small red baitfish of the northern coast

Size
Length: 25–35 cm, Weight: 200–400 g
Lifespan
5–8 years
Diet
Small crustaceans and zooplankton. Filters food from the water using fine gill rakers. Forms large surface schools. Feeds most actively during dawn and dusk when plankton rises toward the surface.
Habitat
Coastal waters and open ocean from the surface down to 100 metres depth. Prefers temperate waters with high plankton productivity. Often found near the surface in large, fast-moving schools.
Range
Coastal waters of the North and South Islands from Northland to Otago. Most common off the east coast of both islands. Also found in southern Australia and the Southwest Pacific.
Endemism
Native
Main Threats
Bycatch in trawl and purse seine fisheries is the primary threat. Targeted as bait for recreational fishing. Climate change affecting plankton populations. No significant commercial market for human consumption exists for this species.
Population
Populations are considered stable across most of the range. Caught mainly as bycatch in the jack mackerel fishery. Also targeted by recreational fishers for use as bait. No species-specific stock assessment exists for this important forage fish.
Conservation Status
Not Threatened
Ruby-red schooling fish that forms enormous surface schools in coastal waters. The red baitfish is bright red when alive, a stunning sight against the blue water. But the colour fades quickly to silver after death. Dead fish are not red. Dead fish are silver. The colour is for the living. A fish that saves its best for when it matters. The transformation is rapid. The vibrancy is temporary. The utility is permanent. An important part of the marine food web. Red baitfish feed larger fish, seabirds and marine mammals. They are a classic forage fish, small and oily and abundant. They convert plankton into protein for the predators above. They filter food from the water using fine gill rakers. Feeding is most active at dawn and dusk when plankton rises toward the surface. A fish that is breakfast, lunch and dinner for half the ocean. The role is foundational. The contribution is massive. The recognition is low. The oily, strongly flavoured flesh is not popular for eating. But it makes excellent bait for game fishing, hence the common name. Red baitfish are often sold frozen as berley or bait. They chum the water to attract kingfish and other predators. A fish that is more useful dead than alive, at least from a fisherman's perspective. The value is instrumental. The purpose is external. The life is fuel. Populations are considered stable across most of the range. Red baitfish are caught mainly as bycatch in the jack mackerel fishery. No species-specific stock assessment exists. Better data collection is needed to ensure sustainable harvest levels for this important forage fish. The ignorance is systemic. The management is reactive. The risk is unquantified. The gap is wide. The reliance is high. A ruby-red schooler of coastal waters, feeding the predators, baiting the hooks, fading to silver after death. The school swirls beneath the surface, red and alive. Then the net comes down. The fish die. The red fades to silver. The change is chemical. The end is industrial. The cycle continues. The predators do not care about the colour. They just want to eat. The indifference is total. The hunger is absolute. No one told it otherwise.
