Since 20th June 2009 is the Protivín Crocodile ZOO official member of the Conservation programme of Philippine crocodile. The Conservation programme is organized by Enviromental Goverment of the Republic of the Philippines (DENR) and the partner of the Protivín Crocodile ZOO is manila Avilon Widlife Conservation Foundation and School of Practical Veterinary Managment, Inc ( Avilon ZOO). From this ZOO ( Avilon ZOO), the Philippine crocodiles were imported to the Protivín Crocodyle Zoo – four young females in 2010 and one adult male with five youngs in 2011. The Protivín breeding group is supplemented by two couples of Philippine crocodile, which were imported to Europe in 2003 and were handed to the Protivín Crocodile ZOO as a confiscation.
The biggest problem in breeding of Philippine crocodile is big intraspecific agression. Therefore, philippine crocodiles are usually kept separatedly since the age of one year. We put them together only in breeding times. In other case, there is a risk, that animals would kill each other. But there is an exception. Male called Monty is comfortable with the presence of female for the whole year. On the other hand, male called Jack (imported from Avilon Zoo) killed two other females, when he was still in Philippines and he killed one female in Protivín Zoo as well. We appreciate, that it was right Jack, who impregnated the female called Minda in February 2013. On the 2nd May 2013 – 87 days after mating, this female (Minda) laid 17 eggs. The sign of fertilization of the eggs (white stripes on them) appeared on 10 of them. Jack was admitted to female called Minda on 4th February 2013 for 2 hours - between 11:00 and 13:00. The mating took place in water as well as on land. The date of admitting crocodiles together was set up according to vocalization between male and female. This was compared to another couple of Philippine crocodiles - Monty and Golda, which are kept together for the whole year. This couple performed nice foreplay before mating - including imposing each other and variety of sounds - rattling, grousing and barking. We compared this behaviour with the behaviour of couple Jack - Minda. However, they were keeping separatedly, they performed foreplay too. When the level of vocalization was same as Monty-Golda level, we admitted male Jack together with female Minda. They imposed each other with posing and loud vocalization. Afted 20 minutes they started mating. At first time on land, after that, they started mating in pool. After 2 hours of coupling, male Jack started to be really agressive, so we had to separate them. On the 2nd May 2013, 87 days after mating, female Minda laid 17 eggs . She was laying the eggs in the morning since 8:30 to 9:30. We were taking the eggs at the same time as she was laying the eggs. The eggs are stored in two incubators. Each is keeping up different temprerature - 32°C and 31°C. We´re still wainting for the clutch of eggs by female Golda. She is younger than female Minda, so it is possible, that she didn´t reach ovulation and following formation of the eggs yet.
According to all available informations, this clutch of the eggs of Philippine Crocodile is the first in Europe ever. Now, we are looking forward to the half of June, if there will be any hatchlings:) This year is very successfull for Protivín Crocodile Zoo. Since February till the begining of May, we got clutch of eggs from the Siamese crocodile (Crocodylus siamensis) - critically endangered species, next from the Mugger crocodile (Crocodylus palustris) and the Nile crocodile (Crocodylus niloticus). The last clutch of eggs is from critically endangered Philippine crocodile (Crocodylus mindorensis).
On 4th – 6th of May we were breeding sixteen crocodile´s babies of gharial (Gavialis gangeticus). It is first rearing in Europe and at the same time is first rearing outside the tropics.
Crocodile Zoo Protivín has great success with breeding endangered and critically endangered crocodile species. The first in Europe Zoo has bred a Cuban crocodile (Crocodylus rhombifer) in homozygous form a Mugger crocodile (Crocodilus palustris).
In the days from 16. 11 to 20. 11. 2015 We attended the fifth Congreso Internacional Tropical Animal Production at the Palacio de Convenciones de la Habana, where we presented our successful breeding of the critically endangered crocodile species.
