Towards Shrimp Resources Investment in Iraq water

Malik Hassan Ali

Iraqi Journal of Aquaculture, Volume 12, Issue 2, Pages 1-6

The article highlighted the global importance and production of shrimp resources, whether it’s coming from the fisheries or from the aquaculture sector as well as it’s economy attribute in the international trade. Furthermore, it’s recognizing the status of the shrimp fishery in the marine and inland waters of Iraq, and the main negative factors impacted and reducing the shrimp stocks. Apparently no practical attempt has already been undertaken to culture the shrimp in the area, despite the availability of diverse water bodies. In conclusion, there is a great opportunity to developing the shrimp resources sector in Iraq by: (1) introduction and developing shrimp culture, (2) improving better management system for the shrimp fisheries.

Four different ways, were used to isolating the fungi from the shrimp Macrobrachium nipponense collected from the earthen ponds in Garmat Ali campus ,Basrah / Iraq, during the period of March to April 2013. Seven species have been diagnosed of Aspergillus flavus , A.niger, Aspergillus sp., A.terreus , Alternaria sp., Penicillium notatum and P. chrysogenum belong three genus of the fungus Aspergillus ,Alternaria and Penicillium, and differences were found in the number of isolates of each fungi species among March and April. The study confirmed that the presence of pathological fungi Aspergillus and Penicillium have a large impact on shrimp diseases fungal infection, especially when the culture conditions are not appropriate.

Iraqi Journal of Aquaculture, Volume 12, Issue 2, Pages 29-34

Shrimp Latreutes anoplonyx sample were collected from the northwest Arabian Gulf that found symbiotic interaction with the Medusa white Rhizostoma sp.. The diagnostic feature of the species is the present of one tooth on dorsal region of the carapace. The rostrum longer than antennular and flagella. The rostrum in the male is curved to down ward above the eye, while in the female more wider and curved upward. the teeth found on both sides of the rostrum, about 9 – 16 on dorsal side and very high and smooth, while in ventral side they were between 7 – 10 and more distance in the mid and high density in the top. The largest for female was 4 cm in length and the average shrimp lengths were between 1.2 – 4.0 cm.

This study includes an experimental hatchery design for the prawn Macrobrachium nipponense from the brackish water of Basrah region (Al-Mashab Marsh). This hatchery consist of five parts: maturation ponds (closed system), hatching of zoug jars, rearing of ponds to larva (nursery and concrete ponds), water tanks and food live of pond (fiberglass). The production capacity was 53,504-190,000 Zoea larvae, 32,355-99,560 Postlarvae. While production of the out ponds (cage two in mud and fiberglass ponds) were estimated between 4,347-24,098 larvae and 2,527-18,828 Postlarvae. Depending on results the total area of the earthen pond and the fiberglass tank, the potential production of Zoea larvae were estimated to be between 36,559-15,300,000 larvae, and between 21,248-11,954,400 Postlarvae. While the total production in all culture systems were 12,600,188-15,760,462 larvae, and between 9,753,349-12,197,630 Postlarvae.

Socioeconomic study for the wealth of marine shrimp in the territorial sea of Iraq

The present study was designed to investigate the contribution of shrimp fisheries and the related activities to the economy Iraq. For this purpose a socioeconomic information and data were collected for one year (2014) period. Three marine penaeid shrimps were constituted the majority of shrimp fisheries in Iraqi marine water, these are: Penaeus semisulcatus, Metapenaeus affinis and Parapenaopsis styliferus. University of Basrah institutes basically the Marine Science Center, apparently is the marine institute implemented researches and studies on shrimp landing have been recorded at Al Nasser fishing Society of the Basrah / Faw city. On the other side, the study concluded that any real and accurate data on shrimp landing can be only obtained from fisherman on the fishing boat of the field. In fact the marine fishing area of Iraq is very limited and the investigation shows that there are nearly 150- 250 fishing boats, 450 – 600 fisher man and 70 – 110 fishmonger contributing in the shrimp sector. However, their economy doesn’t restricted on shrimp, but, usually cornering other fish resources.
The results revealed that, the increasing of anthropological activities, overfishing, high by catch, the degradation of natural habitats such as coastal mudflats and Marshes and pollution are the basic factors reducing the shrimp stocks. For best monitoring and data collection of the shrimp resources, a networking information and data collection system is provided.

The feeding behavior experiments showed that the feeding of juveniles Macrobrachium nipponense are mostly and frequently occurred on the artificially net covered walls of the experimental tanks, this finding were observed in all the three tested bottom types (net covered wall (A), water column (B) and bottom (C); smooth or sand-clay bottom), and during the two tested feeding times (after 2 hr and 24 hr of experiments onset, and in both smooth and sand-clay tanks bottom. The estimated ratios were 80%, 9%, 11% and 73%, 12%, 14% at the (2 hour) period in smooth and sand-clay bottoms respectively, but during (24 hour) period were 72%, 12%, 16% and 67%, 12%, 21% at tanks of a smooth and sand-clay bottom respectively. As a conclusion of the observed results this prawn seems to be a pelagic feeding species.

The reproductive periods of Penaeus semisulcatus were investigated from July 2013 to Jun 2014, the results shows two reproductive peaks in this species, the first was in May and the second in December. Five stages were detected for oval development, these were: Immature, early mature, late mature, full mature and spent. The females have more weights have heaver ovaries.

Iraqi Journal of Aquaculture, Volume 12, Issue 2, Pages 88-100

A total of 140 specimens of penaeid shrimps from Metapenaeus affinis and Penaeus semisulcatus were collected from different parts of Iraqi coastal waters to detect three species of viruses Infectious Hypodermal and Hematopoietic Necrosis virus (IHHNV), White Spot Syndrome Virus (WSSV) and Monodon Baculovirus (MBV). PCR and nest PCR used to identify the viruses. The main important results in this study were detection two of more important viruses, (IHHNV) and (WSSV). So, we thought the studied shrimp was not suitable for aquaculture stock without screening because which may play a vertical and horizontal vector role. This study represents the first attempt to detect viral shrimp diseases in Iraq.

Laboratory experiments were carried out to express the effects of temperature, salinity and the combined effects of temperature–salinity on survival, growth and biomass of Artemia franciscana at 5 temperatures: 10, 20, 25, 30 and 35 ºC and 5 salinities: 35, 55, 75, 95 and 115 ‰. Temperature of 20 ºC and salinity of 55 ‰ showed best survivals (93 %), biomass (122.87 mg DW/L) and high growth (4.94 mm), whereas at 30 ºC and salinity of 95 ‰, the least survivals (21 %) was attained. However, the highest average growth was 6.1 mm attained at 30 ºC and 115 ‰, and the lowest growth was 1.49 mm at 10 ºC and 95 ‰, meanwhile, the lowest average biomass was 3.79 mg DW/L at 10 ºC and 115 ‰. Apparently, temperature of 20 ºC and salinity of 55 ‰ is the best combination for the local strain of A. franciscana from Basrah and is recommended for mass culture of this strain.
