Reproduction and embryonic development of monkeyface prickleback Cebidichthys violaceus in captivity

Journal of Fish Biology, EarlyView.
Abstract Understanding the sequence of embryonic and larval development and the factors necessary to induce reproduction in captivity are critical for developing new species for commercial or conservation aquaculture. In this study, we describe the adult reproductive behaviours and development of eggs, embryos and early larvae of captive monkeyface ...

Studies on Egg Quality : I : Introductory Note on Variations in Yolk Color

Poultry Science, 1926
Abstract That yolks vary in color has been known for a long time but the causes of these variations have received little consideration. Recently however they have assumed commercial importance, since during the last few years a premium has been paid in the New York market for eggs with pale yolks, their color being judged by their shadow when candled.

Aerobic scope is sustained through a heatwave in juvenile Atlantic salmon (Salmo salar)

Journal of Fish Biology, EarlyView.
Abstract Aquatic ectotherms are vulnerable to heatwave‐induced physiological stress, which arises from increased energy demands and reduced dissolved oxygen content in warmer waters. Understanding thermal physiology is critical for predicting how commercially and ecologically important populations could be affected by the increasing risk of rising ...

Yolk Color, Candled Egg Grade and Xanthophyll Availability From Dietary Natural Pigmenting Ingredients ,

Poultry Science, 1975
Abstract Pigment-depleted caged egg-type hens were fed 5, 10, 15 and 20 mg. of xanthophyll per kg. of feed; the xanthophyll levels were obtained from various combinations of white corn, yellow corn, alfalfa meal and corn gluten meal. Beta-apo-8′-carotenal, at the same dietary levels, was used as a standard. Eggs were collected at weekly intervals for

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)

Journal 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).
