Developmental trends in the mouthparts during growth from juvenile to adult of the tropical freshwater crayfish, Cherax quadricarinatus von Martens, 1868 (Decapoda: Parastacidae)
(International Society of Invertebrate Reproduction and Development, 1997)The structure and setal armature of the mouthparts of Cherax quadricarinatus during development from juvenile to adult were examined using light and scanning electron microscopy. Significant general transformations include ... -
Effect of salinity on survival of Metapenaeus anchistus juveniles and subadults
(University of the Philippines in the Visayas, 1997)Survival of Metapenaeus anchistus (De Man) juveniles and subadults at 5, 15, 25, 35 (control) and 45 ppt salinity levels was determined and compared. Salinity levels lower than 35 ppt level were prepared by diluting pure ... -
The interactive effect of some environmental factors on the growth, agar yield and quality of Gracilariopsis bailinae (Zhang et Xia) cultured in tanks
(Walter de Gruyter, 1997)The single and interactive effects of light and temperature, salinity, and urea enrichment on the growth and agar yield and quality of Gracilariopsis bailinae were determined under indoor and outdoor tank conditions. Culture ... -
Growth rate, yield and economics of Gracilariopsis bailinae (Gracilariales, Rhodophyta) using fixed bottom long-line method
(Science and Technology Information Institute, 1997)Vegetative thalli of Gracilariopsis bailinae weighing 10 g each were tied to a 5-m monofilament line with plastic strips and laid horizontally on the substrate and were observed to grow at 30 d interval for 9 months. The ... -
Morphological abnormalities in hatchery-bred milkfish (Chanos chanos Forsskal) fry and juveniles
(Elsevier, 1997)Morphological abnormality has been observed in hatchery-bred milkfish juveniles. To characterize and quantify the occurrence of these anomalies, hatchery-bred milkfish juveniles from commercial nursery ponds were sampled, ... -
Influence of pyrite oxidation and soil acidification on some essential nutrient elements.
(Aquacultural Engineering Society (AES), 1997)Influence of soil acidification on some essential nutrient elements was observed experimentally during periodic leaching at 10-day intervals of pyritic soil materials. Pyritic soil in glass columns saturated with distilled ... -
Effect of some vertebrate and invertebrate hormones on the population growth, mictic female production, and body size of the marine rotifer Brachionus plicatilis Müller
(Springer Verlag, 1997)Eight vertebrate and invertebrate hormones were screened for their effect on population growth, mictic female production, and body size of the marine rotifer Brachionus plicatilis. Growth hormone (GH) or human chorionic ... -
Effects of different illumination levels on zooplankton abundance, feeding periodicity, growth and survival of the Asian sea bass, Lates calcarifer (Bloch), fry in illuminated floating nursery cages
(Elsevier, 1997)The effects of different illumination levels on Zooplankton abundance and feeding periodicity, growth and survival of hatchery-produced Asian sea bass, Lates calcarifer, fry in illuminated floating net cages were determined ... -
Larval rearing of the grouper Epinephelus suillus under laboratory conditions
(Elsevier, 1997)A protocol for rearing orange-spotted rockcod, Epinephelus suillus in the hatchery is described. The feeding regime consisted of Chlorella, Brachionus, Artemia and minced fish. With this regime, survival rates at Day 24 ... -
Preliminary investigation of feeding performance of larvae of early red-spotted grouper, Epinephelus coioides, reared with mixed zooplankton
(Springer Verlag, 1997)Larvae of red-spotted grouper, Epinephelus coioides, were reared in outdoor tanks with nauplii of copepods (mainly Pseudodiaptomus annandalei and Acartia tsuensis) and/or rotifers, Brachionus rotundiformis. Grouper larvae ... -
Detection of Vibrio penaeicida in kuruma prawn after transport
(Japanese Society of Fish Pathology, 1997)In Japan, vibriosis caused by Vibrio penaeicida usually occurs in cultured kuruma prawn (Penaeus japonicus) during summer and fall. The causative bacterium can easily be detected from overtly diseased prawns, but from ... -

(University of Philippines in the Visayas, 1997)The culture of tiger shrimps (Penaeus monodon) with and without green mussels (Perna viridis) was compared in terms of animal growth, survival, production, and pond water quality. Tiger shrimps (2.6 g) were stocked at ... -
Growth of juvenile Asian seabass, Lates calcarifer, fed varying carbohydrate and lipid levels
(Elsevier, 1997)Growth performance of juvenile seabass (initial mean body weight, 0.90 ± 0.04 g) fed varying carbohydrate and lipid levels were determined using practical diets in a 2 × 3 factorial experiment. Two carbohydrate levels (15 ... -
Changes in shrimp feed quality and effects on growth and survival of Penaeus monodon juveniles
(Elsevier, 1997)Five practical shrimp diets were formulated to contain 1, 10, 20, 50, and 100 g tetraethoxypropane (TEP) kg−1 diet. A diet with no added TEP served as the control. Diets were fed to Penaeus monodon (average ... -
