Candidate Species for Florida Aquaculture: Gulf Killifish, Fundulus grandis
https://edis.ifas.ufl.edu/fa190
Gulf killifish — commonly referred to as topminnows — are a promising species for commercial aquaculture, but there are also limitations and culture system considerations of which producers need to be aware. This publication provides concise information to aid producers in making the most informed decisions possible when considering Gulf killifish aquaculture. (Image: Noel Burkhead via Wikimedia Commons)

Dune Restoration and Enhancement for the Florida Panhandle
http://edis.ifas.ufl.edu/pdffiles/SG/SG15600.pdf

Induction and Establishment of Tetraploid Oyster Breeding Stocks for Triploid Oyster Production
https://edis.ifas.ufl.edu/fa215
Triploid oysters are preferred by farmers because of their fast growth, better meat quality, and year-round harvest. Tetraploids are essential for triploid oyster aquaculture because commercial production of all-triploid seed requires sperm from tetraploids. This mini-review focuses on tetraploid oyster production and is a follow-up to a previous publication on triploid oyster production for aquaculture. (Image: Florida Sea Grant)

Top 5 Frequently Asked Questions About the Deepwater Horizon Oil Spill
http://masgc.org/oilscience/2019-top-5-FAQ.pdf
The Deepwater Horizon oil spill occurred in April 2010, about 50 miles offshore of Louisiana. Nearly 172 million gallons of oil entered the Gulf of Mexico. The five questions answered in this publication were those most frequently asked by people impacted by the spill. (Image: Wolfram Burner)

In the Air and On the Water: Technology Used to Investigate Oil Spills
http://masgc.org/oilscience/oil-science-tech-air-water.pdf
Unmanned surface and aerial vehicles — including saildrones, drifters, drones, blimps, and balloons — are used in detection and monitoring of oil spills. These vehicles complement traditional ship, satellite, and mooring-based data collection techniques to give scientists and responders a better understanding of how oil moves on the ocean’s surface. This publication lists some of the features of these unmanned vehicles and how they can be applied to oil spill research and response. (Image: Anna Hinkeldey)

Birds of a Feather – Coping with Oil
http://masgc.org/oilscience/birds-and-oil.pdf
Oil can have a variety of short- and long-term effects on birds, including damage to plumage, poor health, delayed migration, and death. This publication describes the effects of oil spills on birds, both in the timeframe immediately following a spill and in the long term. (Image: Louisiana GOSEP)

Oysters and Oil Spills
http://masgc.org/oilscience/oysters-oil-spills.pdf
Oysters regularly face challenges such as pollution, changing water temperatures, fluctuations in fresh and salt water, harvesting, and coastal development. This publication looks at the effects oil spills have on oysters. (Image: NOAA)

Identifying Forage Populations of Concern: A New Perspective Based on Predator Recruitment Considerations
https://doi.org/10.1016/j.fishres.2019.105319
This paper determines which forage fish are important as prey to four commercially and recreationally important predatory fish along the Florida Gulf coast. It then checks if there is evidence of declining forage fish populations. It notes an unexpectedly high proportion of forage fish populations show decline, but that almost none of these declines could be caused by fishing. Regardless, these declines may affect the recruitment and abundance of valued predatory fish. (Image: NOAA)

Density-dependence In the Life History of Fishes: When Is A Fish Recruited?
https://doi.org/10.1016/j.fishres.2018.09.024
Recruitment is one of the most important stages of fish life history, but exactly when recruitment starts and ends has been mostly a mystery. This paper provides the first empirically-based guidance for determining an appropriate size at recruitment for fisheries stock assessments. It also provides information relevant to a range of fisheries management issues, including the size at which fish should be stocked and the habitat that should be restored to rebuild populations.

Efficacy of Largemouth Bass Stock Enhancement in Achieving Fishery Management Objectives In Florida
https://doi.org/10.1016/j.fishres.2019.01.010
Stock enhancement is a management strategy used for sustaining and rebuilding largemouth bass fisheries in Florida and throughout their native and introduced range. This paper provides a quantitative assessment that compares efficacy of stocking to traditional management approaches. The study shows that stocking is especially effective at rebuilding populations that have collapsed from drought or bad water quality, but is less useful for increasing trophy catches.

Addressing Challenges Common to Modern Recreational Fisheries with a Buffet-Style Landscape Management Approach
https://doi.org/10.1080/23308249.2019.1619071
Providing diverse fishing experiences that appeal to different types of anglers without creating overly complicated regulations has been a challenge in the management of recreational fisheries. This paper borrows ideas from spatial planning to develop a new approach for managing inland recreational fisheries. It suggests that managers use a limited number of regulations to create a “buffet” of different experiences across the landscape, so that anglers can select and visit the ones that are most appealing to them. The paper shows that taking this regional approach should increase angler satisfaction and fishing effort, with minimal risk of over-harvest.

Catch and Non-catch-related Determinants of Where Anglers Fish: A Review of Three Decades of Site Choice Research in Recreational Fisheries
https://doi.org/10.1080/23308249.2019.1583166
The reasons that people make behavioral choices about where and what to fish determines how anglers are likely to behave when fish populations or fishing regulations change. This paper reviews 114 studies and 189 distinct models of angler behaviors conducted between 1988 and 2017 to understand which attributes influence where people recreationally fish. The paper agrees with previous work that catch rate, catch size, and distance are important factors for anglers, but also points out that facilities at fishing sites may be an overlooked but especially important factor.

Impacts of Habitat Repair On A Spatially Complex Fishery
https://doi.org/10.1016/j.ecss.2019.02.007
Fisheries managers often seek to restore habitat to benefit juvenile life stages that recruit to a fishery. A challenge is identifying areas to restore that will efficiently improve fishery outcomes. This paper presents a model that integrates environmental, biological and fisheries information gleaned from previous studies to suggest areas for restoration. These include zones with ample larval settlement, greatly diminished habitat for juvenile life stages, and close proximity to the main fishery grounds. (Image: Florida Sea Grant)

Auction to Benefit Students and Research
https://www.flseagrant.org/news/2019/10/auction-to-benefit-students-and-research/
Karl Havens was Florida Sea Grant director for 11 years before his untimely passing earlier this spring. A skilled photographer and painter, a selection of his works are being auctioned to benefit the Karl Havens Excellence Endowment. This fund will support students and research in fields that Karl advanced, including limnology, coastal and estuarine water quality, and harmful algal blooms. (Image: Karl Havens, Florida Sea Grant)
