Final answer:
No, bait is not always present at fishing stations. Studies have shown that bait can introduce non-native species and contaminants, but it depends on the specific circumstances. Hence the correct answer is option B
Step-by-step explanation:
No, bait is not always present at fishing stations. In a study conducted by Litvak & Mandrak (1993), it was found that 41% of anglers admitted to releasing live bait after use. Bait buckets can transfer a variety of contaminant species, including undetected or misidentified non-target fishes and invertebrates. Additionally, Ludwig and Leitch (1996) found that 28.5% of bait samples purchased from retailers contained unexpected fish species. These findings suggest that bait can introduce non-native species and contaminants to fishing stations, but it is not always present.
Hence the correct answer is option B
