Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 10 - 13; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 10 - 13; गुदा कांटा: 3; ऐनल सौफट रेज़: 8 - 10. The upper body can vary from silvery to golden brown, bronze, green or black depending on habitat. Chin and belly are usually white and fins are dusky to greenish black. Dorsal and ventral profiles of adults are similarly convex.

Endemic in coastal areas, rivers and estuaries of Australia. Most abundant in river mouths and estuaries (Ref. 28468, 28472). Inhabit brackish waters of coastal rivers and lakes, occasionally penetrating fresh water (Ref. 44894). Considered as the only true estuarine sparid in Australia. Larvae and small juveniles are most abundant over seagrass beds in shallow estuarine waters (Ref. 28468, 28472). Spawning period varies considerably between estuaries (Ref. 28468). Remain upstream in sheltered waters to spawn and is not usually found in purely marine habitats (Ref. 44894). Feed on shellfish, worms, crustaceans, small fish and algae. Sold as whole, chilled products in domestic markets (Ref. 6390). One of top angling species in southern Australia (Ref. 6390, 44894), as well as being a delicious table fish (Ref. 2156).

Estimates based on models

Preferred temperature (Ref. 123201): 14.7 - 20.6, mean 17.6 °C (based on 126 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01259 (0.01140 - 0.01390), b=3.04 (3.01 - 3.07), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.53 se; based on food items.

Generation time: 4.1 (3.7 - 6.9) years. Estimated as median ln(3)/K based on 16 growth studies.

लौटाव (Ref. 120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (K=0.11; tm=2-5; tmax=29).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (41 of 100).

Price category (Ref. 80766): Very high.

Nutrients (Ref. 124155): Calcium = 76.4 [42.1, 142.3] mg/100g; Iron = 1.07 [0.62, 1.89] mg/100g; Protein = 20 [19, 21] %; Omega3 = 0.36 [0.25, 0.57] g/100g; Selenium = 21.1 [10.4, 38.9] μg/100g; VitaminA = 9.49 [3.31, 24.31] μg/100g; Zinc = 0.832 [0.594, 1.137] mg/100g (wet weight);
