A feed is one of the components that supports a cultivation business activity, fish feed must have good nutrition, especially a source of protein. Sources of protein for fish feed ingredients are generally imported, such as peanut meal and fish meal. Utilization of fishery and industrial waste as fish clothing is an effort to overcome the relatively high cost of feed. This study aims to determine the effect of adding formulations on the chemical properties of industrial waste-based catfish feed. The results showed that the more fish meal formulations that were added could increase the protein content in a range of 22.90% -39.90%, fat 5% -7.70%, and ash 5.79% -11.36%. The carbohydrate content decreased with a value range of 33.87% -57.08% and water 7.14% -12%. Fish feed formulations that are close to the SNI for catfish feed are found in treatment P1 with 39.90% protein content test results; water 7,18%; fat 7,7%; Ash 11.36% and carbohydrates 33.87%.

Seed priming is a pre-sowing treatment used to reduce stress effects in crops .This technique has been used to increase the germination rate of seeds mainly under unfavorable environmental condition. Crop productivity faces many problems like that unavailability of suitable condition that causes unbalanced seedling growth and poor germination. Hormones are essential to improve plant growth, development, crop yield quality and quantity. Auxin is essential hormones that improves germination of seeds and reduce stress effects. Laboratory experiment was conducted to study the effect of seed priming using different concentrations of IAA and IBA on carrot seeds (Daucus carota). In laboratory experiment, three concentrations of IAA and IBA (75 ppm, 50ppm, 25ppm) treated with distilled water with priming duration of 24 hours. Experiment was laid out in CRD with three replications. Data was collected to investigate the effect of seed priming with IAA and IBA under these condition like that (fresh weight, dry weight, speed of germination, root length, seed length, seedling length, final germination rate, mean germination time and dry matter content). Maximum fresh weight, final germination percentage, seedling length, energy of germination, speed of germination and mean germination rate was recorded IBA 75ppm. Maximum dry weight and dry matter content was observed IBA 25ppm.Maximum shoot length was recorded IBA 50ppm. Non-significant difference was recorded in root length.

Edamame is an agricultural product famous as vegetable soybeans. One of the edamame processed products is frozen edamame. Frozen edamame is a unique product frozen of souvenirs from Jember. This product is vulnerable to quality degradation due to the environment and consumer treatment. Consumers buy and carry products for souvenirs in a long journey and consumers are less precise in handling storage again when out of frozen storage. This study aims to improve the influence of storage room temperature with different time on the physical and chemical quality of original frozen edamame seeds and the influence of long storage with different time on the original organoleptic characteristics of frozen edamame. The results of tests conducted on the original edamame product during storage at room temperature affected the test results on color, texture, pH, total acid, moisture content and antioxidant activity, but had not effect on the total dissolved solids. The longer of storage at room temperature, the value of texture, color, total acid increases while the total dissolved solids, pH, moisture content and antioxidant activity decrease. The panelists organoleptic test assessment of the product during room temperature storage, panelists preferred P0 (0 hours) because the product was in fresh condition and of good quality compared to other treatments. During product storage at room temperature with different treatment times, the quality of the product has decreased in terms of color, texture, aroma, and taste.

This study discusses Nucleus, history of the discovery of the cell nucleus Structure and parts of the cell nucleus. All of them is the phisiology of animal and human. The cell nucleus (nucleus) can be defined as an organelle found in eukaryotic cells. Nucleoplasm The nucleoplasm is the liquid that is in the nucleus which is thick and transparent. The cell nucleus has many genes from DNA which are arranged and form structures called chromosomes. The endoplasmic reticulum consists of tubules, vesicles and flattened pockets that occupy the cytoplasmic space. The endoplasmic reticulum is a part of the cell that consists of a membrane system, which has a structure that resembles a multi-layered sac. These sacs are called cisternae.

Ectoparasites and heavy metal pollution pose health risks to both wild and aquaculture fish species. Here, we examine the ectoparasites of fish species (Hemichromis fasciatus, Liza falcipinnis and Sarotherodon galileus) from Abalama and Ilelema locations of the Buguma Creek, Rivers State, Nigeria, over a period of six months (February to July, 2020). Fish tissues (muscles, gills and gut) were also examined for heavy metals (Cr, Cd and Pb). Parasitological investigations were done following standard procedures, as well as the heavy metal analysis which was done using atomic absorption spectrophotometer after dry ashing-acid digestion. Two ectoparasites were isolated: Zeylanicobdella arugamensis from L. falcipinnis at both locations and Cymothoa exigua from H. fasciatus at Ilelema. In surface water, Cr concentration was 0.05). All fish species and tissues bioaccumulated appreciable concentrations of the heavy metals. Cr in fish tissues was within permissible limits, but all Cd and Pb values exceeded international permissible limits.

This parasitological study was carried out between February and May 2019 to determine the prevalence and intensity of helminthiasis in the rainbow lizard (Agama agama) in Okrika, Rivers State, Nigeria. A total of one hundred and fifty-one (151) specimens made up of 93 males and 75 females were caught by a local netting system during the day and anaesthesized with chloroform. Samples were collected from two stations (Ogoloma-Ama and Oba-Ama). After dissection, the esophagus, stomach, small intestine, rectum, liver, lungs, urinary bladder, heart and body cavity were searched for helminths using conventional methods. Five species of helminths belonging to Nematoda - Strongyluris brevicaudata, Parapharyngodon awokoyai, encysted Ascaridida larva, Cestoda - Oochoristica sp. and Trematoda - Mesocoelium spp - were recovered from infected lizards. Helminths infected one hundred and twenty-three (123) (82%) of the lizards. In Oba-Ama, forty-five (45) (76.3%) out of 59 and in Ogoloma-Ama, seventy-eight (78) (84.8%) out of 92 were infected with helminths. By abundance, in both locations, the males were more infected than their female counterparts with a prevalence of 51(93%) and 72(75%) (P

Generality and individuality are the inherent nature of everything, everything has both generality and individuality. Generality determines the basic nature of things, and individuality reveals the differences between things. According to the principle of dialectical materialism, the genes of organisms are divided into two types: General genes and individual genes. Genes shared by all biological individuals are called general genes, and genes unique to each individual organism are called individual gene. And use this classification method to discuss the three basic laws of genetics, heterosis theory and mutual affinity, and population genetics and biological evolution. It is concluded three basic laws of genetics are only relative to individual genes, unit traits controlled by general genes are not restricted by three basic laws of genetics, and the proportion of individual gene and general gene between parents has a decisive influence on the mutual affinity of parents and heterosis of hybrid generation, and the gradual process of the evolution of life from simple to complex, from low-level to high-level, is achieved by that the mutations to generate firstly new individual genes, and then the favorable individual genes are generalized, which the individuality genes are transformed into general genes that the individual characters can be transformed into the common characteristics of the population, and the process of natural selection is just to fix the favorable individual genes, make the traits controlled by them change into the general characteristics of this population, and to eliminate the unfavorable genes, and eliminate the unfavorable traits..

The long term impact of climate change is likely to affect food security and therefore prompts the agricultural sector to be more resilient to production and market risk, and uncertainties caused by these changes in climate. Choosing from a wide range of risk management tools can help farmers manage uncertainties and adapt to climate change. However, the choice of adoption of these risk management tools are greatly influenced by a number of factors. An empirical study was conducted to estimate the factors influencing the adoption choice of agricultural risk management tools by farmers in Akwa Ibom State, Nigeria. Multistage sampling procedure was employed to select the representative farmers for the study. Information were elicited from farmers using questionnaires. Factors influencing the adoption of crop diversification, insurance and contract farming were analyzed using multinomial logit approach. Empirical results revealed that the decision to adopt crop diversification and insurance were inversely and significantly affected by age of the farmers. Results further showed that farmers decision to adopt crop diversification and contract farming as risk management tools were positively and significantly influenced by the size of farmland at (p
