Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 11; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 16 - 17; गुदा कांटा: 3; ऐनल सौफट रेज़: 11. Distinguished by the following characteristics: dark to olive-brown body color with purplish and lighter brown spots, or plain dark brown; xanthic morph is bright yellow all over; depth of body contained 2.9-3.2 times in SL; head length 2.6-2.9 times in SL; slightly convex interorbital area; angular preopercle, with serrate lobe at angle; posterior nostrils of adults much larger than anterior ones (Ref. 89707).

Found among rock walls, underwater lava ridges, and all kinds of well structured vertical rock formations (Ref. 11295). Juveniles found in shallow sandy lagoons (Ref. 5222), also in seagrass beds, mangrove lagoons, shallow lava reefs and inland lava ponds (Ref. 11295). Adults are mainly piscivorous, prey size increasing with predator size (Ref. 11295).

Estimates based on models

Preferred temperature (Ref. 123201): 14.5 - 23.7, mean 19.3 °C (based on 4 cells).

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

Bayesian length-weight: a=0.00603 (0.00365 - 0.00994), b=3.02 (2.88 - 3.16), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.80 se; based on food items.

लौटाव (Ref. 120179): माध्यम, न्यूनतम जनसंख्या दुगनी होने का समय 1.4 - 4.4 वर्ष। (K=0.18; tm=3; tmax=7).

Fishing Vulnerability (Ref. 59153): High vulnerability (61 of 100).

Price category (Ref. 80766): High.

Nutrients (Ref. 124155): Calcium = 63.5 [28.2, 126.1] mg/100g; Iron = 0.861 [0.465, 1.708] mg/100g; Protein = 18.1 [16.3, 19.8] %; Omega3 = 0.219 [0.129, 0.372] g/100g; Selenium = 66.8 [33.8, 142.8] μg/100g; VitaminA = 23.4 [7.5, 81.7] μg/100g; Zinc = 0.666 [0.455, 0.982] mg/100g (wet weight); based on nutrient studies.
