BISMARCK — North Dakota Game and Fish fisheries biologists spend a lot of time in fall surveying district lakes and the Missouri River System in North Dakota looking for natural fish reproduction, ...

Some species of fish can evolve their egg-laying habits in response to predators in the area in order to survive, according to new research. Some species of fish can evolve their egg-laying habits in ...

Every year in September and October, fisheries biologists for the North Dakota Game and Fish Department conduct fall fish reproduction surveys on lakes and rivers in North Dakota. Game and Fish ...

Fish reproductive biology and ecology encompass a diverse range of phenomena from gametogenesis and spawning strategies to larval development and recruitment patterns. Recent studies have highlighted ...

The kisspeptin system is increasingly recognised as a central regulator of reproductive physiology in fish. Unlike mammals, teleosts often harbour two or more kisspeptin genes (e.g. Kiss1 and Kiss2) ...

In this segment of “North Dakota Outdoors,” host Mike Anderson takes us to Lake Sakakawea during this year’s fall fish reproduction survey. Fisheries supervisor Russ Kinzler says this year’s fall fish ...

Deep sea anglerfish live in one of the most extreme environments on Earth, where sunlight never reaches and survival depends on extraordinary adaptations. Their bioluminescent lure, powered by ...

Polar fish experience lower mortality than tropical fish, allowing them to delay reproduction until later in life when they are larger and can produce more eggs, according to a study by Mariana ...

In mosquitofish, of the genus Gambusia, male fish are smaller than females -- sometimes only half the size. Biologists had previously assumed that smaller male mosquitofish had at least some ...

The Tibetan Plateau has the richest water resources in Asia, but is highly affected by global climate change. Intensified water cycling has increasingly affected the aquatic environment since the ...

Ranging in size from about 2 to 6 inches, the killifish are ideal for evolutionary studies because they are highly adaptable to their surroundings. Some types of killifish are even known to be ...
