Standardized invasive species terminology for effective education of Floridians

Journal of Extension

Basil V Iannone III, Emily C Bell, Shannon Carnevale, Jeff E Hill, Julie McConnell, Martin Main, Stephen F Enloe, Steven A Johnson, James P Cuda, Shirley M Baker, Michael Andreu

2021 In this publication we introduce a standardized set of seven terms compiled by the members of the UF|IFAS Invasive Species Council that can describe most situations involving invasive species. The goal of this list is to promote a common language among Extension and outreach professionals. This common language will improve invasive species education and limit confusion caused by the excessive jargon used to describe invasive species and the fact that much of this jargon is used incorrectly. This confusion hinders stakeholder understanding of environmental and economic impacts caused by invasive species. Confusion can prevent stakeholders from adopting behaviors that can both limit the introduction of new invasive species and decrease the impacts of those already established.

Development of a rapid colorimetric strip method for determination of volatile bases in mahi-mahi and tuna

Journal of Food Science

Jing Bai, Shirley M Baker, Renee M Goodrich‐Schneider, Naim Montazeri, Paul J Sarnoski

2021 Tuna (Thunnus albacares) and mahi-mahi (Coryphaena hippurus) are two major fish species responsible for scombroid poisoning in the United States. The purpose of this research was to develop a low-cost and easily operated colorimetric strip method for the rapid determination of spoilage degree via amine response in mahi-mahi and tuna. The color strip method was developed by investigating different types of dyes, filter papers, sample volume, water bath temperature, and other parameters. Ultimately rose bengal and bromophenol blue (BPB) dyes were chosen. These two dyes produced standard curves with good linearity (0–50 mg/L for the total biogenic amines) and uniformity of color change. The r2 values for the standard curves of the rose Bengal and BPB were 0.9535 and 0.8883, respectively.

Carbon Mineralization Associated with Aquaculture of the Northern Quahog Mercenaria mercenaria

Journal of Shellfish Research

Patrick Baker, Shirley M Baker

2019 Molluscs mineralize carbon as calcium carbonate in shells within a protein matrix that is a small portion of the total shell mass. In parts of Florida, the northern quahog Mercenaria mercenaria is cultured in mesh bags in shallow coastal marine habitats. These habitats were selected by the State of Florida for their pre-existing lack of large molluscan populations, so most of the shell material harvested by aquaculture operations would not otherwise exist. The carbonate content of shell material was quantified by coulometry, and shell production was estimated per harvested clam, and per unit area per year. The majority of the shell material harvested (about 91%) was M. mercenaria, and the remainder came from other species of molluscs that grew in or on the mesh bags. Of the non-Mercenaria shell material, most (8.5% of total percentage) came from oysters (Crassostrea virginica and Ostrea stentina), and the rest from at least 37 other species of molluscs and other shelled taxa.

Simultaneous Determination of Amino Acids and Biogenic Amines in Tuna and Mahi-Mahi by Reversed-Phase Ultra-High Performance Liquid Chromatography

Journal of Aquatic Food Product Technology

Jing Bai, George L Baker, Shirley M Baker, Renee M Goodrich Schneider, Naim Montazeri, Paul J Sarnoski

2019 Tuna and mahi-mahi are two major fish species responsible for histamine poisoning. This research developed a rapid ultra-high performance liquid chromatography (UHPLC) method to determine amino acids, histamine, and other biogenic amines that can act as co-indicators of histamine poisoning in tuna and mahi-mahi. The modified UHPLC method could simultaneously determine four biogenic amines and 10 major free amino acids in mahi-mahi (Coryphaena hippurus) and yellowfin tuna (Thunnus albacares) within 17.5 min. This UHPLC method showed good linear response, sensitivity, resolution, recovery, repeatability, and number of theoretical plates. The concentrations of detected amino acids, biogenic amines in mahi-mahi and tuna, and their relationships with fish spoilage grade were determined by this UHPLC method. The developed UHPLC method is a rapid and accurate way to monitor quality changes of mahi-mahi and tuna by inspecting the changes of amino acids and biogenic amines.

Aroma Profile Characterization of Mahi-Mahi and Tuna for Determining Spoilage Using Purge and Trap Gas Chromatography-Mass Spectrometry

Journal of Food Science

Jing Bai, Shirley M Baker, Renee M Goodrich‐Schneider, Naim Montazeri, Paul J Sarnoski

2019 Alcohols, aldehydes, ketones, amines, and sulfur compounds are essential aroma compounds related to fish flavor and spoilage. Gas chromatography-mass spectrometry (GC-MS) is an instrument that is widely used to identify and quantify volatile and semi-volatile compounds in fish products. In this research, a simple and accurate GC-MS method was developed to determine the aroma profile of mahi-mahi and tuna for chemical indicators of spoilage. In the developed GC-MS method, trichloroacetic acid (TCA) solution was used to extract analytes from homogenized fish samples. The purge and trap system was used for sample introduction, and the GC-MS with an RTX-Volatile Amine column was able to separate compounds without a derivatization procedure.
