abstract = {Fucoid brown algae form extensive populations that dominate the intertidal and subtidal vegetation on temperate rocky shores. The persistence of populations of fucoid brown algae depends on their reproductive ability and the survival and growth of early life history stages (germlings) that are generally more susceptible to stressors than adults. In this study, the effects of temperature and salinity on germling development and fitness in the brown macroalgae Fucus serratus is assessed by studying rhizoid elongation, photosynthetic performance and survival in a matrix of four different temperatures and three salinities. It was hypothesized that both lower and higher than normal temperatures (12°C - 17°C) would constitute environmental stress and affect germling fitness, and that these effects would be exacerbated by sub-oceanic salinities below 32 psu. The results show that temperatures lower than the normal summer temperatures (6°C) have significant negative effects on both growth and survival as well as on photosynthesis, while there are no effects of higher than normal temperatures (22°C) alone. Sub-oceanic salinities affect growth and survival negatively, but only at the lowest salinity (18 psu), and have no effect on photosynthetic parameters. We conclude that higher water temperatures will not affect germling fitness, and thus F. serratus persistence, negatively, but low salinities and lower water temperatures will.},

abstract = {In the present investigation, vitellogenesis during ovarian development in the freshwater prawn Macrobrachium rosenbergii was assessed. Ovarian development was classified into five stages based on size, colour and texture of ovary. Interestingly, histological results clearly indicate that the oocyte development gradually increased from stages I to V based on the yolk material accumulation. Besides, the biochemical changes associated with ovarian development was also analyzed. On the other hand, vitellogenin (Vg) and vitellin (Vt) content during ovarian development in female prawn was quantified as a measure of reproductive activity.},

abstract = {The study set out to investigate the changes in macroinvertebrate community along different disturbance gradients within Nyando wetlands with an aim of determining how macroinvertebrates in Nyando wetlands respond to human disturbances. Triplicate macroinvertebrate samples were collected monthly from October 2010 to April 2011 using a scoop net (500 µm mesh size) in three transects. They were sorted live, counted and identified to genus level. Water samples for total phosphorus and total nitrogen were collected and analyzed using standard methods. Physico-chemical parameters were taken in-situ using electronic meters. Macroinvertebrates were analyzed for richness, diversity, dominance, and abundance. The abundance and diversity was correlated with physico-chemical parameters using Pearson correlation analysis. Kruskal-Wallis test was used to test spatial differences in macroinvertebrate community and repeated measures ANOVA to test variation in water quality parameters. A total of 45 genera were identified with hemipterans dominating. The statistical analysis revealed significant spatio-temporal differences in macroinvertebrate abundance and water quality parameters. Macroinvertebrate abundance showed a strong negative correlation with nutrient levels. Sites with higher disturbance recorded lower richness and abundance compared to the less disturbed sites. The results indicated that macroinvertebrates in Nyando wetlands respond to human disturbance and can be used to monitor ecological integrity of the wetland.},

abstract = {One hundred and thirty eight specimens of two cichlids, Sarotherodon galilaeus and Tilapia zillii from River Oshun, south-west Nigeria were examined for helminth parasites. The fish were caught using gill nets. In the laboratory, the acanthocephalans were killed and fixed in alcohol-formalin-acetic acid (AFA), stained with acetic hematoxylin, dehydrated using a graded alcohol series, cleared in xylene and mounted in DPX , while the trematodes were not stained before mounting on slides. Forty-five (32.6%) fish specimens had parasitic infection.  Two helminth species were recorded: a trematode, Clinostomum tilapiae (metacercaria), and an adult acanthocephalan, Neoechinorhynchus rutili. No sex-related differences (p > 0.05) were found in parasite burden, and there was no relationship between parasite burden and fish size (length and weight). It is concluded that the helminth parasite fauna of these species is depauperate},

abstract = {The rapid expansion of aquaculture in many parts of the world has supported vigorous research programmers on nutrition and the feeding of cultivated aquatic organisms. Teleosts, as an important source of food supply for human, have successfully adapted themselves to every type of aquatic habitat. This versatility is reflected in their mode of feeding. The digestive tract of fishes shows a remarkable diversity of morphological and functional characteristics. This is related to different feeding habits and to taxonomy, as well as to body shape and weight, size and sex. The morphology of post- gastric alimentary canal has also been studied from many species of fish because knowledge of fish's alimentary canal morphology is becoming increasingly important in fish digestive physiology and improvement of nutrition protocols. Identification of digestive tract structure is essential for understanding   the related histophysiological mechanisms and nutritional functions. This knowledge may help identify differences in microscopic anatomy of alimentary canal among various teleost species.  Fish intestine plays a vital role in digestion and absorption of dietary nutrients. The anatomical and histological characteristics of fish intestine are expected to be helpful for understanding the related functional mechanisms and feeding   habits, which can further be helpful for diagnosing some intestinal diseases and formulating suitable feeds. The histological characteristics of fish intestine can be affected by abiotic and biotic factors. In present review, the morphological features of teleostean fish's intestine have been discussed in many species to provide the best available information on intestinal structure and morphology.},

abstract = {Triploidy induction has been opted as an effective management tool in tilapia fish culture in the past. At present scenario, the production of tilapia monosex population through hormone treatment has become an important tool for aquaculturists to avoid unwanted reproduction and to produce single-sex individuals with larger growth potential. However, there is always the risk of public reacting badly to what they perceive as an unnecessary use of hormones in their food. Therefore a robust and reliable solution to overcome hurdles faced by tilapia aquaculture industry like advanced sexual maturation, unwanted and uncontrolled reproduction is always in demand. This article will discuss the efficacy of sterilization in tilapia using triploidy induction technique and its effect on altering the sex ratio and thereby how much this technique could revive the tilapia farming in the future.},
