Eponymy: Bloch did not identify whom he was naming this fish after, but a probable candidate is Count Ewald Friedrich von Herzberg (1725–1795), a distinguished Prussian statesman and savant and one of Bloch’s sponsors. (Ref. 128868), visit book page.

Biology     Glossary (e.g. epibenthic)

Adults occur in turbid estuaries, mangrove-lined lagoons and lower parts of rivers being very tolerant to changes in salinity. Found on shallow soft bottoms (Ref. 5217). Feed on a large variety of bottom-living and pelagic organisms including those found among the roots of mangroves. Reproduction occurs between September and December. A female lays 20-30 eggs, with a diameter of 10-12 mm. Males incubate the eggs in their mouth (Ref. 35381).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Females reach maturity at a younger age than males and grow faster. The male incubates 28-40 eggs in the mouth and 200-400 eggs that are fixed in a glutinous mass on its head. Incubation takes 10-12 days. After 50-60 days fully functional young (6-6.5 cm TL) are released.

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00537 (0.00448 - 0.00644), b=3.15 (3.10 - 3.20), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level
(Ref. 69278) 		3.3   ±0.39 se; based on food items.
Generation time 3.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience
(Ref. 120179) 		Medium, minimum population doubling time 1.4 - 4.4 years (tm=2-3; Fec=200).
