Both sexes presented a paired reproductive tract with both sides active and asymmetric gonad development. Microscopic and macroscopic observations of the testes were consistent and indicated seasonality of spermatogenesis. The spermatocyst de - velopment pattern in mature individuals could not be assigned to any of the categories described in the literature. The ovaries−epigonal organ association was of the external type. Although all Squatinidae share a conservative morphology, they show differences across species in the func- tionality of the paired reproductive tract, seasonality of spermatogenesis, coiled spermatozoa and the presence of egg candles. -

(†) Deceased SUMMARY: The southern Brazilian coast is the major fishery ground for the Brazilian sardine (Sardinella brasiliensis), a species responsible for up to 40% of marine fish catches in the region. Fish spawning and recruitment are locally influenced by seasonal advection of nutrient-rich waters from both inshore and offshore sources. Plankton communities are otherwise controlled by regenerative processes related to the oligotrophic nature of the Tropical Water from the Brazil Current. As recorded in other continental margins, zooplankton species diversity increases towards outer shelf and open ocean waters. Peaks of zooplankton biomass and ichthyoplankton abundance are frequent on the inner shelf, either at upwelling sites or off large estuarine systems. However, meandering features of the Brazil Current provide an additional mechanism of upward motion of the cold and nutrient-rich South Atlantic Central Water, increasing phyto- and zooplankton biomass and produc- tion on mid- and outer shelves. Cold neritic waters originating off Argentina, and subtropical waters from the Subtropical Convergence exert a strong seasonal influence on zooplankton and ichthyoplankton distribution towards more southern areas. -
Comparison of an Active and a Passive Age-0 Fish Sampling Gear in a Tropical Reservoir
Comparison of an Active and a Passive Age-0 Fish Sampling Gear in a Tropical Reservoir M. Clint Lloyd, Department of Wildlife, Fisheries and Aquaculture, Mississippi State University, Box 9690 Mississippi State, MS 39762 J. Wesley Neal, Department of Wildlife, Fisheries and Aquaculture, Mississippi State University, Box 9690 Mississippi State, MS 39762 Abstract: Age-0 fish sampling is an important tool for predicting recruitment success and year-class strength of cohorts in fish populations. In Puerto Rico, limited research has been conducted on age-0 fish sampling with no studies addressing reservoir systems. In this study, we compared the efficacy of passively-fished light traps and actively-fished push nets for sampling the limnetic age-0 fish community in a tropical reservoir. Diversity of catch between push nets and light traps were similar, although species composition of catches differed between gears (pseudo-F = 32.21, df =1,23, P < 0.001) and among seasons (pseudo-F = 4.29, df = 3,23, P < 0.006). Push-net catches were dominated by threadfin shad (Dorosoma petenense), comprising 94.2% of total catch. Conversely, light traps collected primarily channel catfish Ictalurus( punctatus; 76.8%), with threadfin shad comprising only 13.8% of the sample. Light-trap catches had less species diversity and evenness compared to push nets, consequently their efficiency may be limited to presence/ absence of species. These two gears sampled different components of the age-0 fish community and therefore, gear selection should be based on- re search goals, with push nets an ideal gear for threadfin shad age-0 fish sampling, and light traps more appropriate for community sampling. -

The Zebrafish Anatomy and Stage Ontologies: Representing the Anatomy and Development of Danio Rerio
Van Slyke et al. Journal of Biomedical Semantics 2014, 5:12 http://www.jbiomedsem.com/content/5/1/12 JOURNAL OF BIOMEDICAL SEMANTICS RESEARCH Open Access The zebrafish anatomy and stage ontologies: representing the anatomy and development of Danio rerio Ceri E Van Slyke1*†, Yvonne M Bradford1*†, Monte Westerfield1,2 and Melissa A Haendel3 Abstract Background: The Zebrafish Anatomy Ontology (ZFA) is an OBO Foundry ontology that is used in conjunction with the Zebrafish Stage Ontology (ZFS) to describe the gross and cellular anatomy and development of the zebrafish, Danio rerio, from single cell zygote to adult. The zebrafish model organism database (ZFIN) uses the ZFA and ZFS to annotate phenotype and gene expression data from the primary literature and from contributed data sets. Results: The ZFA models anatomy and development with a subclass hierarchy, a partonomy, and a developmental hierarchy and with relationships to the ZFS that define the stages during which each anatomical entity exists. The ZFA and ZFS are developed utilizing OBO Foundry principles to ensure orthogonality, accessibility, and interoperability. The ZFA has 2860 classes representing a diversity of anatomical structures from different anatomical systems and from different stages of development. Conclusions: The ZFA describes zebrafish anatomy and development semantically for the purposes of annotating gene expression and anatomical phenotypes. The ontology and the data have been used by other resources to perform cross-species queries of gene expression and phenotype data, providing insights into genetic relationships, morphological evolution, and models of human disease.

This loss of lateral line canal segments 16 is frequently accompanied by proliferation of superficial neuromasts. Although the proliferation 17 of superficial neuromasts forms intricate patterns that have been used as a taxonomic tool to 18 identify individual gobiid species, there has never been a detailed study that has documented the 19 development of the lateral line system in gobies. The Round Goby, Neogobius melanostomus, is 20 the focus of this study because the absence of the lateral line canal segments below the eye are 21 accompanied by numerous transverse rows of superficial neuromasts. -

Early developmental stages and ecotone utilisation of the non-indigenous Round Goby, Neogobius melanostomus (Pallas, 1811), are described and illustrated. Fish (5-40 mm) were collected in coarse gravel, rocks and debris in the St. Clair River/Lake system, Ontario, in 1994-2000. The Round Goby hatches at about 5 mm with black eyes, flexed urostyle, and developed fins and digestive system. Distinguishing characters include large head, dorsolateral eyes, large fan-shaped pectoral fins, two dorsal fins, fused thoracic pelvic fins and a distinct black spot on the posterior of the spinous dorsal fin. Modal counts for preanal, postanal, and total myomeres were 12, 19, and 31, respectively.

Estimating Spawning Times of Alligator Gar (Atractosteus Spatula) in Lake Texoma, Oklahoma
46 Estimating Spawning Times of Alligator Gar (Atractosteus spatula) in Lake Texoma, Oklahoma Richard A. Snow Oklahoma Department of Wildlife Conservation, Oklahoma Fishery Research Laboratory, Norman, OK 73072 James M. Long U.S. Geological Survey Oklahoma Cooperative Fish and Wildlife Research Unit, Department of Natural Resource Ecology and Management, Oklahoma State University, Stillwater, OK 74078 Abstract: In 2013, juvenile Alligator Gar were sampled in the reservoir-river interface of the Red River arm of Lake Texoma. The Red River, which flows 860 km along Oklahoma’s border with Texas, is the primary in-flow source of Lake Texoma, and is impounded by Denison Dam. Mini- fyke nets were deployed using an adaptive random cluster sampling design, which has been used to effectively sample rare species. Lapilli otoliths (one of the three pair of ear stones found within the inner ear of fish) were removed from juvenile Alligator Gar collected in July of 2013. Daily ages were estimated by counting the number of rings present, and spawn dates were back-calculated from date of capture and subtracting 8 days (3 days from spawn to hatch and 5 days from hatch to swim- up when the first ring forms). Alligator Gar daily age estimation ranged from 50 to 63 days old since swim-up. Spawn dates corresponded to rising pool elevations of Lake Texoma and water pulses of tributaries. ©2015 Oklahoma Academy of Science Introduction In its native range, Alligator Gar spawns from early April through the middle of June The Alligator Gar (Atractosteus spatula) is in conjunction with seasonal flooding events the largest freshwater fish species in Oklahoma (Etnier and Starnes 1993, Ferrara 2001, Inebnit and the third largest in North America (Page and 2009). -
Family Lepisosteidae (Gars)
Invasive Species Fact Sheet Gar, Family Lepisosteidae General Description Gars are large, freshwater fish belonging to the Lepisosteidae family, which consists of 7 species of gar: alligator, Cuban, Florida, longnose, shortnose, spotted, and tropical. Gars have long, cylindrical bodies covered in hard, shiny, diamond-shaped Alligator gar (Atractosteus spatula) scales. Their dorsal and anal fins sit far back on the body, Photo by South Carolina Department of Natural Resources near the tail. They have slender snouts with sharp, needle- like teeth. Gars are generally green to brown in color on their top and sides and white to yellow on their bellies; some species have spots on their bodies and/or fins. The different species of gar can be distinguished by snout length, number of rows of teeth, and the amount and location of spots. Depending on the species, adult gar range from 1 to over 9 feet long. The largest species of gar, the alligator gar, has been reported to grow up to 10 feet and weigh 350 lbs. Current Distribution Gars are not currently found in California. Alligator gars have been collected in California waters on a few occasions, but these fish were likely the result of aquarium releases. Five of the seven gar species are native to the United States. Spotted gars (Lepisosteus oculatus) confiscated Gars are currently found within and outside of their native ranges in by CDFW wardens the United States from the Great Lakes basin in the north, south Photo by CDFW through the Mississippi River drainage to Texas, Mexico, and Florida. Florida gars are only found in Florida and Georgia. -

While international focus has been on the effects of noise on marine mammals, Norway has managed seismic surveys based on the potential impact on fish stocks and fisheries since the late 1980s. Norway is, therefore, one of very few countries that took fish into account at this early stage. Until 1996, spawning grounds and spawning migration, as well as areas with drifting eggs and larvae were recommended as closed for seismic surveys. Later results showed that the effects of seismic surveys on early fish development stages were negligible at the population level, resulting in the opening of areas with drifting eggs and larvae for seismic surveys. Spawning grounds, as well as concentrated migration towards these, are still closed to seismic surveys, but the refinement of areas and periods have improved over the years. Since 2018, marine Citation: Sivle, L.D.; Vereide, E.H.; mammals have been included in the advice to management.
