CRC for Developing Northern Australia Scheme - Scholarship

Intensification of the redclaw crayfish (Cherax quadricarinatus) industry: the importance of sperm quality and male fertility to productivity.

Indicative Funding
$60,000 over 3 years
Summary
Expansion of the redclaw aquaculture industry is limited by suboptimal methods to produce fertilized eggs and craylings for pond production. Improvement of reproductive efficiency is dependent on several factors as well as understanding the underlying causes of subfertility. This project seeks to develop advanced reproductive technologies to characterise sperm quality; establish optimal diets; and develop artificial fertilization and sperm cryopreservation techniques for superior male broodstock to accelerate selective breeding.
Investigators
Jon Irish Aquino, John Cavalieri, Leo Nankervis and Estelle Venter in collaboration with Chaoshu Zeng and Lisa Elliot (College of Public Health, Medical & Vet Sciences, College of Science & Engineering and Australian Crayfish Hatchery)

CRC for Developing Northern Australia Scheme - Scholarship

Intensive Breeding Potential of Redclaw Crayfish, Cherax quadricarinatus: Evaluation and Improvements of Egg and Embryo Quality, and In Vitro Fertilization Perspectives

Indicative Funding
$30,000 over 2 years
Summary
The commercial expansion of redclaw is hampered by suboptimal methods used to produce fertilised eggs, asynchronous hatching, and mortalities of juveniles. This project seeks to characterise female broodstock fertility and improve hatchery productivity by developing tools to assess egg and embryo quality, induce gonadal maturation and egg release using dietary supplementation and hormonal treatments and by establishing artificial fertilization techniques. The study outcomes include validation of tools to select for egg quality and to develop strategies to facilitate synchronised spawning of redclaw within hatcheries to enhance reproductive performance and facilitate intensification of production.

Induction of gonadal maturation and egg release using hormones in redclaw crayfish (Cherax quadricarinatus) to facilitate intensive breeding for commercial juvenile production

Indicative Funding
$2,000 over 2 years
Summary
The commercial expansion of redclaw is hampered by suboptimal methods used to produce fertilised eggs, asynchronous hatching, and mortalities of juveniles that suggest broodstock fertility and nutrition need improvement. The proposed project will investigate induction of gonadal maturation and spawning using hormones in female redclaw. The outcomes of the study are validation and development of strategies to facilitate synchronised mating and spawning of redclaw within hatcheries in preventing suboptimal reproductive performance of redclaw in hatcheries. The established knowledge will help in understanding the hormone induced endocrine control of decapods and facilitate the development of artificial reproduction in intensively managed hatcheries.

Effect of pre-calving supplementation and yeast culture on colostrun secretion, calf health and growth

Indicative Funding
$12,697 (administered by University of Queensland)
Summary
It is estimated that one million calves die in Australia every year. Between mid-pregnancy and weaning, two-thirds of losses occur within a week of birth. Cows can take several days to achieve full lactation, leaving their calves vulnerable to dehydrate and die when environmental conditions are hot. Poor nutrition during late pregancy may cause hormonal imbalances and inadequate production of colostrum resulting in inadequate transfer of passive immunity to calves and increase calf loss. It is expected that supplemented cows will have better transfer of immunoglobulins to the mammary gland, leading to greater colustrum secretion and quality improving calf health.
