtained will be evaluated against the background of the optimization of the acoustic monitoring as well as necessary extensions in case of a permanent operation of the monitoring stations. The data of this long-term study provide information about a possible rhythmicity as well as tidal dependence in the porpoise detection over the day and over the course of a year.

Results:

The analysis of the data showed that harbor porpoises have been recorded at all four monitoring positions over the study period to date. However, spatial (between stations) and temporal differences (individual years, over the course of a year, over the course of a day) in detection rates were noted. At the station Lister Tief (LT), on the eastern side of Sylt, the lowest detection rates were recorded. The station Westerland (WL), west of Sylt in the whale sanctuary, has the highest detection rates (maximum per day) over the study period. The station Meldorfer Bucht (MB), which is located in the immediate vicinity of Büsum harbor, also showed very high detection rates, with an increasing trend in the summer months. The modeling of the individual stations could clearly show that there is a strong seasonality in the harbor porpoise detections. All stations show a maximum in detections in spring, in the period from mid-March to mid-April. This period is just before the phase of the highest birth rate, which lasts from mid-June to the end of July. During this period, increased detections were only detected at station MB. Approximately two months after the birthing phase, the mating season of harbor porpoises in the North Sea begins. Within this period, an increased detection was observed at Rochelsteert station (RS) in contrast to all other stations. This could be an indication that the area around the station is used for mating. The calves are suckled for about 10 months, but start eating solid food, in the form of small shrimp-like crabs (Euphausiidae, e.g., North Sea shrimp), at about five months of age. During this stage, an increase in detection rates was noted at Station LT. It is conceivable that juvenile harbor porpoises visit shallow water areas, such as at station LT, to seek benthic first solid food.

 

Time of day had little effect on detection rates over the entire study period. However, a pattern in diurnal rhythms with more frequent detections in the morning hours was observed at Station LT. A similar pattern was also evident at station RS, with slightly higher detections, spread throughout the day.

The influence of the tide is more pronounced than the diurnal rhythmicity and could be observed at high tide or in the phases between high and low tide. Station LT shows increased detection rates just before low water and a minimum during high water. When comparing stations WL and RS with MB, an opposite effect is observed. Station MB shows a minimum in detection rates shortly after high tide, which translates into a maximum during high tide at stations WL and RS.

 

The Wadden Sea monitoring has so far generated robust and continuous long-term data sets of nine years of harbor porpoise click activity. With these unique data sets, it is possible to build models that provide information on harbor porpoise presence in the Wadden Sea and the influence of possible environmental parameters. The increase of the data base over the years has shown that the models provide an increasingly clear picture of the influence of abiotic factors on harbor porpoises. The assessments of harbor porpoise presence required by international agreements (MSFD and trilateral agreements) can currently only be carried out on a temporal scale using the acoustic data generated within the project with click detectors. In order to further expand the data base and thus improve the quality for assessment, it is necessary to continue the Wadden Sea monitoring every year.
