The bluespotted sunfish (Enneacanthus gloriosus) is a species of fish in the family Centrarchidae, the sunfishes. It is native to the southeastern and eastern United States, its distribution extending as far north as New Jersey, Pennsylvania, and far southern New York. [1] [3] It is native throughout most of its range, but some populations represent introductions, such as those in Lake Ontario and the upper Susquehanna River system. [4]

Contents

In many areas, this fish is sympatric with a closely related member of its genus, the banded sunfish (E. obesus). The two species are hard to tell apart. They are known to hybridize. [5]

Description

This fish reaches about 9.5 centimetres (3.7 in) in maximum length. [6] It is one of the smallest fish in its family. [7] It has spines in its dorsal and anal fins. Its tail fin is rounded in outline. Its body is covered in white or blue dots. [6] Some individuals have iridescent spots. [5] There may be a few pale bars on its sides, [6] but these are rare, especially in adults. [5]

A number of parasitic flatworms have been observed in this fish, such as Gyrodactylus gloriosi and several Urocleidus species. [8]

Habitat

Several aspects of the life history of the fish vary geographically. Fish on the East Coast and in Florida are larger than individuals in Mississippi, for example. The fish becomes sexually mature at larger sizes in more northern latitudes. This may be because fish in milder climates can begin reproductive investment earlier, putting their energy into gonadal growth instead of body growth at younger ages. Fish in the east can reach a maximum age around 5 years, but fish in the south generally do not reach that age. The spawning season is also much longer in southern regions, probably because of warmer temperatures and longer photoperiod. [9]

This freshwater fish occupies ponds, lakes, creeks, streams, and medium-sized rivers. It can tolerate slightly brackish water in areas near the coast. It thrives in small backwaters filled with vegetation and tree roots. [1] [3]

This species is sometimes kept as an aquarium pet. [6] [10]

Reproduction

The fish spawns several times in a season, sometimes daily for a long period of time. [9] The male builds a nest in the substrate or in plant matter. [1] Clutch sizes of 42 to 216 have been observed. [9]

Diet

The diet of the fish is rich in plankton. It consumes cyclopoid copepods, water fleas, midge larvae, ostracods, [6] amphipods, and snails. [10] Its preference for tiny aquatic larvae makes it a suitable mosquito control agent. [11]

Orangespotted sunfish Species of fish

The orangespotted sunfish is a North American species of freshwater fish in the sunfish family (Centrarchidae) of order Perciformes. These fish are widely distributed across the middle and eastern United States, from the Rocky Mountains to the east, from the Great Lakes south into the Gulf Coast. The orangespotted sunfish is ecologically unique and thrives in turbid, shallow systems that have few predators and low oxygen contents. The species prefers vegetated areas in sluggish backwaters or lakes, and can also be found in turbid rivers. The orangespotted sunfish can extend its range in lower-quality waters, which is not characteristic to other sunfish. Orangespotted sunfish vary in total length and age for different river basin originations, but can be found to live four to seven years, and recorded lengths are up to 15 cm (5.9 in).

Golden topminnow Species of fish

The golden topminnow is a fish of the genus Fundulus and is a United States native fish mostly distributed throughout the southeast, ranging from Kentucky and Ohio south into Florida. Although it has such a wide distribution throughout the south, the habitats and micro-habitats that it occupies do not differ much from one area of distribution to others. The golden topminnow is a small surface feeding fish that tends to reproduce late in the spring season and on into the early parts of the summer, and although the fry reach maturity fairly quickly the longevity of the golden topminnow is quite short. Because the golden topminnow is lower in the trophic level and is a small fish, it primarily feeds on small and/or drifting organisms at, or near the surface of, vegetated areas. This particular topminnow is not currently listed as an endangered species, nor does it have any particular type of management plan.

It prefers densely vegetated bodies of slow-moving water. This species can reach 4.7 cm (1.9 in) in total length, though most do not exceed 3.5 cm (1.4 in).

Dollar sunfish Species of fish

The dollar sunfish is a species of freshwater fish in the sunfish family of order Perciformes. It is categorized as a warm water pan-fish. Early settlers said that this species of sunfish resembled a European species they called bream. Historically it has been found along the Southern Atlantic coastal drainages from North Carolina to Florida, and west to Texas. Lepomis marginatus mainly feeds on detritus and filamentous algae as well as a few terrestrial insects. The juvenile and mature fish do not have many predators, but the eggs in the nest are in danger of predation from a few different species of fish.

It is endemic to the southeastern United States where it is found in Gulf Slope streams from the Colorado River drainage in Texas to the Flint River in Georgia, the Atlantic Slope in Ocmulgee River system, Georgia, and the Mississippi embayment north as far as southeastern Missouri and western Kentucky. It is typically found in small springs, streams, and creeks with aquatic and marginal vegetation and detritus. The female spawns on multiple occasions between about mid-March and June, sticking the adhesive eggs to plants, gravel and the sides of rocks. The goldstripe darter is a common species with a wide range and numerous sub-populations, and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".

The Zenarchopteridae exhibit strong sexual dimorphism, practicing internal fertilisation, and in some cases ovoviviparous or viviparous. The members in the family are mainly found in fresh and brackish water of tropical Asia and New Guinea, but the genus Zenarchopterus also includes marine species from the Indo-Pacific. Several, such as the wrestling halfbeak, have become commonly traded aquarium fish.

Blackbanded sunfish Species of fish

The blackbanded sunfish is a freshwater fish species of the sunfish family (Centrarchidae). They are found in the United States ranging from New Jersey to central Florida.> The defining feature of this Black-banded sunfish is the black vertical strips that it has on both sides of its body. The term "Enneacanthus" comes from the Greek terms ennea, which means "nine times", and acanthi, which means "thorn". It is in a genus that consists of only three species along with the Banded Sunfish and the Bluespotted Sunfish. Collectively, they are commonly referred to as the "Banded Sunfish" or "Little Sunfish".

Halloween darter Species of fish

The Halloween darter is a small freshwater fish native to North America. It is found in Georgia and Alabama in the drainage basin of the Apalachicola River, specifically in the Flint River system and the Chattahoochee River system. It prefers shallow, fast-flowing areas with gravel bottoms in small and medium-sized rivers. It was first described in 2008, having not previously been distinguished from the blackbanded darter (P. nigrofasciata), which occurs in the same watershed. The color is somewhat variable, being generally blackish dorsally, with some individuals having indistinct saddle-like barring. Males have orange and dark lateral striping while females have dark stripes and a yellowish-green belly. At a maximum standard length of 101 mm (4 in), males are slightly larger than females, and both sexes develop distinctive orange barring on the edge of the first dorsal fin during the breeding season.
