... In the tropical and subtropical wet and dry regions, maintaining natural hydrologic connections between coastal rivers and adjacent ephemeral wetlands is critical to conserving and sustaining high levels of fisheries production within these systems. Though there is a consensus that there is a need to maintain these natural connections, little is known about what attributes of floodplain inundation ...
Gambusia holbrooki; Micropterus salmoides; biotic factors; colonizing ability; correlation; fish culture; habitats; indigenous species; ornamental fish; species diversity; temperature; Florida
Abstract:
... Explaining the varying success of invaders is a central question in invasion biology. Florida is a good region to test hypotheses related to invasion because of variation in invasion success where a few non-native fishes have established and spread and some have locally established, whereas many have failed to establish despite high propagule pressure. We sampled fish and habitat near ornamental f ...
... Customers of finfish in China place a high priority on healthy fish at the point of sale but factors that increase the risk of morbidity and mortality during transportation have had limited study. We designed a case study to investigate variation of mortalities claimed by customers receiving fish at markets with above-normal mortalities. We used daily transaction records of the 3 species transport ...

Abstract:
... A whole-lake acoustic telemetry array was utilized to monitor the three-dimensional position of 20 largemouth bass (Micropterus salmoides). Code division multiple access (CDMA) technology enabled the simultaneous monitoring of the 20 transmitters (equipped with pressure and temperature sensors) at 15 s intervals with sub-meter accuracy. Fish were monitored between November 2003 and April 2004 to e ...
... The role of climate variability in the ecology of freshwater fishes is of increasing interest. However, there are relatively few tools available for examining how freshwater fish populations respond to climate variations. Here, I apply tree-ring techniques to incremental growth patterns in largemouth bass (Micropterus salmoides Lacepède) otoliths to explore relationships between annual bass growth ...
Micropterus salmoides; correlation; feeds; fingerlings; grower diets; photoperiod; protein energy ratio; satiety; tanks; water temperature
Abstract:
... We compared performance (growth, survival, condition, and health indices) of largemouth bass, Micropterus salmoides, fingerlings (10.3 g [SE ± 0.5 g] and 92 mm [SE ± 1 mm] total length) fed one of four commercial grower feeds: Purina Aquamax Grower 400 (PAG; PMI Nutrition International LLC), Bio-Oregon BioDiet Grower (BDG; Bio-Oregon), Silver Cup Steelhead (SCS; Silver Cup), and Richloam Bass Fry ...
... The concentration of mercury (Hg) and methylmercury (MeHg) was determined for largemouth bass (Micropterus salmoides), bluegill (Lepomis macrochirus) and black crappie (Pomoxis nigromaculatus) from Maryland reservoirs. Overall, there was a large difference in normalized bass MeHg concentration (for fish of ∼370 mm) between the reservoirs, ranging from <100 ng g⁻¹ to almost 800 ng g⁻¹. Furthermore, ...
Micropterus salmoides; alkalinity; bioaccumulation; body condition; body weight; correlation; ecosystems; environmental factors; fish; marshes; mercury; monitoring; national parks; pH; water conservation; water quality; Florida
Abstract:
... This study evaluates factors, particularly water quality related, that may influence mercury (Hg) bioaccumulation in largemouth bass (LMB, Micropterus salmoides Lacépède) within the Everglades marshes of South Florida. The investigation is an empirical analysis of ambient data from both long-term fish monitoring and marsh water quality monitoring sites across the Everglades Protection Area. Previo ...
... Within areas of comparable atmospheric mercury deposition rates methylmercury burden in largemouth bass populations vary significantly between regulated and unregulated rivers. To investigate if trophic dynamics strongly influenced pollutant body load, we sampled largemouth bass from two adjacent rivers, one regulated and one unregulated, and applied a suite of biochemical and stable isotope assay ...
... Mercury (Hg) trophic transfer and bioaccumulation in fish from a mine‐impacted, eutrophic lake were examined in relation to foraging habitat, trophic position, and size. Diet analysis indicated that there were clear ontogenetic shifts in foraging habitats and trophic position. Pelagic diet decreased and benthic diet increased with increasing fish length in bluegill, black crappie, inland silversid ...
Micropterus salmoides; condition factor; correlation; feeds; fingerlings; food availability; photoperiod; protein composition; protein energy ratio; starter cultures; starter diets; stocking rate; tanks; water temperature; weaning
Abstract:
... We compared performance (growth, survival, and condition) of northern largemouth bass Micropterus salmoides salmoides fingerlings fed one of three commercial starter feeds: Otohime Marine Weaning (OMW; Marubeni Nisshin Feed), Bio-Oregon BiVita Fry (BVF; Bio-Oregon), and Purina Aquamax Starter (PAS; PMI Nutrition International LLC). Nine 833-L circular tanks, connected in parallel to a recirculatio ...
Lepomis; Micropterus salmoides; bass; correlation; game fish; lakes; males; nesting; nests; predation; predators; progeny; sport fishing; spring; swimming; Ontario; Quebec
Abstract:
... Largemouth Bass (Micropterus salmoides) is a highly popular and widely exploited sport fish that provides paternal care to its offspring during the reproductive season each spring. During a catch-and-release angling event, brood predators (e.g. genera Lepomis and Ambloplites) can enter Largemouth Bass nests and consume embryos, reducing the parental male’s reproductive success. While the negative ...
Micropterus salmoides; air temperature; altitude; correlation; endangered species; fish; human population; introduced species; land use; linear models; rain; species diversity; watersheds; Japan
Abstract:
... We analyzed the patterns of total, endangered and exotic fish species richness in 80 reservoirs throughout Japan using Generalized Linear Models (GLMs) with variables of dam characteristics (e.g. reservoir size, isolated period, altitude, DO, pH, rainfall, and air temperature) and watershed characteristics (e.g. watershed area, human population, and land-use patterns). Exotic species richness was ...
... Lakeshore residential development (LRD) reduces coarse woody habitat (CWH) in lakes resulting in negative effects on fishes. We tested whether the addition of CWH could reverse those effects. We added CWH to Camp Lake, a lake with CWH abundances similar to developed lakes, following 2Â years of study of the fish populations in the reference and treatment basins. Both basins were monitored for 4Â y ...
