BADHAM, M. (1973)

Breeding the Indian smooth otter Lutrogale perspicillata sindica X L.p. perspicillata at Twycross Zoo.

International Zoo Yearbook 13: 145-146.
https://doi.org/10.1111/j.1748-1090.1973.tb02132.x

Zusammenfassung:

1.1 Glattotter wurden ab Juli 1971 in einem Gehege mit einem Landteil von 300 m² und einem Becken von 12 m² / 22.7 m³ gehalten. Am 7. November gebar das Weibchen ein Jungtier. Da sie dieses ständig zwischen dem Innenraum und einem selbstgegrabenen Erdbau hin- und her transportierte, wurde das Junge ab dem 3. Lebenstahg von Hand aufgezogen. Es dürfte dies der erste Zuchterfolg außerhalb Süd-/Südostasiens gewesen sein.

BALDASSIN, P.I., GALLO, H.I. & AZEVEDO, V.G.

Reprodution of the Cownose ray, Rhinoptera bonasus Mitchill, 1815 (Elasmobranchii, Rhinopteridae), in captivity and newborn care.

Braz. J. Biol. vol.68 no.4 São Carlos Nov. 2008
https://doi.org/10.1590/S1519-69842008000400029  

Kurzmitteilung, Auszug:

Since its opening in 1996, the Ubatuba Aquarium, located in Ubatuba, São Paulo State, Brazil, has three specimens of the cownose ray, one male and two females, held in an 85000l tank. It is a semi-open system with biological and mechanical filtration, skimmer, and UV and ozone water sterilization. The tank is illuminated by metal halide lamps and for half the day by direct sunlight.

In September 2003, courtship behavior was observed, and only one quick copulation during the afternoon, with one clasper insertion followed by white liquid spreading out from the female cloacae. During courtship, mating and gestation period, average physical and chemical parameters values monitored in the water tank were: pH7.3, 0.25 ppm NH3, 0.25 ppm NO2, salinity 34 ppm and temperature 26 °C. Finally, after 13 months gestation, in November 1st 2004, at dawn, the female gave birth to a male offspring.

The pup was born with 38 cm disc width and weighing 3.75 kg.

PFLEIDERER, J. (2019)

Wiederholter Nachwuchs bei den Madagaskar-Riesenratten im Zoo Duisburg.

Eliomys 2019/1: 36-37.

Der Volksmund bezeichnet als "Ratte" diejenigen Nagetiere, deren lange Schwänze kahl und deren Körper vergleichsweise riesig ist. So gesehen passt die Madagaskar-Riesenratte (Hypogeomys antimena GRANDIDIER, 1869) voll ins Schema. Allerdings hat sie mit unseren heimischen Kanalratten so gar nichts gemein. Diese gehören einer anderen Nagerfamilie an.. Die Madagaskar-Riesenratte lebt auf der gleichnamigen Insel und erscheint aufgrund der recht langen Ohren etwas kaninchenähnlich. In europäischen Zoos ist sie selten vertreten, in Deutschland hält sie nur der Zoo Duisburg, der sie auch erfolgreich züchtet.

Natural spawning, early development and first feeding of the semicircle angelfish [Pomacanthus semicirculatus (Cuvier, 1831)] in captivity.

Aquaculture Research 40 (9): 1019-1030. https://doi.org/10.1111/j.1365-2109.2009.02192.x


Abstract:

Successful natural spawning of Pomacanthus semicirculatus in captivity from 11 September to 18 October, 2006 is described for the first time. Each female laid an average of 230 000 ( sic ?!) eggs during the spawning period. Fertilized eggs were spherical, transparent and buoyant and had a mean diameter of 0.61 ± 0.03 mm (mean ± SD). Embryonic development lasted 18–21 h at 28.5 °C. Newly hatched larvae were 1.35 ± 0.02 mm in total length (TL) with 27 (12+15) myomeres and had an oil globule in the ventroposterior area of the yolk sac. Larvae completed yolk absorption within 3 days post hatching at 2.37 ± 0.05 mm TL. Larvae were fed either 100% microalgae (Nannochloropsis sp.), 100% s‐type rotifers (Brachionus rotundiformis), 100% dinoflagellates (Gonyaulax sp.) or different combinations of the three (50%:50%:0%, 30%:35%:35%) to determine the effect of live feed on the survival rate. The survival was significantly (P<0.001) better in larvae fed a combination of diets (30%: 35%: 35%) than others. These results indicate that P. semicirculatus is a potential species for captive‐breeding programmes and the use of a combination of diets (microalgae plus s‐type rotifers and dinoflagellates) may be a suitable first food for fish larvae.

Coral reef fish breeding: the secrets of each species.

Aquaculture 224 (1-4): 69-78

Abstract

In recent years, the interest in the trade of tropical fish has increased significantly, with direct negative repercussions on coral reefs and marine ecosystems.

The reproduction and rearing of some of the species most commonly used in the aquarium trade actually represent an economical and ecological tool for broadening development. The present study illustrates the first case ever of a small Indo-Pacific Pomacentridae, Chrysiptera parasema, successfully reared in captivity. Eggs were obtained from spawners reared in 80-l tanks under controlled conditions. Spawning began after 3 months: the couples were formed, and eggs were laid after a brief courtship. The male normally guarded the nest and chased away the female if she entered it.

The eggs, about 300 in number, are demersal and elongate ovoidal in shape, measuring approximately 1.2–1.5 mm and coming with a large oil globule. Hatching took place at 28 °C during the first 2 h of darkness, over a total time period of 96 h. A proper diet of enriched PUFA as a first food, combined with a photoperiod of 24L/0D, proved essential for survival of the C. parasema larvae.

These results are very promising in terms of both future captive production of ornamental fish and efforts to minimize environmental impact.
