Background. Neuro-feedback (NFB) and physical activities are considered alternative treatments for children with ADHD that aims to optimize brain activity. Assessments of the behavioral efficacy of NF and physical interventions have produced inconsistent results. Like physical activity, yoga has been argued to be beneficial for improvement of neurological and physiological activity and behavior in a range of populations. Objectives. The present randomized controlled trial (RCT) evaluates the effects of NFB and yoga exercise intervention on sustained attention in children with ADHD. Methods. Using a multicenter three-way parallel group RCT design, children with ADHD, aged 7–11, were randomly assigned to NFB (n = 7), yoga (n = 7) or control (n = 7) over a period of 8 weeks. NFB training consisted of 24 sessions of theta/beta training at Cz and Yoga exercise training composed of 24 sessions of 45 minutes over 8 weeks. Sustained attention and memory were assessed using parameters derived from the Continuous Performance Test (CPT) Wechsler Intelligence Scale for Children-Revised (WISC-R). Results. Significant improvements in sustain attention and memory were observed over time in both Yoga and NFB compare to control group. To our knowledge, this is the first study that simultaneously evaluates NFB with Yoga treatment. Conclusion. These findings suggest that alternative therapies such as yoga exercises and NFB can be complementary to behavioral interventions for children with attention problem. Hence, the findings do not support NFB and yoga training applied as a stand-alone treatment in children with ADHD.

Artificial reefs are manmade materials deployed under water in order to improve environment and increase the exploitation of fishing area. Usage of artificial technic has developed due to increase of world population and need to supply of protein, aim to restoring of natural specially rehabilitation of demersal fishes. It has effected to increase the production in order sustainable exploitation. Coasts and Islands have destruction due to over harvesting from ecosystems and other activities by humans and natural, these caused many aquatic as demersal fishes has endangered in Persian Gulf and Oman Sea. The artificial reef is one way or method that can improve the environment and restore the aquatic. Iranian fisheries has established an artificial reefs area in west of Kish Island. This area has studied during one year, Data of assembled fishes and physical sampling were collected in seasonal during spring, summer, autumn and wintered. There were tow treatment for sampling as artificial reefs site and a control site. Collected data has analyzed and evaluated by SPSS and Exel. The results showed that there was significant difference between the sites and assembled fishes in artificial reefs were more than control site. Consequently the artificial reefs can be a tool and technic to improve the marine environment and increase the production of fishes, especially the demersal fishes.

The study of fluctuation of large pelagic stock (yellowfin tuna, skipjack tuna, longtail tuna, Narrow-barred Spanish mackerel ) in order to optimum exploitation in the Persian Gulf & Oman sea This study was carried out from 2005-07 in order to acquire some biological characteristics and population dynamic parameters for stock management and responsible fisheries. Thunnus albacares (yellowfin tuna), katsuwonus pelamis (skipjack tuna), Thunnus tonggol (longtail tuna) and scomberomorus commerson (Narrow- barred Spanish mackerel) were sampled. In total, length frequency of 9345 specimens of yellowfin tuna were analyzed. Size range was 37-172 cm. Teleost fishes were the most dominant prey species observed in this study (42%), Occurrence of Potunus Pelagicus was found to be the second (28%).Sthenoteuthis oualaniensis (22%), Natosquilla (5%) and octopus (3%) also were identified in the gut content of the yellowfin tuna. Length of maturity (50%) of yellow fin tuna was estimated 77.2 cm and spawning season was started from May. 8443 specimens of skipjack with size range of 32-90 cm were sampled. 48% of food items were teleost fishes. Squid and shrimp were also identified. Spawning season was begun from June. Growth parameters & fishing mortalities of yellow fin tuna and skipjack tuna were also estimated. Size range if longtail tuna was from 26-125cm Length infinity was estimated 132.3 cm with growth parameter of 0.35 per year. In total 10451 specimens of narrow- barred Spanish mackerel were sampled. Size range was from 20-164 cm. Teleost fishes were the most dominant prey species observed in the study (91.3%). Crustaceans (0.6%) and Indian squid (0.2%) also were identified in the specimens. Length maturity (50%) was estimated 83.6cm.

This report is about coral-reefs around Abumosa lsland from January 1998 till February 1999 by trap and underwater visual census. Total species belonging to genus and family were idemtified and length-weight relationship were estimated for more frequent species. Small tooth emperor (Lethrinus microdon) was predominate from other species. Catch per unit of effort (cpue) calculated for each trap (large, medium and small). Efforts were based on number of trap and day. Cupue of small and large traps was further in late summer compare other seasons. Results of catch analysis showed that no differ catch value (eatable, fishes, ornamental fishes and total catch) between small-medium and medium-large traps. Value catch wasn’t significant difference between three depth (0-10, 10-20 and 20-30m) and four geographical side, too. But, catch value of ornamental fishes was significant difference between depths 0-10 and 20-30 meter. Iranian Fisheries Science Research Institute Published
