Animal welfare and animal health are increasingly becoming the focus of research and consumer attention. As a result, there are calls in many areas for a central animal health database. Standardized data collection already exists in numerous areas, but there is no central database or comprehensive evaluation. For the first time, data from cattle farms that are members of Qualität und Sicherheit GmbH from 2023 and 2024 will be evaluated jointly. The data comes from the areas of biosecurity, animal husbandry, antibiotic use and slaughter findings. For joint evaluation, the data is first linked and evaluated descriptively.

Title: Scientific investigation of seals released in accordance with animal welfare regulations, especially with regard to infectious diseases and zoonotic pathogens, as well as the scientifically based further training of personnel of the stranding network for the North and Baltic Seas of Schleswig-Holstein
The harbor seal is the most common marine mammal species in Schleswig-Holstein and causes the most call-outs for seal hunters. In the last three decades, seal populations have experienced several major epizootics, but have subsequently grown in size again. In recent years, however, it has been observed that this growth has stagnated and younger seals in particular are disappearing from the populations.
Seals can be carriers of infectious agents such as the Phocine distemper virus, influenza viruses, brucella and erysipelas, some of which can have fatal consequences for the individual animal or the population. These infectious agents are often zoonotic in nature and can promote secondary infections with other pathogens such as Bordetella bronchiseptica or toxoplasmosis.
In addition to comprehensive pathological examinations of the seals, microbiological, virological and parasitological examinations will also be carried out in this project.
Particular attention will be paid to the young animals in order to check whether there may be health related reasons for their decline. For this purpose, a representative number of all seals handed in by seal hunters from the North and Baltic Seas will be selected and subjected to complete post-mortems and further examinations.
The scientific findings will be directly incorporated into the work of the seal hunters, who will receive regular training in the detection of diseases and the handling of marine mammals. Hygiene measures and documentation materials will be developed and reviewed, and accident prevention training will be provided. To this end, a scientific exchange with the seal hunters will take place throughout the entire research project period.
The occurrence of infectious diseases such as brucellosis, erysipelas, bird flu and phocine distemper and the occurrence of the causative pathogens will be investigated. The focus is the assessment of the seals health status and the zoonotic potential of the infectious agents detected with regard to a possible risk of infection for the seal hunters and collectors involved in the stranding network. Seal hunters and collectors are therefore trained in the detection of infectious diseases, hygiene concepts, assessment of health conditions and accident prevention.

The aim of the project is to process the survey data from the summer period and aggregate the quality-checked data for the Belt-Sea-Region in the period 2005-2024; or a period close to that depending on data and model checking. An extraction of relevant environmental covariates, describing the habitat of harbour porpoises, and a fit of a species distribution model (generalized additive model GAM) is planned. The final selected model enables the spatial prediction of the harbour porpoise summer density in the study area. Subsequently, a model validation, estimation of the model error and confidence intervals is planned. Finally, a short technical report will be written to describe the method and the results with a focus on Danish Belt-Sea-Region.

Since 2002, ITAW has been conducting aerial surveys for harbour porpoises in the EEZ and the 12sm zone of the German North Sea. A dedicated monitoring of harbour porpoises in the North Sea and Baltic Sea has been carried out in projects of the Federal Agency for Nature Conservation (BfN) since 2008. Within the framework of this survey and monitoring, valuable data series on the spatio-temporal occurrence and density of harbour porpoises could be collected including the area of the whale sanctuary in the Schleswig-Holstein Wadden Sea National Park.
ITAW also has proven expertise in bioacoustics and acoustic monitoring of cetaceans. Porpoise click detectors (PODs) have already been used in numerous projects to study harbour porpoise habitat use. The LKN POD monitoring has been operated by ITAW since 2011 and data on acoustic harbour porpoise activity could also be collected in the area of the whale sanctuary in the Schleswig-Holstein Wadden Sea.
The aim of the project is to update a previous report on the importance of the small whale sanctuary as a habitat for harbour porpoises for feeding and as a calving and breeding area, using most recent data.

Recently, there has been an increase in strandings of sea turtles on the Schleswig-Holstein coast. Between 2022 and 2024, a total of five animals have stranded so far. The loggerhead turtle, leatherback turtle and Atlantic bastard turtle were found.
The reasons for the current increased occurrence of sea turtles in the North Sea are not known. In general, the water temperatures here are too cold for the animals, especially in winter. As a result, the animals enter a state of rigidity, as reptiles are highly dependent on the ambient temperature. In this state, the animals can no longer move actively and drift with the current. The recent increase in the number of finds could indicate a new trend, but this will have to be confirmed over the next few years. However, due to the expected rise in temperature as a result of climate change, a more frequent occurrence of these sea creatures on our coasts seems likely in the long term.
The main aim of this pilot study is to collect data on the occurrence of sea turtles on the coasts of Schleswig-Holstein. Dead stranded sea turtles will be dissected at the Institute for Terrestrial and Aquatic Wildlife Research (ITAW) in order to uncover the causes of stranding and the incidence of disease.
The project is divided into the following five subsections.
1. data collection: Data on sea turtles stranded on the Schleswig-Holstein coast will be collected. To this end, contact is made with various stakeholders such as the LKN, the Wadden Sea Protection Station, the Jordsand e.V. association and local fishermen. The strandings that occur during the course of the project are also recorded.
2. genetic studies: Samples from dead and live stranded turtles will be genetically analyzed to determine the species and subpopulation.
3. dead body monitoring: Dead stranded sea turtles will be pathologically examined at the ITAW to obtain information on morphometrics, age, sex and disease incidence. In addition to recording biometric data, a macroscopic examination of the carcass is carried out. Depending on the state of preservation of the carcass and the presence of signs of disease, further examinations are carried out. These include histology, parasitology and microbiology.
4. participation in live strandings: The ITAW supports the country in the event of live strandings. This includes advice, contacting international experts, investigation and sampling.
5. establishment of international contacts: This project also aims to establish contacts with sea turtle experts in Europe and worldwide, firstly to become part of the global turtle network and secondly to be able to obtain expert advice on various topics.

The hepatitis E virus (HEV) is mainly transmitted to humans through meat and meat products from infected animals. The transmission route via the environment through contaminated soil, water and/or (arable) plants has long been discussed. Possible vectors include manure or waste water. Many studies show that a considerable proportion of meat and sausage products as well as many wastewater and even surface water samples can be tested positive for HEV RNA. All these studies are based on RT-PCR testing, i.e. the detection of the HEV genome. In order to carry out a better risk assessment, for example when consuming food, and to be able to identify the spread of the virus and chains of infection more precisely, it is necessary to determine the intactness and thus the infectivity of the virus in such samples. In this project, meat and sausage samples as well as environmental samples in the form of manure and wastewater will be analyzed for the presence of HEV RNA as well as for the infectivity of the virus. For this purpose, a stable and efficient cell culture system has been established in recent years, which has already been successfully used to isolate HEV capable of replication from wild and domestic pig organ samples.

Platelet rich plasma (PRP) not only can be used for transfusion to patients with platelet dysfunction who are at high risk of bleeding but also for local wound healing and to treat various diseases such as arthritis. For the latter, growth factors adhering to platelets are thought to play an important role. Platelet solutions, i.e., PRP or platelets in a physiological buffer, have to be locally administered in therapeutic doses at the treatment side. Platelets have a limited shelf life when stored in solution, which may lead to logistic problems for clinical applications. PRP and platelets in a physiological buffer, can only be stored at relatively high temperatures, i.e., above 20°C, during which platelets gradually lose their therapeutic efficacy. Therefore, development of effective platelet biopreservation techniques that maintain platelet functionality are needed to assure off-the-shelf availability. Cryopreservation can be used to store platelet solutions as frozen aliquots, but this requires a complex cold chain logistics, and use of toxic cryoprotective agents that have to be removed prior to use. Dry preservation using natural non-toxic lyoprotective agents such as trehalose would allow room temperature storage and transport.
