Ozone Disinfection Has Minimal Impacts on Larvae of Three Important Species in Aquaculture

Hatchery managers and aquaculturists love to work with fertilized fish eggs because they provide a handling window in which eggs can be manipulated physically without damage. Thus, fertilized egg shipments are commonplace. However, they also worry about disease, and egg shipments require rigorous disinfection with harsh chemicals. Ozone represents a drug-free alternative, but there have... Read More

Artificial Reef Types Affect Red Snapper Sizes

Alabama has the most extensive artificial reef program in the United States, with 15,000-plus artificial reefs. This may come as a surprise to some, considering the state’s coastline is only 60 miles long. With few natural reefs, the government of Alabama and its residents had to be creative when trying to increase fishing opportunities. Since... Read More

Catch-and-Release Practices Inhibit Refuge—Seeking Behavior in Fish

Catch and release is a common practice in the management and conservation of recreational fisheries. In theory, fish are caught and released with minimal harm, allowing them to survive, spawn, and be captured again. In reality, released fish may suffer from physical injuries as well as behavioral impairments, increasing their risk to predators. Fortunately, in... Read More

A Novel and Efficient Way to Assess Net Pen Impacts

Net pen culture has become widespread, and there is growing concern about impacts to benthic communities below the facilities. Potential impacts are hard to assess because the ideal sites for net pen culture are deep, often have currents or cold temperatures, and have patchy substrates that can’t be grab-sampled. Hamoutene et al. (2015) overcame this... Read More

Whirling Disease is Fortunately Not a Permanent Condition

Whirling disease caused by Myxobolus cerebralis is a scourge for fish culturists and salmonid biologists, and rumors have circulated for decades that its myxospores remain viable for years. Nehring et al. (2015) used a carefully designed time-delay study that exposed susceptible oligochaetes to myxospores and then measured production of actinospores as evidence of myxospore viability.... Read More

AFS Journals Offer Insights into Conservation of Apex Predators

Why You Need Granders in a Blue Marlin Fishery The capture of a marlin greater than 500 kg represents a major life achievement for billfish anglers, and fishers refer to marlin of that size using colloquial descriptors such as “Grander” or “Big Julie” depending on location and species. However, their presence in a fishery is... Read More

Sadly, Lionfish Are More Widespread Than We Thought

The invasion of Caribbean reef systems by lionfish Pterois spp. is well documented, and they are now encountered commonly by anglers and sport divers in many areas. However, a trawl survey conducted by the authors found them to be even more widespread in deep (>30 m) low-relief habitats and abundance increased sharply during 2010–2013. Read More

Lobster Trap Debris in a Marine Sanctuary—More Than You Could Imagine

Every year, commercial fishing traps are lost, abandoned, or discarded, contributing to the ever-increasing amount of marine debris submerged on the seafloor. Although recognized worldwide as a detriment to marine ecosystems, quantitative data on the amount of abandoned, lost, or discarded fishing gear is lacking. This journal review originally appeared in the April 2015 issue of Fisheries... Read More

Predicting Brook Trout Presence at the Local Level, Where It Counts

Journal Summary: Predicting Brook Trout Occurrence in Stream Reaches throughout their Native Range in the Eastern United States Brook Trout Salvelinus fontinalis are a popular sport species, but their conservation status is of great concern because many eastern populations have declined. Brook Trout are a paradox. From a basin perspective, they are still present throughout... Read More
