Fisheries importantly contribute to the animal protein supplies to many countries in the world, both the developed and developing ones. In developing countries, fisheries play an important role in food security. Fish is vulnerable to postharvest deterioration. Damage by post-harvest can be in the form of fleshly damage or spoilage. Mishandling of fish leads to physical damage whereas deprived hygiene and environments expedite spoilage. High temperature, inappropriate processing, storage and supply of fish are some of the phases that enhance the vulnerability of fish to physical damage. The study was conducted at Tema fishing harbour, Ghana to identify the types of post-harvest fish loss (PHFL) that occur at the landing site and during transportation. Questionnaires were randomly administered to 50 fishers (fishermen and transporters). The study identified burrito, herrings, redfish, moonfish, mackerel, and tuna as the fishes mostly harvested. Herrings were noted to have the highest spoilage vulnerability and the least was tuna. Physical losses were most frequently experienced by the fishers due to the mishandling of fish. The study recorded 12,600 kg (GH₵14,224.50) (2621.79$) of fish harvested during the study period of which 2,196 kg (GH₵2,418.20) (445.77$) was lost.

Nega","doi":"10.23880/ijoac-16000177","DOIUrl":"https://doi.org/10.23880/ijoac-16000177","url":null,"abstract":"Biological control is a method of controlling pests (including insects, mites, weeds and plant diseases) using other living organisms. There are three basic types of biological pest control strategies: importation (sometimes called classical biological control), augmentation and conservation. Natural enemies of the pests, also known as biological control agents, include predatory and parasitic insects, predatory vertebrates, nematode parasites, protozoan parasites, and fungal, bacterial, as well as viral pathogens. The best known bacterial biological control which can be introduced in order to control butterfly caterpillars is Bacillus thuringiensis. Viruses most frequently considered for the control of insects (usually sawflies and Lepidoptera) are the occluded viruses, namely NPV, cytoplasmic polyhedrosis (CPV), granulosis (GV), and entomopox viruses (EPN), the fungus Trichoderma viride. This has been used against Dutch elm disease, and to treat the spread of fungal and bacterial growth on tree wounds. The significance of Biological control agents are non– polluting and thus environmentally safe and acceptable. Usually they are species specific to targeted pest and weeds. The biological control discourages the use of environmentally and ecologically unsuitable chemicals, so it always leads to the establishment of natural balance. Ethiopia is one of the countries that use plant pest biocontrol methods mostly for weeds","PeriodicalId":174113,"journal":{"name":"International Journal of Oceanography & Aquaculture","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124359690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
