Mariculture: significant and expanding cause of coastal nutrient enrichment
Environmental Research Letters, 2013 Mariculture (marine aquaculture) generates nutrient waste either through the excretion by the reared organisms, or through direct enrichment by, or remineralization of, externally applied feed inputs.

Hox Gene Variation Drives Morphological Specialization of Humpback Grouper Cromileptes altivelis
Integrative Zoology, EarlyView.Cromileptes altivelis exhibits a distinctive “sunken head and humpback” morphology, formed through cranial remodeling. Genetic analyses identified unique amino acid variants in Hoxa7a and Hoxa10b, with functional tests confirming their role in enhancing osteoblast activity and driving cranial remodeling.

Evaluation of greenhouse gas emissions and design of mitigation options: A whole farm approach based on farm management data and mechanistic models [PDF]
, 2008 Agricultural activities are important sources of atmospheric nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2). In the European Union, the agricultural sector contributes approximately 10% of the total emitted greenhouse gases (GhG). We search

Using Eye Lens Stable Isotopes to Identify the Rearing Origin of Fall Age‐0 Walleye (Sander vitreus)
Fisheries Management and Ecology, EarlyView.ABSTRACT Isotope values in fish eye lenses may be useful in differentiating rearing origins. We compared eye lens isotopic values of fall fingerling age‐0 walleye (Sander vitreus) reared in a hatchery pond, a recirculating aquaculture system (RAS), and a natural lake. Using 10 fish per rearing source, we delaminated layers from one eye lens per fish to

Journal of Fish Biology, EarlyView.Abstract Anadromous salmonids migrate seaward to exploit feeding and growth opportunities in marine habitats, yet how smolt biological characteristics influence their marine migratory behavior remains poorly understood. This study used 9 years of trout (Salmo trutta) population monitoring data from 15,595 tagged age‐0+ parr, 1033 smolts detected ...

Journal of Fish Biology, EarlyView.Abstract High‐latitude ecosystems are simultaneously warming and acidifying under ongoing climate change. Arctic cod (Boreogadus saida) are a key species in the Arctic Ocean and have demonstrated sensitivity to ocean warming and acidification as adults and embryos, but their larval sensitivity to the combined stressors is unknown. In a laboratory multi‐
