This report is based on several years of intensive studies of the production and related population dynamics of six kinds of warmwater fishes maintained as single species in 1-acre ponds. Species involved included the largemouth bass, Micropteriis salmoides (Lacepede); smallmouth bass, M. dolomieiii Lacepede; bluegill, Lepomis macrochiriis Rafinesque; yellow perch, Perca flavescens (Mitchill); brown bullhead, Ictahiriis uebulosus (LeSueur); and the white crappie, Pomoxis annularis Rafinesque. Most production data published for these species have originated primarily from studies involving complex, multispecies populations. The principal aims of this investigation were to 1 ) increase our knowledge of the carrying capacities of ponds for warmwater fishes, 2) consider the relationship of carrying capacity to standing crop and to rate of production, and 3) measure the influence of controlled population increases and decreases on fish production.

Brood Guarding

Models of potential brood predators placed near the nest were used to elicit defence behaviour in male smallmouth bass (Micropterus dolomieui) in the field. The three predator models represented a conspecific, a species found in the lake (yellow perch, Perca flavescens), and a species not present in the lake (brown bullhead, Ictalurus nebulosus). Aggressive behaviour increased with brood age and with decreasing distance between model and nest. Brood-guarding smallmouth bass exhibited a generalized response to the three predator models and did not discriminate between them by altering levels of aggression.

The Impact

White perch (Morone americana), yellow perch (Perca flavescens), and smallmouth bass (Micropterus dolomieui) were acclimated to 5 and 20 °C. There was an increase in ventricle mass relative to body mass in smallmouth bass only following acclimation to 5° C. Maximal in vitro activities of hexokinase, citrate synthase, carnitine acyl CoA transferase (with palmitoyl CoA, palmitoleoyl CoA, and oleoyl CoA as substrates), and total ATPase were assessed in crude heart homogenates. Tissues removed from warm-acclimated animals were tested at 20 and 5 °C; tissues removed from cold-acclimated animals were assessed at 5 °C. Acute temperature transitions were associated with decreases in the activities of hexokinase (Q10 ≈ 1.8), citrate synthase (Q10 ≈ 1.4), and ATPase (Q10 ≈ 1.7). The impact of temperature on carnitine acyl CoA transferases was generally less severe. This suggests that maximal fatty acid oxidation is conserved better than glucose oxidation during a warm to cold transition. Maximal enzyme activities were generally unaffected by the acclimation regime, with the exception of that of carnitine acyl CoA transferase in white perch heart. The substantial increase in carnitine acyl CoA transferase activity when unsaturated CoA derivatives were provided as substrate suggests an increased capacity to oxidize unsaturated fatty acids at low temperature following an acclimation period. Attempts to sustantiate this contention by offering labelled oleic acid to ventricle sheets were thwarted by a high rate of incorporation into the total lipid pool.

Working Out

The writer has been working on the food plants of the leaf-hoppers for many years and has found in the main the different species of the genus Platymetopius, as commonly recognized, are very closely confined to a single species of plant or to a closely related group. Before it was possible to prepare a list of the food plants in the group it was found necessary to describe a number of new species of which food plant and life history information was available. In working out the relationship of these species, two startling discoveries were made.

The Relationship

Ten yearling yellow perch (Perca flavescens) were tested individually for 3-day periods in electronic shuttleboxes to determine their diel patterns of behavioral thermoregulation and of locomotor activity relative to a natural April photoperiod, and to determine the relationship between preferred temperatures and activity. The perch exhibited a diel rhythm of preferred temperature, with a predawn minimum of 16.7 °C and a dusk maximum of 23.8 °C. The 24-h mean was 20.2 °C; the diurnal mean was 21.5 °C and the nocturnal mean was 18.5 °C. Locomotor activity (quantified as mean photocell-monitored light-beam interruptions per hour) was crepuscular, with a major peak (25 units/h) at dusk, and a smaller peak (14.4 units/h) at dawn. Nocturnal activity was slightly greater (5.3 units/h) than diurnal activity (4.4 units/h). Locomotor activity relative to temperature exhibited a local minimum (0.4–6.2 units/h) at 22.2 °C.

Analysis of incidence and intensity of infestation of yellow perch, Perca flavescens (Mitchill), by the glochidia of Lampsilis radiata from weekly samples from May to September and single samples in October and November indicate that the two subspecies, Lampsilis radiata radiata and Lampsilis radiata siliquoidea, shed their glochidia in late spring and throughout the summer in the Bay of Quinte, Lake Ontario. Smaller fish are more heavily infested with these glochidia than larger ones. About 50% of the preparasitic glochidia of Lampsilis radiata siliquoidea survived for 12, 70, and 120 h at 20°, 12°, and 10 °C respectively. The parasitic period of the glochidia of L. r. siliquoidea on yellow perch under experimental conditions was 50 days at 15 °C from the May infestation. Yellow perch carried the glochidia for a longer period from an August infestation. All the glochidia recovered 50 days after infestation, both from May and August infestations, had undergone metamorphosis. There was no difference in the degrees of infestation of the different species of fish used in our experiments. Pumpkinseed, Lepomis gibbosus (Linnaeus); rock bass, Ambloplites rupestris (Rafinesque); and white perch, Roccus americanus (Gmelin) lost their infestations in a week. Presumably no metamorphosis took place under these conditions. Black crappie, Pomoxis nigromaculatus (LeSueur); largemouth bass, Micropterus salmoides (Lacepede), smallmouth bass, M. dolomieui Lacepede: and yellow perch carried the infestation till they were killed 20 days later. There was no relationship between the numbers of glochidia (Lampsilis radiata) and copepods, (Ergasilus confusus Bere) on naturally infested yellow perch, nor on rock bass, smallmouth bass, and pumpkinseed which harbored Ergasilus spp. naturally and which were infested with the glochidia of L. r. siliquoidea experimentally.

I determined experimentally the relative survival of similar-sized yellow perch (Perca flavescens), brook stickleback (Culaea inconstans), fathead minnow (Pimephales promelas), and finescale dace (Phoxinus neogaeus), individually and in all possible species combinations, in the presence of northern pike (Esox lucius). Overall, perch showed the highest, sticklebacks and dace the intermediate, and fatheads the lowest relative survival. Differential laboratory survival of prey demonstrates the utility of single species experiments in predicting the results of multiple prey and predator interactions. The results also support the hypothesis that piscivory can maintain the distinctness of assemblages of predation-tolerant and piscivorous species versus assemblages of predation-intolerant species.

The objective of this study was to quantify the physical characteristics of coarse woody structure (CWS) as fish habitat in a north temperate lake. Sixteen species of fish were observed in submerged CWS habitat. Branching complexity, distance above the bole, area below the bole, distance to other CWS, and water depth around CWS were significantly related to abundance of schooling cyprinids (Cyprinidae), rock bass (Ambloplites rupestris), smallmouth bass (Micropterus dolomieu), bluegill (Lepomis macrochirus), yellow perch (Perca flavescens), and walleye (Sander vitreus). Branching complexity was the most common characteristic of CWS related to richness, diversity, and total adult abundance of fish taxa, but was not correlated with the total lengths of fish found in submerged trees. Branching-complexity values ranged from 1 (simple) to 500 (moderately complex) in the littoral zone; for comparison, a living riparian conifer had a branching-complexity value of over 1000. Most CWS in the littoral zone was composed of simple trees without branching, but fish tended to inhabit CWS with branching-complexity values greater than 45. This study shows the importance of CWS with fine branching as littoral-zone fish habitat.

The Relationship

A recent examination of the relationship between O2 uptake (M(dot)O2) and diffusive sodium loss (JNaout) in a freshwater fish showed that Na+ losses after exhaustive exercise exceeded those expected on the basis of M(dot)O2, probably due to distortion of the paracellular tight junctions (the primary site of diffusive ion loss) and/or glomerular-type filtration caused by increased lamellar pressure. In the present study, an examination of this relationship in nine species of fish from diverse habitats supports this model. Under routine conditions, the rate of Na+ loss per unit of O2 consumed (termed the ion/gas ratio or IGR) was similar in all the species tested, averaging 61.6 pmol Na+ nmol-1 O2. After exhaustive exercise, the degree to which the IGR of each species increased relative to its routine levels (post-exercise IGR/routine IGR) was exponentially related to the relative rise in M(dot)O2, i.e. greater rates of O2 uptake led to even greater ion losses. Further analysis revealed that, although naturally active species had the lowest proportionate increase in M(dot)O2, by virtue of their high routine rates, they had the highest post-exercise rates of O2 uptake. In fact, there was an inverse correlation between post-exercise IGR and M(dot)O2, i.e. species with low M(dot)O2 values lost more Na+ per mole of O2 taken up than did species with high ones. Thus, naturally active species, such as the common and golden shiner, were able to achieve higher rates of O2 uptake while avoiding high rates of ion loss. Surprisingly, species such as banded sunfish, yellow perch and smallmouth bass did not limit ion loss associated with exercise despite their apparent ability to do so. They demonstrated a strong ability to limit ion losses caused by a brief osmotic shock and by exposure to soft water (both of which distort tight junctions).

Intertidal Fishes

While intertidal habitats are often productive, species-rich environments, they are also harsh and highly dynamic. Organisms that live in these habitats must possess morphological and physiological adaptations that enable them to do so. Intertidal fishes are generally small, often lack scales, and the diverse families represented in intertidal habitats often show convergence into a few general body shapes. However, few studies have quantified the relationship between phenotypes and intertidal living. Likewise, the diversity of reproductive traits and parental care in intertidal fishes has yet to be compared quantitatively with habitat. We examine the relationship of these characters in the sculpin subfamily Oligocottinae using a phylogenetic hypothesis, geometric morphometrics, and phylogenetic comparative methods to provide the first formal test of associations between fish phenotypes and reproductive characters with intertidal habitats. We show that the ability to live in intertidal habitats, particularly in tide pools, is likely a primitive state for Oligocottinae, with a single species that has secondarily come to occupy only subtidal habitats. Contrary to previous hypotheses, maximum size and presence of scales do not show a statistically significant correlation with depth. However, the maximum size for all species is generally small (250 mm or less) and all show a reduction in scales, as would be expected for an intertidal group. Also contrary to previous hypotheses, we show that copulation and associated characters are the ancestral condition in Oligocottinae, with copulation most likely being lost in a single lineage within the genus Artedius. Lastly, we show that body shape appears to be constrained among species with broader depth ranges, but lineages that occupy only a narrow range of intertidal habitats display novel body shapes, and this may be associated with habitat partitioning, particularly as it relates to the degree of wave exposure.

The Relationship

The octopus fauna from the southern Caribbean is an understudied field. However, recent taxonomic work in the Colombian Caribbean has led to the discovery of several new species in the family Octopodidae. To provide molecular evidence for recent descriptions in the area (i.e., Octopus taganga, O. tayrona and Macrotritopus beatrixi) and contribute to the systematics of the family, we reconstructed the first molecular phylogenies of the family including Colombian Caribbean octopus species. Using cytochrome c oxidase subunit I and rhodopsin sequences from specimens collected in three sites (Santa Marta, Old Providence and San Andrés Islands) we inferred maximum-likelihood trees and delimited species with PTP. Our mitochondrial analysis supported the monophyly of species found in the area (i.e., O. taganga, O. hummelincki and O. briareus). The genetic distinction of the species O. tayrona and O. insularis was not resolved, as these were found in one clade together with Caribbean O. vulgaris and O. aff. tayrona species (O. spB) and delimited as a single species. Additionally, our results suggest a distant relationship of the Type I O. vulgaris group (Caribbean region) from the other forms of the species complex (Old World and Brazil). Lastly, the third newly described species M. beatrixi emerged as an independent lineage and was delimited as a single species. However, its relationship to other species of its genus remains unknown due to the lack of sequences in databases. Altogether, our molecular approach to the octopus fauna from the southern Caribbean adds on information to the relationship of Octopodidae species world-wide by providing sequences from recently described species from an understudied region. Further studies employing higher taxon sampling and more molecular information are needed to fill taxonomic gaps in the area and account for single-locus resolution on the systematics of this group.
