The study and research of abundance and diversity variation of fish larva (Ichthyoplankton stages) was done in Gowatr Bay during autumn 2006 - summer 2007. Five stations were selected for sampling, and Bongo-Net with 300µ mesh size was towing from bottom to surface. During of survey, totally 531 larvae belong to 11 families were collected and identified. The mean abundance estimated 12.17 larva...
Nervous necrosis virus (NNV) could infect many economic fish species and cause the fish nervous tissue necrosis vacuolization in histopathology. Once the fish is infected with NNV, 80-100% mortality will occour in grouper breeding farm. However, the immune system does not develop completely in grouper larva. Therefore, the traditional vaccine may not be effective during larva stage. This study ...
Anisakiasis and Pseudoterranovosis are human diseases caused by the ingestion of live Anisakidae larvae in raw, undercooked or lightly marinated fish. Larvae were collected from one salted cod sold for human consumption in a Sao Paulo market in 2013. One section of one brownish larva was used for molecular analyses. The partial COX2 gene sequence from the larva had a nucleotide identity of 99.8...

Fish larvae, like many adult fish, swim by undulating their body. However, their body size and swimming speeds put them in the intermediate flow regime, where viscous and inertial forces both play an important role in the interaction between fish and water. To study the influence of the relatively high viscous forces compared with adult fish, we mapped the flow around swimming zebrafish (Danio ...
a survey on the abundance and diversity of fish larvae along the iranian waters of the oman sea, extending from hormuz strait to gowatr bay, was carried out in 2009 (before and post monsoon). fish larva were collected by a bongo net (300 µ mesh size) and temperature, salinity, dissolved oxygen, ph, chlorophyll-a, clarity, nitrate, nitrite, silicate and sulfate by oceanic data recorder (ctd) and...
در این بررسی که طی سال های 1388 تا 1389 انجام گرفت، در مجموع هفت گونه و یازده جنس از پنج خانواده جمع آوری شدند که در بین آن ها، چهار جنس برای اولین بار از ایران و چهار گونه برای اولین بار از دنیا گزارش می شوند که به ترتیب با علامت های * و ** مشخص گردیده اند. لازم به ذکر است که بالاخانواده ی برای اولین بار از خاورمیانه گزارش می شود. اسامی گونه ها به ترتیب زیرگروه ها، بالاخانواده ها calyptosto...
Promoting black soldier fly (BSF) rearing in Benin to replace fishmeal fish diet could reduce production costs. This study aims set up a breeding technique of BSF as protein source. reproduction has been carried out sunlight. Two densities (8500 individuals/m3 and 10,500 individuals/m3) associated with 2 attractants (soybean pineapple waste) were tested on imago egg-laying. A larvarium prepupae...
The present study was conducted to determine the effect of saffron petal powder on the growth and activity of antioxidant enzymes in the grass carp larva (Ctenopharyngodon idella). Fish larva (0.75 ± 0.03 g and 4.39± 0.09 cm) were fed separately with four levels of saffron petal powder diets which were included; P0 (0%), P1 (2%), P2 (4%) and P3 (6%) for 60 days. One thousand two hundred fish we...
n-3 HUFA have been used as feed in rnass cultivation of fish larva.2'5i Recentlydocosahexaenoicacid(DHA)wasrepertedtobethernosteffective n-3 HUFA for the growth of fish fry,6'7) but there is no known method to enrich zooplankton specifically with DHA, In this paper we report on enriching Euglena gracilis with eicosapentaenoic acid (EPA) and DHA, E. gracitis cells are about SO"m in size, contain...
