Abstract:
Plasma osmotic and electrolyte concentrations as well as branchial Na+/K+ and Mg++ ATPase activities were determined in the field for largemouth bass, Micropterus salmoides, from a brackish marsh and freshwater lake in southcentral Louisiana. Laboratory experiments were conducted to evaluate plasma chemistry and gill ATPase activities of largemouth bass from both locations exposed to 0, 4, 8, and 12‰ salinity. No significant differences in physiological responses were detected between marsh and freshwater largemouth bass exposed to 0, 4, or 12‰. Exposure to 12‰ salinity resulted in osmotic stress in largemouth bass from both locations. At 8‰, marsh largemouth bass had significantly higher plasma solutes and lower gill ATPase activities than freshwater fish. Different physiological responses by marsh and freshwater largemouth bass during exposure to 8‰ salinity indicated that marsh largemouth bass have adapted to environments of variable salinity by reducing active ion transport and tolerating elevated plasma son levels.

Abstract:
In situ and laboratory feeding trials coupled with stomach content analysis of largemouth bass (Micropterus salmoides) were performed to examine how turbidity influences the size selectivity and capture rates of prey. No significant differences in the capture success of adult largemouth bass preying on northern redbelly dace (Phoxinus eos) were observed during in situ feeding trials in two Lake Ontario coastal wetlands differing in turbidity level (2.3 and 20 nephlometric turbity units (NTU)). During 1-h laboratory feeding trials, the overall number of fathead minnows (Pimephales promelas) captured was not significantly different among 1-, 18-, and 37-NTU treatments. However, at 70 NTU, the number of fathead minnows captured was significantly lower than that at the lowest turbidity treatment. Selection by juvenile largemouth bass of the smallest size-class of fathead minnow decreased as turbidity increased. No significant differences in piscivory were apparent between juvenile largemouth bass collected from turbid and clear habitats. Stomach content comparisons of juvenile largemouth bass seined from six clear and turbid habitats suggest that piscivory is primarily regulated by the availability of vulnerable size-classes of prey fish, as opposed to water clarity.

Abstract:
This study aimed to evaluate classification algorithms to predict largemouth bass (Micropterus salmoides) occurrence in South Korea. Fish monitoring and environmental data (temperature, precipitation, flow rate, water quality, elevation, and slope) were collected from 581 locations throughout four major river basins for 5 years (2011–2015). Initially, 13 classification models built in the caret package were evaluated for predicting largemouth bass occurrence. Based on the accuracy (>0.8) and kappa (>0.5) criteria, the top three classification algorithms (i.e., random forest (rf), C5.0, and conditional inference random forest) were selected to develop ensemble models. However, combining the best individual models did not work better than the best individual model (rf) at predicting the frequency of largemouth bass occurrence. Additionally, annual mean temperature (12.1 °C) and fall mean temperature (13.6 °C) were the most important environmental variables to discriminate the presence and absence of largemouth bass. The evaluation process proposed in this study will be useful to select a prediction model for the prediction of freshwater fish occurrence but will require further study to ensure ecological reliability.

Abstract:
Abstract Largemouth Bass Micropterus salmoides, Florida Bass Micropterus floridanus, and their intergrade are socially and economically valuable sport fish. In the southeastern United States, it is customary for fisheries personnel to age black bass Micropterus species using sagittal otoliths, which requires killing the fish. Presently, fisheries managers and black bass anglers show reluctance to sacrifice large individuals. Development of a nonlethal ageing technique would not only allay concerns of sacrificing large black bass, but it could offer a pathway for new research, management, and conservation. We excised dorsal spines III–V from Largemouth Bass in Florida varying from 30 to 57 cm total length to evaluate the effects of the procedure on survival over 35 d. No mortalities were observed for fish with excised dorsal spines, and experiment-wide survival was 0.94 (0.87–1.00; 95% confidence interval). No significant differences in survival, weight change, or incidence of external injuries were observed between control and excised fish. The areas of spine excision healed with no visible infection or inflammation at the conclusion of the experiment. Therefore, dorsal spine removal offers managers a nonlethal option for collecting ageing structures of adult Largemouth Bass in Florida, including large individuals, and this result likely extends to other Micropterus species as well.

Abstract:
Stocks of northern largemouth bass (NLMB), Micropterus salmoides salmoides, Florida largemouth bass (FLMB), M. s. floridanus, and both reciprocal F1 hybrids were produced through natural spawning; the genetic composition of each stock was confirmed electrophoreticaliy, and experimental populations established. One set of experimental populations (P1 and P2) contained as broodstock equal numbers of adult NLMB and FLMB, whereas the other set (H1 and H2) initially contained equal numbers of adults of both reciprocal F1 hybrids and both pure subspecies. Each year-class produced experimentally were sampled and individuals analyzed genetically to determine their parentage. Initially, much of the YOY production in P1 and P2 was composed of small FLMB that did not survive winter well; once naturally produced F1 hybrids entered the breeding pool, most offspring were Fx hybrids, and the population became heavily introgressed. In H1 and H2 introgression began with the production of the first year-class. Within each year-class NLMB produced in all ponds were significantly larger than all other genotypes, but it appears likely that after only a few generations, production of pure NLMB ceases, all individuals being Fx hybrids. Results illustrate the potential negative impacts of introducing FLMB or hybrids between it and NLMB into waters within or contiguous to the native range of the northern subspecies.

Abstract:
We compared vulnerability among tiger muskellunge (Esox masquinongy × E. lucius) (TM), northern pike (E. lucius) (NP), and muskellunge (E. masquinongy) (M) to predation by largemouth bass (Micropterus salmoides). Equal numbers (about 25/ha) and sizes (either 145, 180, or 205 mm) of each esocid taxa were stocked into three reservoirs (40–89 ha) during 3 yr (five stockings total). Tiger muskellunge were significantly more susceptible to predation ([Formula: see text], range 1–53% mortality) than muskellunge ([Formula: see text], range 2–26%); northern pike were intermediate in susceptibility ([Formula: see text], range 2–35%). Esocid size influenced predation rates for all taxa; losses to predation by largemouth bass decreased from an average of 31% at 145 mm to 2% at 205 mm. Pond experiments (N = 7) provided results similar to reservoirs: TM>NP>M. In laboratory pools with simulated vegetation (N = 106 experiments), susceptibility to predation among esocids did not differ. Dispersal rates by esocids were similar in reservoirs and all taxa preferred vegetated habitats. However, differential habitat selection may partially explain why tiger muskellunge are more vulnerable to largemouth bass predation, as they spent more time in open than vegetated habitats in both pond and pool experiments than either of the parent species. For all taxa, stocking lengths [Formula: see text] in fall will increase survival by reducing predatory losses.

Abstract:
Purpose. Largemouth bass (Micropterus salmoides), a fish species native to freshwaters of North America, is a promising object of aquaculture all over the world. This is evidenced by the fact that this species is currently actively cultivated in aquaculture of more than 50 countries worldwide, on all continents, with the exception of Antarctica and Australia, both for recreational fishing and as a table fish. If we consider the history of breeding and cultivation of the largemouth bass, we can note a tendency to a continuous expansion of the stages of cultivation and transition from polyculture to monoculture. For example, in the first half of the last century, fish farms in the United States raised mainly juveniles of largemouth bass for stocking to natural water bodies, but currently most farms use the full production cycle from fry to marketable fish. In addition, earlier largemouth bass was used in many countries mainly as an additional object of aquaculture (biomeliorator) to increase the production of common carp, but now, thanks to the development of recreational fishing, it is increasingly becoming the main object of aquaculture, which is facilitated by the intensification of cultivation methods. Nowadays, there are many methods of growing largemouth bass, from the simplest, extensive, when fish are raised on natural food supply, to most intensive using flow-through aquaculture systems and off-season spawning. On the territory of Ukraine, it may be effective to use pond aquaculture of largemouth bass, which begins from the production of larvae and fry at fish farms. This stage of fish farming will be discussed in this article. Findings. This article contains brief information on method of natural spawning of largemouth bass, filling ponds with water, selection of broodstock and norms for their stocking to spawning ponds, spawning behavior of fish, peculiarities of caring for larvae and fry, sorting juveniles, as well as minimizing injuries during manipulations with fish. Practical value. Information from this review can be used for development of a new method for production of largemouth bass larvae and fry at warm-water pond farms in Ukraine, taking into account climatic conditions and local specificities of aquaculture. Key words: Largemouth bass, Micropterus salmoides, recreation fishing, sport fishing, pond fish farm, aquaculture, biomeliorator, larvae, fry, polyculture, monoculture, intensification, perspective species.

Abstract:
Environmental and genetic factors influence fish spawning periodicity (i.e., the distribution of spawning events during the breeding season), but their relative contributions have rarely been evaluated. We evaluated the relative contribution of genetic and environmental effects on spawning periodicity by rearing Florida largemouth bass (FLMB, Micropterus salmoides floridanus) from Lake Okeechobee and intergrade largemouth bass (ILMB, Micropterus salmoides salmoides × M. s. floridanus) from Lake Seminole in a similar environment. Fish from each genetic source population were translocated to experimental ponds at an intermediate latitude in Gainesville, Florida, in September 2003. We used estimated ages of offspring as an index of spawning events to compare spawning distributions between brood sources in ponds and related those results to spawning distributions at source populations for 2004. FLMB began spawning earlier than ILMB in all ponds, and FLMB had a longer spawning season than ILMB. Similarly, FLMB at Lake Okeechobee began spawning earlier and had a longer spawning season than ILMB at Lake Seminole. Environmental factors (e.g., temperature effects) influenced spawning periodicity for both FLMB and ILMB, but spawning periodicity was also influenced by genetic composition in ponds because translocated fish reflected characteristics of their source populations. Thus, both environmental factors and genetic composition influenced spawning periodicity.

Abstract:
We examined community impacts of bluegill (Lepomis macrochirus) and largemouth bass (Micropterus salmoides) in a summer experimental pond study of factorial design with four treatment combinations (fishless, bluegill, largemouth bass, and bluegill with largemouth bass). Ceriodaphnia reticulata, Daphnia pulicaria, Chaoborus sp., Volvox sp., anisopteran and zygopteran nymphs, and dissolved oxygen levels were suppressed in the presence of bluegill. Diaptomus sp., Conochiloides sp., Cyclotellas sp., Navicula sp., Oocystis sp., Anabaena sp., Ceratium sp., algal fluorescence, turbidity, 5- to 12.7-μm particles, and total phosphorus and total nitrogen were enhanced in the presence of bluegill. Daphnia pulicaria was enhanced and Cyclotella sp. and Oocystis sp. were suppressed in the presence of largemouth bass. Although the effects of the two fish were not independent, as indicated by significant bluegill × largemouth bass interactions for some plankton taxa, we found little evidence of bluegill impacts being reversed by largemouth bass. While total bluegill biomass was reduced and bluegill biomass distributions were shifted toward larger individuals, bluegill remained abundant in the presence of largemouth bass.

Abstract:
We used muscle-derived lactate dehydrogenase (LDH) to measure effects of prey size and vegetation density on anaerobic foraging activity by largemouth bass (Micropterus salmoides). Largemouth bass (240–303 mm total length, TL) were fed bluegill (Lepomis macrochirus) prey (range 33–83 mm TL) in laboratory feeding trials. Prey selectivity experiments showed that small bluegills (<50 mm) were strongly preferred (>88%) over larger (>65 mm) individuals. Largemouth bass activity, as indexed by LDH, increased with increasing prey size and was 20% higher in fish feeding on large (mean size = 80 mm) versus small (mean size = 35 mm) bluegill. Bioenergetics modeling revealed that food consumption was appreciably underestimated (29%–34%) for largemouth bass foraging on large bluegills (65 and 80 mm), implying that activity costs vary with prey size, consistent with LDH measurements. In contrast to prey size, vegetation density had little effect on anaerobic energy expenditure of largemouth bass. For two size groups of largemouth bass (mean = 244 and 316 mm) foraging on 50 mm bluegill, mean LDH activity was similar across simulated vegetation densities ranging from 70 to 350 stems·m–2. These findings highlight the importance of prey size on foraging costs by piscivores and the difficulties of accounting for activity level in bioenergetics models.

Abstract:
Estuaries are productive, heterogeneous, and dynamic systems that support a diverse array of fishes. However, our understanding of how presumably stenohaline fishes persist in such transitional systems is limited, particularly for most fishes in tidal freshwater areas. We conducted a laboratory experiment and field investigation along an upstream–downstream salinity gradient in the Mobile–Tensaw River Delta, Alabama, USA, to test the hypothesis that age-0 largemouth bass ( Micropterus salmoides ), an economically and ecologically important freshwater species that uses low-salinity habitats in many North American estuaries, move to avoid seasonal salinity increases. To do so, we quantified changes in otolith microchemistry (e.g., Sr to Ca ratios) along the major growth axis of otoliths in both field-collected and laboratory-reared individuals. Our experiment revealed a 21-day lag time between initial salinity changes and Sr:Caotolith saturation but that Sr:Caotolith in field-collected fish reflect changes in ambient salinity. Further, contrary to our expectation, otolith microchemical analyses from spring- and fall-collected age-0 largemouth bass indicate no avoidance of increased salinity, which has potential implications for their growth and recruitment in these systems.

Abstract:
Fish behavior types can predict angling vulnerability, providing insights about how recreational fishing may lead to artificial trait selection. Most vulnerability studies have focused on species with active foraging strategies, and the impact of environmental conditions on vulnerability has not been quantified. The objective of this study was to determine the influences of behavior types and habitat on angling vulnerability of largemouth bass (Micropterus salmoides (Lacepède, 1802)) — a sit-and-wait predator. Behavior assays quantified individual activity and boldness, then experimental angling took place in ponds with two habitat treatments: (1) structured habitat with artificial structures present and (2) open habitat with no structures added. Two anglers determined which individual largemouth bass were vulnerable to capture across the two contexts. In contrast with previous studies involving active foragers, behavior types of largemouth bass did not influence capture, regardless of habitat type. The number of captures also did not differ between structured and open habitat. However, anglers captured fish with different behavioral phenotypes, revealing additional complexity for factors that may affect behavioral selection. Findings suggest that angling may not be selecting for specific activity or boldness phenotypes of largemouth bass, even across habitat types, but that anglers may influence selection.

Abstract:
Nocardia seriolae is the causative agent of nocardiosis in both marine and freshwater fish. Here, we report on multiple outbreaks of nocardiosis associated with elevated mortality (23-35%) in farmed largemouth bass in Sichuan, China, from 2017 to 2018. A total of 9 strains isolated from diseased largemouth bass were identified as N. seriolae by phenotypic characterization, 16S rRNA and hsp65 gene sequence analysis. The clinical signs of infected largemouth bass included hemorrhage, skin ulcers and prominent tubercles varying in size in the gill, liver, spleen and kidney. Experimental infection indicated that these isolates were the pathogens responsible for the mortalities. In vitro antibacterial activities of 12 antibiotics against N. seriolae isolates were determined as minimum inhibitory concentrations. Histopathological observation of diseased fish infected with N. seriolae showed necrotizing granulomatous hepatitis, nephritis, splenitis, epithelial hypertrophy and hyperplasia with degenerative changes of the epithelium in the gill. Large quantities of bacterial aggregates were found in the necrotic area of the granuloma by Lillie-Twort Gram stain and immunocytochemistry. Our findings indicated that N. seriolae is a serious threat to the largemouth bass Micropterus salmoides industry in Southwest China.

Male smallmouth bass (Micropterus dolomieu) and largemouth bass (Micropterus salmoides) care for their offspring from fertilization until the offspring disperse after becoming capable of avoiding predators. We used activity transmitters to monitor round-the-clock parental activity of both species throughout the nesting period, coupled with direct observational data collected while snorkeling, to determine whether nocturnal behaviour varied similarly to diurnal behaviour. In general, nesting males of both species were equally active during day and night, developmental-stage-specific patterns being evident during both periods. Consistent with theory, parental males of both species exhibited elevated levels of burst swimming (indicative of chasing nest predators) early in the nesting period. Unlike male smallmouth bass, however, male largemouth bass showed no decline in overall activity and energy expenditure in the later nesting stages as predicted from the greater mobility and dispersion of their broods, although burst-swimming activity decreased. Activity of nesting fish was approximately double that of non-nesting conspecifics, causing an increase in respiration rates of fish, estimated using a bioenergetics model. The results of our study suggest that physiological telemetry devices which provide both behavioural and energetic information enhance the study of parental care activity in centrarchid fishes, and may be equally useful in a variety of other taxa.

Abstract:
HighlightsLight design is needed in recirculating aquaculture systems.A long photoperiod is beneficial to largemouth bass growth.Low light intensity is beneficial to largemouth bass growth.Abstract. In this study, recirculating aquaculture systems (RAS) were used to culture juvenile largemouth bass, and the effects of LED light intensity and photoperiod on the survival and growth performance of juvenile largemouth bass were studied. In the light intensity experiment, largemouth bass juveniles with an initial weight of 0.53 ±0.02 g were subjected to a two-month feeding experiment under two different light intensities: group A, at 0.5 W m-2 in the first month and 5 W m-2 in the second month; and group B, at 5 W m-2 in the first month and 0.5 W m-2 in the second month. The results showed that in the first month of the experiment, the growth rate of fry was faster in group A than in group B. After changing the light intensity, the weight of the fry in group B after one month of growth had exceeded and was significantly higher than that in group A. Based on the above experimental results, we conducted a photoperiod experiment. Largemouth bass juveniles with an initial weight of 0.56 ±0.02 g were cultured for two months under four different photoperiods (24L:0D, 16L:8D, 8L:16D, and 0L:24D). The light intensity of the four groups was 0.5 W m-2. The fry growth rate was fastest in the 24L:0D photoperiod group and slowest in the 0L:24D photoperiod group. The growth rate of the 24L:0D photoperiod group was significantly higher than that of the 0L:24D photoperiod group (p &lt; 0.05). The final fry weight was highest in the 24L:0D group, followed by that in the 16L:8D group and 8L:16D group, with the lowest weight observed in the 0L:24D group (p &lt; 0.05). Although the different light conditions in the two experiments had no significant effect on the survival rate of juvenile largemouth bass (p &gt; 0.05), a low-intensity light environment with a continuous photoperiod during the juvenile largemouth bass culture process promoted growth and development.

Abstract:
Largemouth bass (Micropterus salmoides) and northern pike (Esox lucius) are top predators in the food chain in most aquatic environments that they occupy; however, limited information exists on species interactions in the northern reaches of largemouth bass distribution. We investigated the seasonal food habits of allopatric and sympatric assemblages of largemouth bass and northern pike in six interior lakes within Voyageurs National Park, Minnesota. Percentages of empty stomachs were variable for largemouth bass (38-54%) and northern pike (34.7-66.7%). Fishes (mainly yellow perch, Perca flavescens) comprised greater than 60% (mean percent mass, MPM) of the northern pike diet during all seasons in both allopatric and sympatric assemblages. Aquatic insects (primarily Odonata and Hemiptera) were important in the diets of largemouth bass in all communities (0.0-79.7 MPM). Although largemouth bass were observed in the diet of northern pike, largemouth bass apparently did not prey on northern pike. Seasonal differences were observed in the proportion of aquatic insects (P = 0.010) and fishes (P = 0.023) in the diets of northern pike and largemouth bass. Based on three food categories, jackknifed classifications correctly classified 77 and 92% of northern pike and largemouth bass values, respectively. Percent resource overlap values were biologically significant (greater than 60%) during at least one season in each sympatric assemblage, suggesting some diet overlap.

Abstract:
Climate-related changes in fish communities can present new challenges for fishery managers who must address declines in cool- and cold-water sportfish while dealing with increased abundance of warm-water sportfish. We used largemouth bass (Micropterus salmoides) in Wisconsin lakes as model populations to determine whether angler harvest provides a realistic method for reducing abundance of a popular warm-water sportfish that has become more prevalent and has prompted management concerns around the globe. Model results indicate largemouth bass will be resilient to increased fishing mortality. Furthermore, high rates of voluntary catch-and-release occurring in most largemouth bass fisheries likely preclude fishing mortality rates required to reduce bass abundance at meaningful levels (≥25% reductions). Increasing fishing mortality in these scenarios may require more “stimulus” than merely providing anglers with greater harvest opportunities via less stringent harvest regulations. Angler harvest could result in populations dominated by small fish, a scenario that may be undesirable to anglers, but could provide ecological benefits in certain situations.

Abstract:
Lakes respond heterogeneously to climate, with implications for fisheries management. We analyzed walleye (Sander vitreus) recruitment to age-0 in 359 lakes in Wisconsin, USA, to (i) quantify the relationship between annual water temperature degree days (DD) and walleye recruitment success and (ii) identify the influence of lake characteristics — area, conductivity, largemouth bass (Micropterus salmoides) catch rates, and mean DD — on this relationship. The relationship between walleye recruitment and annual DD varied among lakes and was not distinguishable from zero overall (posterior mean = −0.11, 90% CI = −0.34, 0.15). DD effects on recruitment were negative in 198 lakes (55%) and positive in 161 (45%). The effect of annual DD was most negative in lakes with high largemouth bass densities, and, on average, the probability of recruitment was highest in large lakes with low largemouth bass densities. Conductivity and mean DD influenced neither recruitment nor the effect of annual DD. Walleye recruitment was most resilient to warming in lakes with few largemouth bass, suggesting that the effects of climate change depend on lake-specific food-web and habitat contexts.

Abstract:
Abstract Because of growing interest in producing Largemouth bass (HMB) as a source of high-quality protein for human consumption worldwide, it is imperative to understand the metabolism of nutrients (including amino acids and carbohydrate) in this aquatic animal. The present study tested the hypothesis that amino acids are oxidized at a higher rate than carbohydrates (e.g., glucose) and fatty acids (e.g., palmitate) to provide ATP for tissues of LMB fed a 45%-crude protein diet. The liver, intestine, kidney, and skeletal muscle were isolated from juvenile LMB and incubated at 26 °C (the body temperature of LMB) for 2 h in 1 ml of oxygenated Krebs–Henseleit bicarbonate buffer (pH 7.4) containing a mixture of nutrients (2 mM glutamate, 2 mM glutamine, 2 mM aspartate, 2 mM alanine, 2 mM leucine, 5 mM glucose, and 2 mM palmitate). The rate of oxidation of each energy substrate was determined by using [U-14C]-labeled glutamate, glutamine, aspartate, alanine, leucine, glucose, or palmitate and collecting 14CO2 from each tracer. Results indicated that aspartate, glutamate and glutamine were extensively oxidized in all the four tissues and contributed to 67% of total ATP production. Glutamate contributed to more ATP than glutamine in the intestine, whereas similar amounts of ATP were produced from glutamate and glutamine in the liver, kidneys and skeletal muscle. In all the four tissues, rates of oxidation of alanine, leucine, palmitate and glucose were low and each of those nutrients contributed to &lt; 10% of total ATP production. Together, the oxidation of aspartate, glutamate, glutamine, alanine plus leucine provided 82–85% of total ATP for the liver, intestine, kidney, and skeletal muscle. We conclude that amino acids, rather than glucose and long-chain fatty acids, are the primary energy substrates in the major tissues of Largemouth bass.
