NBR FIRST EDITION UPDATE TABLE 4.1 SOUTHEAST REGION FISH BYCATCH BY FISHERY Bycatch estimates are in live pounds or number of individuals, except where indicated, and reflect the average from the years identified. Fishery bycatch ratio = bycatch / (bycatch + landings). Some bycatch ratios (marked **) could not be developed, e.g., where bycatch was by weight and numbers of individuals, and landings were in pounds.

Growth and Mortality of Lagodon Rhomboides (Pisces: Sparidae)
GROWTH AND MORTALITY OF LAGODON RHOMBOIDES (PISCES: SPARIDAE) IN A TROPICAL COASTAL LAGOON IN NORTHWESTERN YUCATAN, MEXICO CRECIMIENTO Y MORTALIDAD DE LAGODON RHOMBOIDES (PISCES: SPARIDAE) EN UNA LAGUNA TROPICAL COSTERA EN EL NOROESTE DE YUCATÁN, MÉXICO José Luis Bonilla-Gómez1*, Jorge A. López-Rocha2, Maribel Badillo Alemán2, Juani Tzeek Tuz2 and Xavier Chiappa-Carrara2 ABSTRACT Growth and mortality were estimated for the Lagodon rhomboides pinfish inhabiting La Carbonera, a tropical coastal lagoon on the northwestern coast of the Yucatan Peninsula, Mexico. A total of 448 juvenile and adult individuals were collected monthly between April 2009 and May 2010. The length-weight relationship was calculated and the monthly variation in the condition factor was analyzed. Growth was estimated through the von Bertalanffy growth equation using a length frequency analysis. In addition, mortality was estimated and analyzed. Results showed that fish caught were between 2.1 and 20.0 cm long with an average length of 9.42 cm. The length-weight relationship showed isometric growth. The von Bertalanffy growth model parameters -1 were: L∞ = 21.0 cm, W∞ = 163.46 g, k = 1.1 year and t0 = - 0.158 years. Instantaneous mortality rates were 2.11 and 2.61 year-1 as estimated by the method used. According to the results, growth estimates of L. rhomboi- des along the northwestern coast of Yucatan are higher than those found in the population studied in Florida, suggesting a strong influence of environmental conditions in the growth pattern of this species. This study provides the first growth and mortality estimates forL. rhomboides in the Yucatan Peninsula, which is relevant for the proper implementation of conservation measures for this species. -

Hábitos alimenticios del pez Lagodon rhomboides (Perciformes: Sparidae) en la laguna costera de Chelem, Yucatán, México Walter Gabriel Canto-Maza & María Eugenia Vega-Cendejas Laboratorio de Taxonomía y Ecología de Peces, CINVESTAV-IPN, Unidad Mérida, km 6 antigua carretera a Progreso. AP 73 Cordemex. 97310 Mérida, Yucatán; México; [email protected] Received 13-VIII-2007. Corrected 30-VI-2008. Accepted 31-VII-2008. Abstract: Feeding habits of the fish Lagodon rhomboides (Perciformes: Sparidae) at the coastal lagoon of Chelem, Yucatán, México. Stomach contents of Lagodon rhomboides, the most abundant fish species from seagrass beds in Chelem Lagoon, Yucatan, Mexico, were analyzed. The specimens were collected using a beach seine at eight stations distributed randomly in the lagoon during July, September and November 2002. The trophic components were analyzed by means of the relative abundance (%A) and frequency of occurrence (FO) indices. The trophic similarity between different ontogenetic stages was determined using the Bray-Curtis Index. A total of 90 stomach contents were analyzed. This species is omnivorous, including vegetal and animal material and has a wide trophic spectrum with 58 alimentary items. Trophic ontogenetic variation was significant with a transition from one feeding stage to the next. Small individuals (4.0 -8.0 cm LE) preferentially consume plankton preys and microcrustaceans, while in bigger sizes, the macrocrustaceans, annelids and macrophytes were the main food. Rev. Biol.

A Comparison of Blood Gases, Biochemistry, and Hematology to Ecomorphology in a Health Assessment of Pinfish (Lagodon Rhomboides)
A comparison of blood gases, biochemistry, and hematology to ecomorphology in a health assessment of pinfish (Lagodon rhomboides) Sara Collins1, Alex Dornburg2, Joseph M. Flores2, Daniel S. Dombrowski3 and Gregory A. Lewbart4 1 College of Veterinary Medicine, University of Georgia, Athens, GA, United States 2 Research and Collections, North Carolina Museum of Natural Sciences, Raleigh, NC, United States 3 Veterinary Services Unit, North Carolina Museum of Natural Sciences, Raleigh, NC, United States 4 Clinical Sciences, North Carolina State University College of Veterinary Medicine, Raleigh, NC, United States ABSTRACT Despite the promise of hematological parameters and blood chemistry in monitoring the health of marine fishes, baseline data is often lacking for small fishes that comprise central roles in marine food webs. This study establishes blood chemistry and hematological baseline parameters for the pinfish Lagodon rhomboides, a small marine teleost that is among the most dominant members of near-shore estuarine communities of the Atlantic Ocean and Gulf of Mexico. Given their prominence, pinfishes are an ideal candidate species to use as a model for monitoring changes across a wide range of near-shore marine communities. However, pinfishes exhibit substantial morphological differences associated with a preference for feeding in primarily sea- grass or sand dominated habitats, suggesting that differences in the foraging ecology of individuals could confound health assessments. Here we collect baseline data on the blood physiology of pinfish while assessing the relationship between blood parameters and measured aspects of feeding morphology using data collected from 37 individual fish. Our findings provide new baseline health data for this important near shore Submitted 19 February 2016 fish species and find no evidence for a strong linkage between blood physiology and Accepted 26 June 2016 either sex or measured aspects of feeding morphology. -
