An immune system more complex than thought! Proud to share the discovery of a lymphoid organ in the branchial cavity of zebrafish that is reminiscent of mammalian tonsils in @ScienceAdvances #ScienceAdvancesResearch

[News from Science @NewsfromScience]

Researchers have uncovered a tonsil-like organ in fish that may take on a similar immune role. https://t.co/UWWMGCTOwe

This work has been achieved with precious collaborators @DrSalinasLab @GeertWiegertjes @oehlerslab Mai Nguyen-Chi, Jens Wohlmann, Dimitri Rigaudeau, Finn-Eirik Johansen, Shuo-Wang Qiao, Erling Koppang, Bernard Verrier, Pierre Boudinot, and Gareth Griffiths

@A_Blasweiler Great work Annemiek!

[Annemiek Blasweiler @A_Blasweiler]

Excited to share our new publication at Genomics (special issue: Genomics in Aquaculture 🐟 ). In this paper we evaluate the functional contributions of the two subgenomes of allotetraploid common carp. A special thanks to all co-authors.

Last night we landed in Lombok and now we're at the National Research and Innovation (BRIN) to co-host the symposium on aquaculture and fisheries: connecting Dutch and Indonesian expertise in aquatic research and industry #education #collaboration @brin_indonesia

[Aquaculture & Fisheries - WUR @AFI_WUR]

Indonesia is the 2nd largest producer of marine products in the world. Aruna supports local fishermen educating them on sustainable fishing practices while buying their fish and exporting it locally and to multiple international markets #education #international @arunaindonesia

The final talk of the day! Eleanor Greenway and Timo Stauedle presented research on skate biology with fisheries management. The aim is to bridge knowledge gaps of these data limited species and improve fisheries management #fisheries #skatesandrays @eleanorgreenway @sithitb

[Aquaculture & Fisheries - WUR @AFI_WUR]

Julie Ekasari gave a talk concerning biofloc-based tilapia production. Biofloc encourages healthy aquaculture systems and acts a more efficient food source compared to other feed. This makes the system more productive and improves sustainability #fishfeed #production @sithitb

[Aquaculture & Fisheries - WUR @AFI_WUR]

An interesting talk from Magdalena Lenny Situmorang discussing modulation of bacterial communities in shrimp through feed supplementation. This research looks into different supplements to control bacterial growth and promote fish health #fishhealth #supplements @sithitb

[Aquaculture & Fisheries - WUR @AFI_WUR]

Haniswita and Geert Wiegertjes present their research on trained immunity in fish. By exposing animals to a stimulus they 'train' the innate immune system. After training, immune cells have a higher metabolism and a more effective immune response. #immunity #adaptation @sithitb

[Aquaculture & Fisheries - WUR @AFI_WUR]

Tom Brandon presents research on a novel model for fish intestinal health. Organoids are microscopic organs and can replace animal experiments. He uses carp intestinal organoids to study underlying mechanisms of immune system responses to stimuli #immunity #organiods @sithitb

[Aquaculture & Fisheries - WUR @AFI_WUR]

An interesting and important talk from Dr. Angga Dwiartama on food waste and the value chain in the aquaculture sector. By addressing questions concerning the complexity of the value chain we need to discuss making aquaculture more sustainable #foodwaste #sutainable @sithitb

[Aquaculture & Fisheries - WUR @AFI_WUR]

Kicking off the joint seminar with AFI and the Bandung Institute of Science and Technology discussing Sustainable Aquatic Systems! Follow the link to join us online! #networking #research @sithitb

Teddy Pieter discussed how to build sustainable aquaculture with genetically modified shrimp. These shrimp have increased growth and better tolerances to the environment. Genetics informs sustainable breeding for higher productivity with fewer resources @sithitb @hendrixgenetics

[Eleanor Greenway @EleanorGreenway]

Earlier this week we arrived in Indonesia for the PhD knowledge exchange. It's been amazing so far and today I'm presenting with Timo our research Bogor Institute of Science and Technology @sithitb click the link to join! Our talk will be at 09:30/10:30 (ENG/NL time)¾

[Aquaculture & Fisheries - WUR @AFI_WUR]

Day 3 - Part One. Some really engaging talks while we were visiting the Bandung Institute of Science and Technology (ITB). Our focus here was to promote collaborations between WUR and ITB and encourage future student exchanges during their studies #exchange #networking @sithitb

[Aquaculture & Fisheries - WUR @AFI_WUR]

Day 3: Part 2 Entrepreneurs from eFishery developed new and improved feeding technologies that enables farmers to work more efficiently. eFishery collaborates with multiple stakeholders to aggregate data and refine management techniques #innovation @efishery_ai @gibranhuzaifah

[Aquaculture & Fisheries - WUR @AFI_WUR]

Day 2. A great day at the Bogor Agricultural University (IPB). We got the opportunity to see their aquaculture ponds which are used to investigate a variety of research questions concerning farmed fish species #Aquaculture #fish #research #IPB

[Aquaculture & Fisheries - WUR @AFI_WUR]

Day 1 of the AFI Exchange. Today we visited the Agricultural and Fish Food company 'De Heus'. This company focuses on responsible and sustainable practices for livestock and fish food production #deheus #sustainablefishfeed #collaboration #wur
