How to Identify Different Types of Bream
Bream are a popular group of freshwater and saltwater fish known for their distinctive body shapes and sporting qualities. Anglers and fish enthusiasts alike often seek to identify various types of bream for recreational fishing, culinary purposes, or ecological study. However, with multiple species sharing similar characteristics but differing in subtle ways, identifying different types of bream can be challenging. This article provides a detailed guide on how to recognize and differentiate various bream species based on physical traits, habitats, and behaviors.
What is a Bream?
The term “bream” is commonly used to refer to several species of fish that belong to different families depending on the region. Generally, bream are medium-sized fish with deep, laterally compressed bodies and are found in both freshwater and marine environments.
In Europe, “bream” often refers to the common bream (Abramis brama), a freshwater species found in lakes and slow rivers. In Australia and New Zealand, the name applies to several marine species such as the silver bream, yellowfin bream, and black bream belonging to the Sparidae family. In North America, some species like the bluegill or other sunfish varieties can colloquially be referred to as bream.
Understanding these regional differences is essential when trying to identify specific types of bream.
Key Characteristics to Identify Bream
Before diving into specific species, here are general characteristics that define most bream:
- Body Shape: Deep-bodied and laterally compressed.
- Fins: A single dorsal fin that may be spiny in front and softer towards the rear.
- Mouth: Usually small or moderately sized, sometimes with specialized lips.
- Scales: Relatively large, often shiny and reflective.
- Size: Typically ranges from small (15 cm) to medium size (up to 60 cm or more depending on species).
With these shared traits in mind, look closely at other identifying features such as color patterns, fin shape, habitat preference, and behavior for accurate identification.
Common Types of Bream and How to Identify Them
1. Common Bream (Abramis brama)
Habitat: Freshwater lakes and slow-moving rivers across Europe and parts of Asia.
Appearance:
- Body: Deep and laterally compressed with a high back.
- Color: Generally silvery bronze or brownish on the back with lighter sides.
- Fins: The dorsal fin is long with a smooth outline; tail fin is forked.
- Mouth: Small and downward-facing used for bottom feeding.
- Size: Typically 30–55 cm long.
Identification Tips:
The common bream’s most distinctive feature is its flat belly combined with a high back giving it a rhomboidal shape. Its mouth is positioned low on the head which helps distinguish it from other freshwater fish. During spawning season, males may develop rough patches (nuptial tubercles) on their bodies.
2. Silver Bream (Blicca bjoerkna)
Habitat: Freshwater rivers and lakes in Europe, often sympatric with common bream.
Appearance:
- Body: Similar shape but generally slimmer than common bream.
- Color: Silvery with a pale golden hue on the flanks.
- Fins: Dorsal fin has 8–9 spines; tail fin less deeply forked.
- Mouth: Slightly upturned compared to common bream.
- Size: Smaller than common bream, usually around 20–35 cm.
Identification Tips:
Silver bream have more pronounced silvery scales giving them a flashier appearance. Their mouths tend slightly upwards compared to common bream’s downturned mouth. They also have thinner bodies and more delicate fins.
3. Black Bream (Acanthopagrus butcheri)
Habitat: Estuarine and coastal waters of southern Australia.
Appearance:
- Body: Deep-bodied but more robust than freshwater bream.
- Color: Usually dark gray or blackish on the back with silver sides.
- Fins: Dorsal fin has long spines; pectoral fins are rounded.
- Mouth: Strong jaws with molar-like teeth for crushing shells.
- Size: Can grow up to 50 cm or more.
Identification Tips:
Black bream’s darker coloration combined with its sturdy body distinguishes it from lighter-colored silver or yellowfin bream. It also has a more aggressive mouth structure suited for crushing mollusks which is visible upon close inspection.
4. Yellowfin Bream (Acanthopagrus australis)
Habitat: Coastal waters from southern Queensland down through New South Wales in Australia.
Appearance:
- Body: Oval-shaped, moderately deep-bodied.
- Color: Silvery with distinct yellow coloring on the fins—especially the pectoral and anal fins.
- Fins: Sharp dorsal spines; yellow tint on fins is very distinctive.
- Mouth: Small mouth adapted for omnivorous feeding habits.
- Size: Usually up to 40 cm.
Identification Tips:
The defining feature is its yellow fins which contrast strongly against its silver body. This makes it one of the easiest Australian species to identify. The yellowfin’s smaller mouth compared to black bream also helps distinguish between the two when caught.
5. Gilt-head Bream (Sparus aurata)
Habitat: Mediterranean Sea and eastern Atlantic Ocean coastal waters.
Appearance:
- Body: Deep-bodied with a compressed oval shape.
- Color: Silver-gray body with a prominent golden bar or “gilt” between the eyes.
- Fins: Single dorsal fin with both spiny and soft rays.
- Mouth: Strong teeth arranged in a beak-like arrangement for crushing prey.
- Size: Can reach up to 70 cm.
Identification Tips:
The trademark golden bar across its forehead makes gilt-head bream unmistakable among Mediterranean species. Its body shape is also more oval compared to other breams which tend toward rhomboidal forms.
6. Bluegill Sunfish (Colloquially Called Bream in North America)
Habitat: Freshwater lakes and rivers throughout North America.
Appearance:
- Body: Deep, laterally compressed body typical of sunfish family.
- Color: Olive green with blue or purple highlights on cheeks and gill covers; vertical bars along sides.
- Fins: Spiny dorsal fin connected seamlessly to soft dorsal fins.
- Mouth: Small mouth suitable for insectivorous diet.
- Size: Usually around 15–25 cm.
Identification Tips:
Bluegill are often referred to as “bream” by anglers in parts of the US South due to their similar size and shape. Their distinctive blue markings around the gill cover are key identifiers among freshwater anglers.
Additional Identification Factors
Habitat & Behavior
Knowing where you catch or observe the fish can greatly narrow down possibilities:
- Freshwater lakes/rivers in Europe often house common or silver bream.
- Estuaries or coastal waters in Australia likely contain black or yellowfin bream.
- Mediterranean coastal waters suggest gilt-head bream presence.
Behavioral clues include feeding habits—bottom feeders like common bream have downward mouths; omnivores like yellowfin feed higher in water column; black bream crush mollusks indicating strong jaw structure.
Scale Counts & Fin Ray Numbers
For professional identification, counting scales along lateral lines or rays in dorsal/anal fins can help confirm species since these counts differ subtly but consistently among species. For example:
- Common Bream typically has 39–43 scales along lateral line.
- Silver Bream often has fewer lateral line scales (around 35–39).
Such detailed measurements require close examination but are invaluable for scientific accuracy.
Color Changes During Breeding
Some bream change colors during spawning season:
- Male common bream develop darker coloration with rough patches (nuptial tubercles).
- Black bream males turn almost jet black during breeding times.
Noticing these changes can help time identification efforts better during different seasons.
Summary
Identifying different types of bream requires attention to subtle physical characteristics such as body shape, coloration, fin structure, mouth orientation, and size combined with knowledge about their habitats and behaviors. Regional variations mean that knowing where you found your catch plays an essential role alongside visual traits.
Here’s a quick review:
