Journal ArticleDOI
TL;DR: The lability of sex-determination systems in fish makes some species sensitive to environmental pollutants capable of mimicking or disrupting sex hormone actions, and such observations provide important insight into potential impacts from endocrine disruptors, and can provide useful monitoring tools for impacts on aquatic environments.

2,283 citations


Journal ArticleDOI
TL;DR: The present results suggest that most of the fish oil can be replaced by the alternative sources tested without compromising growth and feed utilisation, but the histological changes observed suggest an impact of dietary lipid source on the transport and/or metabolism of fat in the fish.

597 citations


Journal ArticleDOI
TL;DR: The growth and nutritional content of four tropical Australian microalgal species, diatom Chaetoceros sp.

596 citations


Journal ArticleDOI
TL;DR: It is suggested that yellowtail larvae require a high level of dietary DHA for maximal growth and survival while diets containing elevated AA exert negative effects on larval pigmentation.

353 citations


Journal ArticleDOI
TL;DR: A computer particle tracking model DEPOMOD was developed that predicts the solids accumulation on the seabed arising from a fish farm and associated changes in the benthic faunal community and was validated using sediment trap studies.

353 citations


Journal ArticleDOI
TL;DR: The pilot-scale wastewater treatment system consisting of a free water surface (FWS) and a subsurface flow (SSF) constructed wetlands arranged in series was operated for around 8 months to examine system start-up phenomena and evaluate system performance in removing inorganic nitrogen and phosphate from aquaculture wastewater under various hydraulic loading rates.

Journal ArticleDOI
TL;DR: From 1995 to 1998, the Oceanic Institute operated a breeding program for Pacific white shrimp based on a selection index weighted equally for growth and resistance to Taura Syndrome Virus, which resulted in select shrimp from the Growth line being 21% larger than unselected control shrimp.

Journal ArticleDOI
TL;DR: It is indicated that an increase of dietary lipid level has protein-sparing effect, and the diet containing 42% DP and 14% DL (4.2 kcal DE/g diet) is optimal for growth and effective protein utilization of juvenile rockfish.

265 citations


Journal ArticleDOI
TL;DR: The aim of this study was to explore an in situ production of polyamines by Debaryomyces hansenii HF1 (DH), a yeast strain isolated from fish gut, in comparison with Saccharomyces cerevisiae X2180 (SC) (Goteborg University Collection).

263 citations


Journal ArticleDOI
TL;DR: The presence of a biofilm lead to reduced exportation of phosphorus (33% less phosphate) and to a higher output of nitrate+nitrite, instead of ammonium, and was also an important complementary food source for the shrimp, increasing their growth.

Journal ArticleDOI
TL;DR: In assessing the benefits and risks of ornamental aquaculture production, the cases where further development should and should not be pursued are developed.

Journal ArticleDOI
TL;DR: In this article, the authors showed that feeding diets containing oxidised oil significantly affected the activities of liver antioxidant defence enzymes and that dietary vitamin E partially abrogated these effects, however, the duration of feeding the diets of high prooxidative stress was observed to have a hitherto unknown effect, possibly the result of an adaptive process.

Journal ArticleDOI
TL;DR: Results show that the observed variance in reproductive success can be attributed to three main factors: gamete quality, sperm–egg interaction and differential viability among genotypes, and warn against using too limited a number of progenitors in breeding programmes.

Journal ArticleDOI
TL;DR: It is shown that no true advances have taken place in commercial eucheumatoid farming in over a decade and the capability to mitigate or eliminate pests, herbivores and diseases need to be addressed more closely.

Journal ArticleDOI
TL;DR: Examination of the foraging indicated that cod larvae rearing in higher light intensity captured prey more efficiently than larvae reared in low light, indicating that photoperiod and light levels could be reduced beyond 28 dph.

Journal ArticleDOI
TL;DR: Results showed that up to 80% of fish meal protein can be replaced by processed meat meal and blood meal coming from terrestrial animals with no adverse effects on growth, survival, and feed conversion ratio of E. coioides juveniles.

Journal ArticleDOI
TL;DR: The amount of postprandial ammonia excreted by silver perch within 24 h was linearly related to dietary protein level, and the protein efficiency ratio and productive protein value were inversely correlated with dietaryprotein level.

Journal ArticleDOI
TL;DR: Construction of an initial genetic linkage map for the black tiger shrimp, Penaeus monodon is reported, carried out using polymorphic markers derived from 23 Amplified Fragment Length Polymorphism (AFLP) primer pairs.

Journal ArticleDOI
TL;DR: The total replacement of raw starch by gelatinized starch significantly reduced growth and feed intake, while improving feed efficiency and overall, the best results were achieved with the diet RS/GS.

Journal ArticleDOI
TL;DR: It is demonstrated that additive genetic (co)variation for growth rate, feed conversion efficiency, and VHS resistance does exist within the farmed population of rainbow trout, and indicates that selective breeding for these traits can be successful.

Journal ArticleDOI
TL;DR: The environment of these farms might play important roles as reservoirs of bacteria carrying genetic determinants for high-level tetracycline resistance, prompting an important risk to public health for workers involved in fish culturing and processing.

Journal ArticleDOI
TL;DR: It is likely that with the use of tetraploid oysters, the farming of triploids will increase in the near future, and in countries where the production of Pacific oysters is based on hatchery supply of seed, this could increase sharply.

Journal ArticleDOI
TL;DR: An inhibitory substance was found to be a low molecular weight compound, heat stable, soluble in chloroform and resistant to proteolytic enzymes, which has potential applications for control of shrimp pathogenic vibrios in aquaculture systems.

Journal ArticleDOI
TL;DR: These data provide more precise information concerning nutrient and energy utilization of rockfish and will allow ingredient substitutions in practical feed based on levels of available nutrients.

Journal ArticleDOI
TL;DR: The potential of single cell heterotrophs as a partial substitute or replacement for fish-based ingredients in aquaculture diets is demonstrated and is shown to have significant benefits on the hatching rate of larvae.

Journal ArticleDOI
TL;DR: This synopsis of freshwater crayfish pests and pathogens was commissioned by the Australian Quarantine and Inspection Service for use as a resource document for hazard identification in the formal IRA process.

Journal ArticleDOI
TL;DR: A series of studies based on biochemical assays and electrophoretical observations was conducted in order to partially characterise various types of proteases present in the digestive tract of discus (Symphysodon aequifasciata), a highly valuable ornamental species.

Journal ArticleDOI
TL;DR: Iron supplementation significantly affected TCC and RBC and maximum values of these parameters were obtained at 336 mg of iron/kg diet, however, Ht and Hb were not affected by increasing levels of supplemental iron and interactions between dietary levels of CSM and iron.

Journal ArticleDOI
TL;DR: It was found that to keep inbreeding rates low, a minimum of 50 pairs of breeders should be selected and the number of progeny tested should be restricted and standardized to not less than 30–50 progeny per pair.

Journal ArticleDOI
TL;DR: Interestingly, PO activity markedly decreased in all tested salinities in the last 2 weeks, suggesting a partial suppression of the prophenoloxidase (proPO) system probably due to the stress caused by captivity.
