Reproductive behaviour of the ocean triggerfish Canthidermis sufflamen (Tetraodontiformes: Balistidae) in the shallow waters of the marine‐protected area of El Hierro Island (Canary Islands)

open access: yesJournal of Fish Biology, EarlyView.
Abstract The abundance of Canthidermis sufflamen has increased worldwide, including around the Canary Islands, due to global ocean warming. The reproductive behaviour of this species was studied within a marine‐protected area (MPA) and its adjacent areas off the island of El Hierro (Canary Islands).

Ultrasonography as a non‐invasive technique to assess the effects of diet on the ovaries of female European seabass (Dicentrarchus labrax)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Broodstock management in aquaculture aims to optimise larval production to meet farm demand, which requires precise monitoring of the reproductive cycle. Traditional methods such as histology often require killing of fish, making them unsuitable for monitoring reproductive dynamics at fish level.

Effects of Dietary Supplementation of Natural Pigments on Egg Yolk Color in Laying Hens.

open access: yesJapanese poultry science, 1994
産卵開始後約8ヵ月経過した産卵鶏に対して,コーングルテンミール(CM),マリーゴールド花弁粉末(MM),パプリカ粉末(PM)およびパプリカ抽出処理物(PE)の4種類の天然卵黄着色強化剤を20日間投与し,卵黄の着色効果を比較検討した。その結果,すべての着色強化剤は無添加対照区に対して,ロシュのヨークカラーファン値(RCF値)を有意に高め卵黄に対する着色効果を認めた。しかしながら,飼料中のキサントフィルを同量にしたにもかかわらず,RCFは赤色色素に対する感応が強いため,飼料中の黄色系キサントフィルの多いCMとMMは,赤色系キサントフィルを多く含むPMおよびPEよりも,RCF値を高めることはできなかった。色差計によるイエローインデックス(YI)および赤色度(a値)は,RCF値と同じ傾向が見られ ...

Axial muscle‐fibre orientations in larval zebrafish

open access: yesJournal of Anatomy, Volume 246, Issue 4, Page 517-533, April 2025.
In 4 days post‐fertilization zebrafish larvae, the fast axial muscle fibres follow helical trajectories that taper towards the tail. Adjacent muscle fibres form substantial angles relative to each other to accommodate this pattern. Using a novel semi‐automatic method, we quantified 3D fibre angles over the whole muscle volume.

Development of the abdominal musculature in the chicken embryo

open access: yesJournal of Anatomy, EarlyView.
In this study, we investigate anatomy, morphogenesis, segmental origin, and fiber formation of the abdominal musculature in the chicken embryo. We show that abdominal muscles arise from somites 24 to 28, and that the segmental identity of individual fibers in the abdominal muscle sheets is maintained.

3D transparent technology displays the developmental patterns of ductus arteriosus morphology in chicken embryos before and after birth

open access: yesJournal of Anatomy, EarlyView.
At the eighth week of human embryonic development, 3D transparent imaging enables clear visualization of the outflow tract's morphological features, revealing its anatomical components in detail. Abstract The ductus arteriosus (DA) is a critical fetal vascular structure that shunts blood from the pulmonary artery to the aorta, bypassing the non ...
