A method and a system for determining a weight estimate of food items include receiving an image of an outer surface of a food item. The image having a plurality of pixels each having a measure. By the measure of the pixels, a surface content of a first tissue which is distinct from a second tissue is identified. The surface content is translated into a volume content and a density parameter is recorded. An estimate of the weight is determined based on the volume content, the density parameter, and volume data identifying the volume of the food item.

A method for inspecting peeled shrimp by human operators in a culling station illuminated by ambient visible light and in a dark shell-detection booth illuminated by ultraviolet (UV) lamps. The UV radiation emitted by the lamps is filtered to remove visible light from the filtered UV irradiating the shrimp in the dark booth. Irradiated shrimp shell fluoresces and is detectable by the naked eye. A human operator in the dark booth detects the fluorescing shell and removes those shrimps.

A method for processing fish can include transporting fully intact fish to a floating vessel, at least one of weighing and sorting the fully intact fish, forming a layer of frozen slime on an outer surface of skin of the fully intact fish, and freezing the fully intact fish by moving the fully intact fish through an ultra-low air temperature region. Related systems and apparatuses are also provided.
