in this study, partial and complete replacement of live food ( artemia nauplii) with a microdiet was investigated in post-larval indian white shrimp, fenneropenaeus indicus . post-larvae (pl 1 ) were stocked into nine 20-l vessels (5-l water volume) at a density of 50 l -1 . shrimp were fed six times a day over 10 days. at the end of the feeding period, there was no significant difference in qu...
the present study investigates the effects of different routes of inulin administration as prebiotic on gut microbiota and survival rate of indian white shrimp post-larvae. four hundred and fifty indian white shrimp post-larvae (pl1) were stocked in nine tanks. the tanks were assigned into three treatments: feeding with inulin-treated (110 mg l-1) artemia nauplii (i-t), feeding with inulin-enri...
Postlarval and small juvenile Penaeus merguiensis were sampled fortnightly by beam trawls on the ebb tides over 4 years in the Matang mangroves on the west coast of peninsular Malaysia. Larger juveniles were sampled by bag nets on both the ebb and flood tides every fortnight over 5 years. Rainfall is consistently high throughout the year (>100 mm in each month) and the annual rainfall ranges fr...
The evolution of plants exhibiting different sexes, or dioecy, is correlated with a number of ecological and life-history traits such as woody growth form and animal-dispersed seeds, but the underlying causes of these associations are unclear. Previous work in seed plants has suggested that the evolution of fleshy cones or seeds may favour dioecy. In this study, we use a well-sampled molecular ...

Four hundred and fifty Indian white shrimp post-larvae (PL1) were stocked in nine tanks.

three experiments of 60 days duration were conducted in post larval stage of indian white shrimp, fenneropenaeus indicus, to explore the appropriate protein: lipid ratios in their diets. a common ingredient mixture consisting of; fish meal, shrimp meal, ground nut oil cake, cholesterol, lecithin, vitamins and minerals blended with chicken egg albumin, tapioca flour and cellulose (filler) was us...
اثر شدت و طول دوره نوری در یک دوره 40 روزه بر روی رشد و بازماندگی میگوی سفید هندی (fenneropenaeus indicus) انجام گرفت. بعد از سازگاری اولیه، میگوهای جوان سه ماهه با وزن اولیه 20/0±13/8 گرم در تانک های فایبرگلاسی با ظرفیت 300 لیتر با تراکم 12 عدد در هر تانک ذخیره شدند. با استفاده از لامپ های فلوئورسنت، شدت های نوری 50 و 1500 لوکس و فتوپریودهای 24 ساعت روشنایی کامل ـ بدون تاریکی و 12 ساعت روشنایی...
