Accidental Breakthrough: An Unexpected Laboratory Hybrid of a Critically Endangered Fish Species

Sometimes scientific breakthroughs happen by sheer accident. That was certainly the case with scientists studying the Russian sturgeon. An unexpectedly successful cross-species breeding experiment resulted in the first documented surviving hybrids of Russian sturgeon and American paddlefish. This opens new doors and frontiers for fish genetics, aquaculture, and potential survival strategies for critically endangered sturgeon species.

Bugmeal: The Future of Aquaculture?

With global declines in wild fish stocks, there is an increasing demand for fish grown through aquaculture. Yet current diets for aquaculture fish are mostly made of fish sourced from wild fisheries and from the aquaculture industry itself (Péron et al., 2010), contributing to unsustainable practices in the industry. In an effort to find a more sustainable replacement, researchers at the Japan International Research Center for Agricultural Sciences conducted a study looking at the effects of substituting fish protein used in fish diets with protein made from the younger stages of the black soldier fly. The results look promising.

The Future of Seafood: Integrated Multitrophic Aquaculture

Aquaculture has long been revered as a benefit to the seafood industry by increasing food availability for developing nations and taking pressure off of overexploited wild fish stocks. However, aquaculture has also been cited for its negative environmental impacts. Integrated Multitrophic Aquaculture (IMTA) is a solution that combines species of different trophic levels to be grown together in the same aquaculture setting, reducing environmental impacts and increasing overall production.

Tiny Doctors: Cleaner Shrimp Heal Wounds and Aid in Sustainable Fish Production

Throw out the antibiotics and bring in the shrimp! In a recent study, researchers at the Center for Sustainable Tropical Fisheries and Aquaculture found cleaner shrimp to be an effective biologic control in preventing parasitic infestations in farm-raised fish.

Can seaweed farming help fight climate change?

Seaweed farming is the fastest growing sector of food production and provides healthy, nutritious sea vegetables. Farming seaweed can also have positive benefits by decreasing wave action, taking up carbon dioxide, and locally reducing the effects of ocean acidification. Spatial planning, market analyses, and infrastructure development are needed to facilitate the expansion of seaweed aquaculture.
