“…A similar incidence of swim bladder overinflation was observed in larvae and juveniles of Lota lota and also in this species the reasons remained unknown (Rekecki et al, 2016). Failure in swim bladder inflation has been reported also for larvae of several marine species as Gadhus morhua (Grotmol, Kryvi, & Totlan, 2005), Latris lineata (Trotter, Pankhurst, & Hart, 2001) and Dicentrarchus labrax (Peruzzi, Westgaard, & Chatain, 2007) under intensive culture conditions. In Gadhus morhua it has been claimed that larvae are hypersensitive to moderate levels of gas super-saturation (< 119% total gas pressure) (King & Nardi, 2002), a parameter which can be excluded in the present experiments as fish fed with live feed did not develop swim bladder hyperinflation and gas oversaturation was not detected in unpublished measurement.…”

The present study investigates methods for larviculture and fingerling production in the European perch, Perca fluviatilis. Perch larvae in the stage of first feeding were sensitive to many manipulations necessary in fish culture. Lowering and increasing the tank water level as required for cleaning and water renewal, water flow and aeration led to disturbed buoyancy or mortality in a distinct percentage of larvae. Paramecium caudatum, wild zooplankton containing > 70% copeopds, and formulated dry feed were used for first feeding in combination with flow through tanks or static tanks. For first feeding Paramecium caudatum in combination with a static tank system was optimal resulting in survival rates of circa 90% at 15 days post hatch (dph). Wild zooplankton was no optimal starter feed as perch fed non-selectively on any feed particle available. This resulted in moderate survival rates of circa 50% at 15 dph. First feeding with formulated dry feed caused malformations (enlargement of swimbladders) and a high mortality of > 80%. Weaning from Paramecium caudatum to formulated dry feed and to zooplankton was tested on 8-16 dph larvae. Perch accepted the new food type within 3 days. The optimal time point for zooplankton weaning was 12 dph. In this age larvae had developed a selective feeding behaviour, and fed mainly on nauplii and copepodites. Weaning to formulated dry feed was impossible as larvae developed malformations resulting in high mortality as described above. Weaning from wild zooplankton to formulated dry feed was possible for larvae ≥ 29 dph. No cannibalism was observed in the experiments. The method was also tested in large scale experiments resulting in a survival rate of 65±4%, a total length of 45.0±7.2 mm, and a body weight of 1097±293 mg at 75 dph.

“…In discus larvae, the start of feeding activity coincided with the development of swim bladder at 4-5 DAH. Similarly, it was reported that swim bladder inflation coincided with the start of feeding activity in freshwater species such as Nile tilapia, Oreochromis niloticus, Mozambique tilapia, Oreochromis mossambicus, and walleye, Stizostedion vitreum (Marty et al 1995;Takemura 1996;Morrison et al 2001) and marine species such as Dover sole, Solea solea and striped trumpeter, Latris lineata (Boulhic and Gabaudan 1992;Trotter et al 2001). However, the timing of inflation in discus larvae was earlier than in many other species; for example, in the mouth-brooder cichlid, Oreochromis mossambicus, it was reported that inflation occurs 7-9 DAH, whereas in walleye and striped trumpeter, swim bladder inflates at 6-12 and 11-20 DAH, respectively.…”

Histological development of digestive tract in discus, Symphysodon spp. larvae

The present study provides information on the histomorphological development of digestive system of discus, Symphyosodon spp., larvae during the first month of life. Discus larvae are altricial at hatching, with an undifferentiated digestive tract and a large yolksac, which is completely consumed within 7 days. The mouth opens 3 days after hatching (DAH) and the larvae starts feeding on AF Artemia at 4 DAH when offered. At 3 DAH the digestive tract is differentiated with distinct esophagus, stomach anlage, and mid-and hindguts. At 5 DAH, discus larvae is an active feeder, equipped with partly developed jaws and ossified gill arches and an inflated swim bladder. The liver and pancreas are present and supranuclear inclusion vacuoles (SIV) appear in the hindgut for the first time. Gastric glands in stomach were first observed 7 DAH and proliferated by 11-13 DAH. SIV were a common feature in the midgut and hindgut epithelium until 15-23 DAH. Therefore, exclusive use of artificial diets should be postponed until 2-3 weeks after hatching.

“…In A. chalcoide, eye pig mentation occured on 2 DAH, prior to the mouth opening (3DAH) and exogenous feeding (6DAH), which might be attributed to the need to develop a function visual system before the first feeding (Hall et al, 2004). In many species such as Dover sole Solea solea (Boulhic and Gabaudan 1992), walleye Stizostedion vitreum (Marty et al, 1995), striped trumpeter Latris lineate (Trotter et al, 2001) and discus Symphysodon spp. (Önal et al, 2010), swimbladder inflation coincided with yolk sac depletion and the start of feeding activity.…”

M orphological development and allometric growth were investigated in hatchery -reared Capsian shemaya, Alburnus chalcoides, from hatching to the juvenile stage at a temperature of 25.13± 1.61℃. The newly hatched larvae were 4.69±0.27 mm in total length (L T ). M outh opened 3 days after hatching (DAH) and initial swimbladder inflation occurred at 5 DAH. Exogenous feeding started at 6 DAH and the yolk sac was completely exhausted one day later. Squamation was initiated at 46 DAH and completed until 57 DAH. Based on the external morphology, early development of A.chalcoides was divided into five periods: yolk-sac stage 0-6 DAH (4.69-7.61 mm L T ), preflexion stage 7-9 DAH (7.73-7.88 mm L T ), flexion stage 10-18 DAH (8.20-9.60 mm), postflexion stage 19-45 DAH (9.30-19.97 mm L T ) and juvenile stage 46-57 DAH (21.66-27.25 mm L T ). During the first 4 weeks after hatching, there was an evident priority to develop feeding, swimming and respiratory ability by promoting intense growth in head and tail parts. Following this period, there was a clear reduction in growth coefficients.The allometric growth changes in Capsian shemaya during early life reflect the selective organogenesis directed towards survival priorities.
