Highly and Lowly Domesticated Endangered Fish From a Conservation Hatchery Diverge in Their Thermal Physiology, Transcriptome, and Methylome Conservation hatcheries aim to produce fish for supplementation of wild populations, but hatchery environments may drive phenotypic divergence from wild fish. These diverged traits may have reduced f...

Our publication is now available:
“Highly and Lowly Domesticated Endangered Fish… Diverge in Thermal Physiology, Transcriptome, and Methylome.”

Access it here: doi.org/10.1111/eva....

Finally, out today! Morphometric variation and sexual dimorphism of endangered longfin smelt Spirinchus thaleichthys in the San Francisco Estuary. Interested? Find it here: doi.org/10.3354/esr0...

New publication in Fisheries Research: “Retention rate and biological effects of Floy and FRyID tags on juvenile longfin smelt (Spirinchus thaleichthys).”

The findings inform tag selection for small, conservation-focused fish species.

Another collaborative publication for 2026 is out. We link estuarine ecology with reproductive phenology of the Indian backwater oyster Crassostrea madrasensis using a multivariate framework. Interested? doi.org/10.1016/j.se...

Our first publication of 2026 is out. We show how cultivation site and depth shape shell form and color in green mussels (Perna viridis) from the Bay of Bengal using morphometrics and color profiling. Shell traits act as bioindicators and guide better mariculture management.

Thank you so much. Ok, I’ll check it out soon. Happy new year.

Thank you so much, Hobbs. Happy New Year!

Another productive year comes to a close.

After completing three years of my PhD, I had published e...

Our new study shows that Perna viridis synchronizes reproduction with estuarine productivity, with stage-specific fatty acid signatures and n-3 PUFAs as biomarkers, indicating opportunistic post-monsoon reproduction linked to plankton dynamics. doi.org/10.1016/j.ec...

Integrated insight into somato-gonadal fatty acid dynamics and environmental synchrony: Unravelling post-monsoon gametogenic strategies of oysters Crassostrea madrasensis in raft-cultivation systems The Indian backwater oyster, Crassostrea madrasensis, is a keystone estuarine bivalve of ecological and economic importance. Despite its significance,…

Our new study reveals how somatic and gonadal fatty acids are mobilized during post-monsoon reproduction in the oyster Crassostrea madrasensis. Interested? please find it here: www.sciencedirect.com/science/arti...

Our new paper is out: We report how Crassostrea madrasensis adjusts its feeding and reproduction in response to seasonal plankton shifts and environmental changes along the Bay of Bengal. The study offers insights for sustainable bivalve farming in monsoon-driven coasts.

Our collaborative study shows that hatchery domestication in Delta smelt elevates thermal tolerance but reduces plasticity, with transcriptome and methylome shifts influencing adaptation. Read the preprint here: www.biorxiv.org/content/10.1...

As Lab Safety Coordinator, I was hoping to see a publication in this area. Pleased to share our collaborative work “Factors affecting self-reported occupational health-related problems: a case study on improved traditional shrimp farmers in Bangladesh.”

Happy to share that our study is now out today, revealing that a 7-day interval between sperm collections is insufficient for full recovery, resulting in reduced sperm motility—regardless of male age—in the endangered delta smelt. Interested? Find it: doi.org/10.3354/esr0...

🎉 A major milestone!

For the first time, we successfully fertilized and hatched Delta Smelt larvae using cryopreserved sperm.

This breakthrough offers new hope for the spawning success and conservation of this critically endangered species. Interested? Please see the video 😊

New Publication Alert: Ramshorn Snail (Helisoma anceps) shows a preference for consuming non-viable fish eggs over the live ones. Findings highlight its potential use as a natural tool for dead egg removal in endangered Delta Smelt hatchery operations. www.tandfonline.com/doi/full/10....

The final batch of endangered longfin smelt has hatched! Despite challenges in broodstock availability, we have 70,000+ larvae at 40 dph. Excited to track survival and growth performance at 80 & 300 dph with diet & tagging experiments. Huge thanks to our collaborators! #Conservation #Fisheries

Impact of ingested microplastics on phenotypic traits and biochemical parameters in Nile tilapia (Oreochromis niloticus) juvenile - Aquaculture International The widespread contamination of aquatic environments by microplastics (MPs), alongside other pollutants, has emerged as a critical global concern, posing significant risks to fish populations. This st...

🚀 New Publication Alert!

Our study reveals how microplastic ingestion affects survival, growth, and immunity in tilapia.

I contributed to study design, data analysis, and visualization. Thanks to my co-authors and collaborators for their efforts!
