(Elsevier, 1999)Juveniles of abalone, Haliotis asinina with mean initial weight and shell length of 0.6±0.03 g and 15±0.07 mm were fed practical diets for 90 days. The practical diets contained graded levels of protein from fish meal, ... -
Effects of alternate starvation and refeeding cycles on food consumption and compensatory growth of abalone, Haliotis asinina (Linnaeus).
(Blackwell Publishing, 2002)The effects of alternate starvation and refeeding on food consumption and compensatory growth of hatchery-bred abalone, Haliotis asinina (Linnaeus), were determined. Two groups of abalone juveniles (mean shell length ... -
Effects of elevated temperature on the different life stages of tropical mollusk, donkey's ear abalone (Haliotis asinina)
(Bioflux, 2017)The increase in sea surface temperature associated with climate change can cause tremendous impact on the different life stages of aquatic organisms, particularly on the tropical species. The present study investigates the ... -
Enriched Ulva pertusa as partial replacement of the combined fish and soybean meals in juvenile abalone Haliotis asinina (Linnaeus) diet
(Springer Verlag, 2020)The potential of enriched Ulva pertusa meal as feed ingredient in abalone juveniles, Haliotis asinina was evaluated. Four isonitrogenous and isolipidic diets were formulated which contain 27% protein and 5% lipid. Enriched ... -
Evaluation of density and cage design for the nursery and grow-out of the tropical abalone Haliotis asinina Linne 1758
(National Shellfisheries Association, 2013)The effect of stocking density and cage design on the growth, survival rate, and feed conversion ratio was evaluated for the nursery (11–15 mm in shell length) and juvenile grow-out (26–30 mm in shell length) of the tropical ... -
Evaluation of mucus, Navicula, and mixed diatoms as larval settlement inducers for the tropical abalone Haliotis asinina
(Elsevier, 2003)Different biological films reportedly effective in larval settlement of other abalone species were tested on the tropical abalone Haliotis asinina to determine the most effective settlement inducers for the species. Larval ... -
Evolution of genome size within the genus Haliotis (Vetigastropoda: Haliotidae)
(National Shellfisheries Association, 2018)Genome size (C-value) and the percentage of adenine and thymine nucleotides in the genome (AT content) are fundamental characteristics of every species, and very important parameters in molecular cytogenetic and phylogenic ... -
Feeding, growth and survival of abalone (Haliotis asinina Linnaeus 1758) reared at different stocking densities in suspended mesh cages in flow-through tanks
(San Carlos Publications, University of San Carlos, 2000)Feeding, growth and survival of hatchery-bred juvenile abalone, Haliotis asinina (mean initial shell lengths: 32 mm) stocked at 25, 50 and 100 m-2 of shelter surface area in mesh cages suspended in indoor ... -
First histopathological description of parasites and shell conditions of the donkey's ear abalone Haliotis asinina (Linnaeus, 1758) cultured in marine cages and land-based tanks in the Philippines
(National Shellfisheries Association, 2020-08-26)This study is the first attempt to assess parasitic infestations in grow-out cage culture and land-based grow-out tanks of the donkey's ear abalone Haliotis asinina in the Philippines. This histopathological study of the ... -
Flakes versus noodles as feed for the abalone Haliotis asinina, does form matter?
(Wiley, 2021-12)This paper reports the first use of thin flakes (310–315 μm thick) formulated diets as feed for the abalone Haliotis asinina. The study compared noodles and flakes prepared using refined and unrefined diets developed earlier ... -
Grow-out culture of tropical abalone, Haliotis asinina (Linnaeus) in suspended mesh cages with different shelter surface areas
(Kluwer Academic Publishers, 2001)This study investigated the effects of shelter surface area (SSA) on the feeding, growth and survival of the donkey-ear abalone, Haliotis asinina reared in mesh cages (0.38×0.38×0.28m) suspended in flow-through tanks (water ... -
Growth rate of the Philippine abalone, Haliotis asinina fed an artificial diet and macroalgae
(Elsevier, 1996)The growth rate of Haliotis asinina fed three diets was evaluated over a 120 day period. Juveniles fed the red alga Gracilariopsis heteroclada and an artificial diet grew faster in terms of both total body weight and shell ... -
