Spotted Gar IMG_1369

REPRODUCTION: Spawns between the months of May and July. Eggs are simply scattered among aquatic vegetation, and no parental care is exhibited. The roe (or egg mass) is highly toxic to humans, animals, and birds.

PREDATORS: Eaten by larger fish, alligators and herons.

REMARKS: Have a specialized swim bladder which allows them to gulp air and live in the poorly oxygenated back waters.

They are primitive fish and date back to the Cretaceous period, some 65 to 100 million years ago. The ancestors of spotted gar swam with the dinosaurs.

Largemouth Bass 4515020403_327c45ebbd_b

GENERAL CHARACTERISTICS: Common length : 40.0 cm, (16 inches), max. published weight: 10.1 kg (22 1/4 lbs). Mouth large; maxillary extending beyond the eye. Green to olive dorsally, milk-white to yellow ventrally, with a black band running from the operculum to the base of the caudal fin. Caudal fin rounded

DISTRIBUTION/HABITAT: Native to eastern North America and historically ranged from southern Canada to northern Mexico, and from the Atlantic coast to the central region of the United States. Prefers quiet, shallow, clear water with lots of vegetation. Seldom found deeper than 20 feet.

DIET: Crayfish and other fish species including their own. Other sunfish species are the food of choice for most adult largemouth bass.

REPRODUCTION and DEVELOPMENT: Males prepare and build a crude nest in shallow water. Following an act of courtship, female lays eggs in the nest. Males guard the eggs until they hatch. The schooling fry remain close to their father for about a month.

TAXONOMY

KINGDOM Animalia
PHYLUM Chordata
CLASS  Actinopterygii (ray-finned fishes)
ORDER Gasterosteiformes (Sticklebacks and seamoths)
FAMILY Gasterosteidae (Sticklebacks and tubesnouts)
GENUS/SPECIES  Gasterosteus aculeatus

 

 

GENERAL CHARACTERISTICS

Common length : 5.1 cm or 2 in.  Identified by the 3 to 4 sharp, free spines before the dorsal fin, the pelvic fin reduced to a sharp spine and a small ray, the series of plates along the sides of the body and are usually mottled brown or greenish.

 

DISTRIBUTION/HABITAT 

 Coastal oceans in northern Europe, Asia and North America

 Freshwater streams, estuaries

 

DIET: worms, aquatic insects, fish eggs and fry

 

REPRODUCTION:  Red means ready.  At mating time, the chin and belly of male sticklebacks turn red. The brighter the red, the more enticing they are to the females they’re courting. Male sticklebacks weave rounded nests of algae, leaves and pebbles.   The neater the nest, the more likely a male is to woo a mate to lay her eggs inside. Once she does, he drives her out, guards and aerates the eggs until the hatch.
